2.2.0 (2024-05-01) #

Enhancements #

  • Allow configuration of generator per model class. Currently support specifying the constructor style to use. 
    const config = GeneratorConfig(ctorStyle: CtorStyle.allNamed);
const realmModel = RealmModel.using(baseType: ObjectType.realmObject, generatorConfig: config);

@realmModel
class _Person {
  late String name;
  int age = 42;
}
    will generate a constructor like: 
    Person({
  required String name,
  int age = 42,
}) { ... }
    (Issue #292)
  • Add privacy manifest to apple binaries. (Issue #1551)

Fixed #

  • Avoid: Attempt to execute code removed by Dart AOT compiler (TFA). (Issue #1647)
  • Fixed nullability annotations for the experimental API App.baseUrl and App.updateBaseUrl. The former is guaranteed not to be null, while the latter will now accept a null argument, in which case the base url will be restored to its default value. (Issue #1523)
  • App.users included logged out users only if they were logged out while the App instance existed. It now always includes all logged out users. (Core 14.6.0)
  • Fixed several issues around encrypted file portability (copying a "bundled" encrypted Realm from one device to another): (Core 14.6.0)
    • Fixed Assertion failed: new_size % (1ULL << m_page_shift) == 0 when opening an encrypted Realm less than 64Mb that was generated on a platform with a different page size than the current platform.
    • Fixed a DecryptionFailed exception thrown when opening a small (<4k of data) Realm generated on a device with a page size of 4k if it was bundled and opened on a device with a larger page size.
    • Fixed an issue during a subsequent open of an encrypted Realm for some rare allocation patterns when the top ref was within ~50 bytes of the end of a page. This could manifest as a DecryptionFailed exception or as an assertion: encrypted_file_mapping.hpp:183: Assertion failed: local_ndx < m_page_state.size().
  • Schema initialization could hit an assertion failure if the sync client applied a downloaded changeset while the Realm file was in the process of being opened. (Core 14.6.0)
  • Improve perfomance of "chained OR equality" queries for UUID/ObjectId types and RQL parsed "IN" queries on string/int/uuid/objectid types. (Core 14.6.0)
  • Fixed a bug when running a IN query (or a query of the pattern x == 1 OR x == 2 OR x == 3) when evaluating on a string property with an empty string in the search condition. Matches with an empty string would have been evaluated as if searching for a null string instead. (Core 14.6.2)

Compatibility #

  • Realm Studio: 15.0.0 or later.

Internal #

  • Using Core 14.6.2.
  • Flutter: ^3.19.0
  • Dart: ^3.3.0

2.1.0 (2024-04-17) #

Enhancements #

  • Improve file compaction performance on platforms with page sizes greater than 4k (for example arm64 Apple platforms) for files less than 256 pages in size (Core 14.4.0).
  • Added support for specifying key paths when listening to notifications on an object with the RealmObject.changesFor([List<String>? keyPaths]) method. The key paths indicates which changes in properties should raise a notification. 
    @RealmModel()
class _Person {
  late String name;
  late int age;
  late List<_Person> friends;
}

// ....

// Only changes to person.age and person.friends will raise a notification
person.changesFor(["age", "friends"]).listen( .... )
  • Add better hint to error message, if opening native library fails. (Issue #1595)
  • Added support for specifying schema version on Configuration.flexibleSync. This allows you to take advantage of an upcoming server-side feature that will allow schema migrations for synchronized Realms. (Issue #1599)
  • The default base url in AppConfiguration has been updated to point to services.cloud.mongodb.com. See https://www.mongodb.com/docs/atlas/app-services/domain-migration/ for more information. (Issue #1549)
  • Don't ignore private fields on realm models. (Issue #1367)
  • Improve performance of RealmValue.operator== when containing binary data. (PR #1628)

Fixed #

  • Using valid const, but non-literal expressions, such as negation of numbers, as an initializer would fail. (Issue #1606)
  • Backlinks mistakenly included in EJson serialization. (Issue #1616)
  • Fix an assertion failure "m_lock_info && m_lock_info->m_file.get_path() == m_filename" that appears to be related to opening a Realm while the file is in the process of being closed on another thread. (Core 14.5.0)
  • Fixed diverging history due to a bug in the replication code when setting default null values (embedded objects included). (Core 14.5.0)
  • Null pointer exception may be triggered when logging out and async commits callbacks not executed. (Core 14.5.0)
  • Comparing RealmValue containing a collection to itself would return false. Semantics changed to ensure reference equality always imply equality. (Issue [#1632])
  • Clearing a nested collection could end with a crash. (Core 14.5.1)
  • Removing nested collections in RealmValue for synced realms throws. (Core 14.5.1)
  • Fixed crash when integrating removal of already removed dictionary key. (Core 14.5.2)

Compatibility #

  • Realm Studio: 15.0.0 or later.

Internal #

  • Using Core 14.5.2.

2.0.0 (2024-03-20) #

Note: Using the newly added support for collections in RealmValue with Atlas Device Sync is currently in private preview. Reach out to the support team if you need it enabled for your app. Rolling it out across all apps is expected to happen in late April 2024.

Breaking Changes #

  • RealmValue.type is now an enum of type RealmValueType rather than Type. If you need the runtime type of the value wrapped in RealmValue, use RealmValue.value.runtimeType. (Issue #1505)

  • Renamed RealmValue.uint8List constructor to RealmValue.binary. (PR #1469)

  • Removed the following deprecated classes and members:

    • AppConfiguration.localAppName - was unused and had no effect
    • AppConfiguration.localAppVersion - was unused and had no effect
    • ClientResetError.isFatal - it was always true
    • ClientResetError.sessionErrorCode
    • SyncError.codeValue - can be accessed through SyncError.code.code
    • SyncError.category - categories were deprecated in 1.6.0
    • SyncError.detailedMessage - was always empty
    • SyncError constructor and SyncError.create factory - sync errors are created internally by the SDK and are not supposed to be constructed by users
    • SyncClientError, SyncConnectionError, SyncSessionError, SyncResolveError, SyncWebSocketError, GeneralSyncError - consolidated into SyncError as part of the error simplification in 1.6.0
    • RealmProperty.indexed - replaced by RealmProperty.indexType
    • SyncErrorCategory, SyncClientErrorCode, SyncConnectionErrorCode, SyncSessionErrorCode, SyncResolveErrorCode, SyncWebsocketErrorCode, GeneralSyncErrorCode - consolidated into SyncErrorCode as part of the error simplification in 1.6.0
    • User.provider - the provider is associated with each identity, so the value was incorrect for users who had more than one identity

  • The generated parts are now named .realm.dart instead of .g.dart. This is because the builder is now a PartBuilder, instead of a SharedPartBuilder. To migrate to this version you need to update all the part declarations to match, ie. part 'x.g.dart becomes part x.realm.dart and rerun the generator.

    This makes it easier to combine builders. Here is an example of combining with dart_mappable:

    import 'package:dart_mappable/dart_mappable.dart';
import 'package:realm_dart/realm.dart';

part 'part_builder.realm.dart';
part 'part_builder.mapper.dart';

@MappableClass()
@RealmModel()
class $Stuff with $StuffMappable {
  @MappableField()
  late int id;

  @override
  String toString() => 'Stuff{id: $id}';
}

final realm = Realm(Configuration.local([Stuff.schema]));
void main(List<String> arguments) {
  final s = realm.write(() => realm.add(Stuff(1), update: true));
  print(s.toJson()); // <-- realm object as json
  Realm.shutdown();
}

  • Removed SchemaObject.properties - instead, SchemaObject is now an iterable collection of Property. (Issue #1449)

  • SyncProgress.transferredBytes and SyncProgress.transferableBytes have been consolidated into SyncProgress.progressEstimate. The values reported previously were incorrect and did not accurately represent bytes either. The new field better conveys the uncertainty around the progress being reported. With this release, we're reporting accurate estimates for upload progress, but estimating downloads is still unreliable. A future server and SDK release will add better estimations for download progress. (Issue #1562)

  • Realm.logger is no longer settable, and no longer implements Logger from package logging. In particular you can no longer call Realm.logger.level =. Instead you should call Realm.logger.setLogLevel(RealmLogLevel level, {RealmLogCategory? category}) that takes an optional category. If no category is exlicitly given, then RealmLogCategory.realm is assumed.

    Also, note that setting a level is no longer local to the current isolate, but shared accross all isolates. At the core level there is just one process wide logger.

    Categories form a hierarchy and setting the log level of a parent category will override the level of its children. The hierarchy is exposed in a type safe manner with:

    sealed class RealmLogCategory {
  /// All possible log categories.
  static final values = [
  realm,
  realm.app,
  realm.sdk,
  realm.storage,
  realm.storage.notification,
  realm.storage.object,
  realm.storage.query,
  realm.storage.transaction,
  realm.sync,
  realm.sync.client,
  realm.sync.client.changeset,
  realm.sync.client.network,
  realm.sync.client.reset,
  realm.sync.client.session,
  realm.sync.server,
  ...

    The onRecord stream now pumps RealmLogRecords that include the category the message was logged to.

    If you want to hook up realm logging with conventional dart logging you can do:

    Realm.logger.onRecord.forEach((r) => Logger(r.category.toString()).log(r.level.level, r.message));

    If no isolate subscribes to Realm.logger.onRecord then the logs will by default be sent to stdout. (Issue #1578)

Enhancements #

  • Realm objects can now be serialized as EJSON. (Issue #1254) 
    import 'package:ejson/ejson.dart';
// ...
class _Event {
  late DateTime timestamp;
  late String message;
}
// ...
final ejson = toEJson(aRealmObject);
final anUnmanagedRealmObject = fromEJson<Event>(ejson);
  • Added isCollectionDeleted to RealmListChanges, RealmSetChanges, and RealmMapChanges which will be true if the parent object, containing the collection has been deleted. (Core 14.0.0)
  • Added isCleared to RealmMapChanges which will be true if the map has been cleared. (Core 14.0.0)
  • Querying a specific entry in a collection (in particular 'first and 'last') is supported. (Core 14.0.0) 
    class _Owner {
  late List<_Dog> dogs;
}

realm.query<Owner>('dogs[1].age = 5'); // Query all owners whose second dog element is 5 years old
realm.query<Owner>('dogs[FIRST].age = 5'); // Query all owners whose first dog is 5 years old
realm.query<Owner>('dogs[LAST].age = 5'); // Query all owners whose last dog is 5 years old
realm.query<Owner>('dogs[SIZE] = 10'); // Query all owners who have 10 dogs
  • Added support for storing lists and maps inside a RealmValue property. (Issue #1504) 
    class _Container {
  late RealmValue anything;
}

realm.write(() {
  realm.add(Container(anything: RealmValue.from([1, 'foo', 3.14])));
});

final container = realm.all<Container>().first;

final list = container.anything.asList(); // will throw if cast is invalid
for (final item in containerValue) {
  switch (item.type) {
    case RealmValueType.int:
      print('Integer: ${item.value as int}');
      break;
    case RealmValueType.string:
      print('String: ${item.value as String}');
      break;
    case RealmValueType.double:
      print('Double: ${item.value as double}');
      break;
  }
}

final subscription = list.changes.listen((event) {
  // The list changed
});
  • Added RealmValueType enum that contains all the possible types that can be wrapped by a RealmValue. (PR #1469)
  • Added support for accessing Set and Map types using the dynamic object API - obj.dynamic.getSet/getMap. (PR #1533)
  • Added RealmObjectBase.objectSchema that returns the schema for this object. In most cases, this would be the schema defined in the model, but in case the Realm is opened as dynamic (by providing an empty collection for schemaObjects in the config) or using FlexibleSyncConfiguration, it may change as the schema on disk changes. (Issue #1449)
  • Added Realm.schemaChanges that returns a stream of schema changes that can be listened to. Only dynamic and synchronized Realms will emit schema changes. (Issue #1449)
  • Improve performance of object notifiers with complex schemas and very simple changes to process by as much as 20% (Core 14.2.0).
  • Improve performance with very large number of notifiers as much as 75% (Core 14.2.0).

Fixed #

  • If you have more than 8388606 links pointing to one specific object, the program will crash. (Core 14.0.0)
  • A Realm generated on a non-apple ARM 64 device and copied to another platform (and vice-versa) were non-portable due to a sorting order difference. This impacts strings or binaries that have their first difference at a non-ascii character. These items may not be found in a set, or in an indexed column if the strings had a long common prefix (> 200 characters). (Core 14.0.0)
  • Ctor arguments appear in random order on generated classes, if the realm model contains many properties. (PR #1531)
  • Fixed an issue where removing realm objects from a List with more than 1000 items could crash. (Core 14.2.0)
  • Fix a spurious crash related to opening a Realm on background thread while the process was in the middle of exiting. (Core v14.3.0)
  • Fixed conflict resolution bug which may result in an crash when the AddInteger instruction on Mixed properties is merged against updates to a non-integer type. (Core v14.3.0)

Compatibility #

  • Realm Studio: 15.0.0 or later.
  • Fileformat: Generates files with format v24. Reads and automatically upgrade from fileformat v10. If you want to upgrade from an earlier file format version you will have to use RealmCore v13.x.y or earlier.

Internal #

  • Using Core v14.3.0

1.9.0 (2024-02-02) #

Enhancements #

  • Added User.changes stream that allows subscribers to receive notifications when the User changes - for example when the user's custom data changes or when their authentication state changes. (PR #1500)
  • Allow the query builder to construct >, >=, <, <= queries for string constants. This is a case sensitive lexicographical comparison. Improved performance of RQL queries on a non-linked string property using: >, >=, <, <=, operators and fixed behavior that a null string should be evaluated as less than everything, previously nulls were not matched. (Core 13.26.0-13-gd12c3)

Fixed #

  • Creating an AppConfiguration with an empty appId will now throw an exception rather than crashing the app. (Issue #1487)
  • Uploading the changesets recovered during an automatic client reset recovery may lead to 'Bad server version' errors and a new client reset. (Core 13.26.0-13-gd12c3)

Compatibility #

  • Realm Studio: 13.0.0 or later.

Internal #

  • Using Core 13.26.0-13-gd12c3

1.8.0 (2024-01-29) #

Enhancements #

  • Added RealmObject.getBacklinks<SourceType>('sourceProperty') which is a method allowing you to look up all objects of type SourceType which link to the current object via their sourceProperty property. (Issue #1480)
  • Added App.updateBaseUrl method for updating the App's base URL for switching between cloud and edge servers. The current Sync Session(s) must be paused before calling this method and the user must log in again afterwards before the Sync Session can be resumed. (PR #1454)

Fixed #

  • Fix a possible hang (or in rare cases crash) during notification handling. (Issue #1492)
  • Fix Flutter app build on Linux. A contribution from thiagokisaki. (PR #1488)
  • App was not using the current baseUrl value from AppConfiguration when it is created and always used the cached value stored upon the first contact with the server. (Core XX.XX.X)

Compatibility #

  • Realm Studio: 13.0.0 or later.

Internal #

  • Using Core 13.26.0

1.7.0 (2024-01-23) #

Enhancements #

  • Reworked how creating an App instance works across isolates:

    • The App(AppConfiguration) constructor should only be used on the main isolate. Ideally, it should be called once as soon as your app launches. If you attempt to use it on a background isolate (as indicated by Isolate.debugName being different from main), a warning will be logged.
    • Added a new method - App.getById that allows you to obtain an already constructed app on a background isolate. (Issue #1433)

  • Added support for fields of type Map<String, T> where T is any supported Realm type. You can define a model with a map like:

    @RealmModel()
class _LotsOfMaps {
  late Map<String, _Person?> persons;
  late Map<String, bool> bools;
  late Map<String, DateTime> dateTimes;
  late Map<String, Decimal128> decimals;
  late Map<String, double> doubles;
  late Map<String, int> ints;
  late Map<String, ObjectId> objectIds;
  late Map<String, RealmValue> realmValues;
  late Map<String, String> strings;
  late Map<String, Uint8List> datas;
  late Map<String, Uuid> uuids;
}

    The map keys may not contain . or start with $. (Issue #685)

  • Added a new exception - MigrationRequiredException that will be thrown when a local Realm is opened with a schema that differs from the schema on disk and no migration callback is supplied. Additionally, a helpLink property has been added to RealmException and its subclasses to provide a link to the documentation for the error. (Issue #1448)

  • Downgrade minimum dependencies to Dart 3.0.0 and Flutter 3.10.0. (PR #1457)

Fixed #

  • Fixed warnings being emitted by the realm generator requesting that xyz.g.dart be included with part 'xyz.g.dart'; for xyz.dart files that import realm but don't have realm models defined. Those should not need generated parts and including the part file would have resulted in an empty file with // ignore_for_file: type=lint being generated. (PR #1443)
  • Updated the minimum required CMake version for Flutter on Linux to 3.19. (Issue #1381)
  • Errors in user-provided client reset callbacks, such as RecoverOrDiscardUnsyncedChangesHandler.onBeforeReset/onAfterDiscard would not be correctly propagated and the client reset exception would contain a message like A fatal error occurred during client reset: 'User-provided callback failed' but no details about the actual error. Now SyncError has an innerError field which contains the original error thrown in the callback. (PR #1447)
  • Fixed a bug where the generator would not emit errors for invalid default values for collection properties. Default values for collection properties are not supported unless the default value is an empty collection. (PR #1406)
  • Bad performance of initial Sync download involving many backlinks (Issue #7217, Core 13.25.1)
  • Exceptions thrown during bootstrap application will now be surfaced to the user via the sync error handler rather than terminating the program with an unhandled exception. (PR #7197, Core 13.25.0).
  • Exceptions thrown during bootstrap application could crash the sync client with an !m_sess assertion if the bootstrap was being applied during sync::Session activation. (Issue #7196, Core 13.25.0).
  • If a SyncSession was explicitly resumed via App.reconnect() while it was waiting to auto-resume after a non-fatal error and then another non-fatal error was received, the sync client could crash with a !m_try_again_activation_timer assertion. (Issue #6961, Core 13.25.0)
  • Fixed several causes of "decryption failed" exceptions that could happen when opening multiple encrypted Realm files in the same process while using Apple/linux and storing the Realms on an exFAT file system. (Issue #7156, Core 13.24.1)
  • Fixed deadlock which occurred when accessing the current user from the App from within a callback from the User listener (Issue #7183, Core 13.24.1)
  • Having a class name of length 57 would make client reset crash as a limit of 56 was wrongly enforced (57 is the correct limit) (Issue #7176, Core 13.24.1)
  • Automatic client reset recovery on flexible sync Realms would apply recovered changes in multiple write transactions, releasing the write lock in between. This had several observable negative effects:
    • Other threads reading from the Realm while a client reset was in progress could observe invalid mid-reset state.
    • Other threads could potentially write in the middle of a client reset, resulting in history diverging from the server.
    • The change notifications produced by client resets were not minimal and would report that some things changed which actually didn't.
    • All pending subscriptions were marked as Superseded and then recreating, resulting in anything waiting for subscriptions to complete firing early. (PR #7161, Core 13.24.1).
  • If the very first open of a flexible sync Realm triggered a client reset, the configuration had an initial subscriptions callback, both before and after reset callbacks, and the initial subscription callback began a read transaction without ending it (which is normally going to be the case), opening the frozen Realm for the after reset callback would trigger a BadVersion exception (PR #7161, Core 13.24.1).
  • Changesets have wrong timestamps if the local clock lags behind 2015-01-01T00:00:00Z. The sync client now throws an exception if that happens. (PR #7180, Core 13.24.1)
  • Handle EOPNOTSUPP when using posix_fallocate() and fallback to manually consume space. This should enable android users to open a Realm on restrictive filesystems. (PR #7251, Core v13.26.0)
  • Application may crash with incoming_changesets.size() != 0 when a download message is mistaken for a bootstrap message. This can happen if the synchronization session is paused and resumed at a specific time. (PR #7238, Core v13.26.0, since v11.8.0)

1.6.1 (2023-11-30) #

Fixed #

  • Fixed an issue where connections to Atlas App Services would fail on Android with a certificate expiration error. (Issue #1430)
  • Fixed an issue with the generator where having multiple generated classes in the same file would result in multiple // ignore_for_file: type=lint lines being added, which itself was generating a lint warning. (Issue #1412)
  • Errors encountered while reapplying local changes for client reset recovery on partition-based sync Realms would result in the client reset attempt not being recorded, possibly resulting in an endless loop of attempting and failing to automatically recover the client reset. Flexible sync and errors from the server after completing the local recovery were handled correctly. (Core 13.24.0)
  • During a client reset with recovery when recovering a move or set operation on a List that operated on indices that were not also added in the recovery, links to an object which had been deleted by another client while offline would be recreated by the recovering client. But the objects of these links would only have the primary key populated and all other fields would be default values. Now, instead of creating these zombie objects, the lists being recovered skip such deleted links. (Core 13.24.0)
  • During a client reset recovery a Set of objects could be missing items, or an exception could be thrown that prevents recovery ex: "Requested index 1 calling get() on set 'source.collection' when max is 0". (Core 13.24.0)
  • Automatic client reset recovery would duplicate insertions in a list when recovering a write which made an unrecoverable change to a list (i.e. modifying or deleting a pre-existing entry), followed by a subscription change, followed by a write which added an entry to the list. (Core 13.24.0)

  • Full text search supports searching for prefix only. Eg. "description TEXT 'alex*'" (Core upgrade)
  • Unknown protocol errors received from the baas server will no longer cause the application to crash if a valid error action is also received. (Core upgrade)
  • Added support for server log messages that are enabled by sync protocol version 10. AppServices request id will be provided in a server log message in a future server release. (Core upgrade)
  • Simplified sync errors. The following sync errors and error codes are deprecated (#1387):
    • SyncClientError, SyncConnectionError, SyncSessionError, SyncWebSocketError, GeneralSyncError - replaced by SyncError.
    • SyncClientErrorCode, SyncConnectionErrorCode, SyncSessionErrorCode, SyncWebSocketErrorCode, GeneralSyncErrorCode, SyncErrorCategory - replaced by SyncErrorCode.
  • Throw an exception if File::unlock has failed, in order to inform the SDK that we are likely hitting some limitation on the OS filesystem, instead of crashing the application and use the same file locking logic for all the platforms. (Core upgrade)
  • Lift a restriction that prevents asymmetric objects from linking to non-embedded objects. (#1403)
  • Add ISRG X1 Root certificate (used by lets-encrypt and hence MongoDB) to SecurityContext of the default HttpClient. This ensure we work out-of-the-box on older devices (in particular Android 7 and earlier), as well as some Windows machines. (#1187, #1370)
  • Added new flexible sync API RealmResults.subscribe() and RealmResults.unsubscribe() as an easy way to create subscriptions and download data in background. Added named parameter to MutableSubscriptionSet.clear({bool unnamedOnly = false}) for removing all the unnamed subscriptions. (#1354)
  • Added cancellationToken parameter to Session.waitForDownload(), Session.waitForUpload() and SubscriptionSet.waitForSynchronization(). (#1354)

Fixed #

  • Fixed iteration after skip bug (#1409)
  • Crash when querying the size of a Object property through a link chain (Core upgrade, since v13.17.2)

  • Fixed crash in slab allocator (Assertion failed: ref + size <= next->first). (Core upgrade, since 13.0.0)
  • Sending empty UPLOAD messages may lead to 'Bad server version' errors and client reset. (Core upgrade, since v11.8.0)
  • If a user was logged out while an access token refresh was in progress, the refresh completing would mark the user as logged in again and the user would be in an inconsistent state. (Core 13.21.0)
  • Receiving a write_not_allowed error from the server would have led to a crash. (Core 13.22.0)
  • Fix interprocess locking for concurrent realm file access resulting in a interprocess deadlock on FAT32/exFAT filesystems. (Core 13.23.0)
  • Fixed RealmObject not overriding hashCode, which would lead to sets of RealmObjects potentially containing duplicates. (#1418)
  • realm.subscriptions.waitForSynchronization will now correctly receive an error if a fatal session error occurs that would prevent it from ever completing. Previously the future would never resolve. (Core 13.23.3)
  • Fixed FLX subscriptions not being sent to the server if the session was interrupted during bootstrapping. (Core 13.23.3)
  • Fixed application crash with 'KeyNotFound' exception when subscriptions are marked complete after a client reset. (Core 13.23.3)

  • Using Core 13.17.2

1.4.0 (2023-08-16) #

Enhancements #

  • Support ReamSet.freeze() (#1342)
  • Added support for query on RealmSet. (#1346)
  • Support for passing List, Set or Iterable arguments to queries with IN-operators. (#1346)

Fixed #

  • Fixed an early unlock race condition during client reset callbacks. (#1335)
  • Rare corruption of files on streaming format (often following compact, convert or copying to a new file). (Core upgrade, since v12.12.0)
  • Trying to search a full-text indexes created as a result of an additive schema change (i.e. applying the differences between the local schema and a synchronized realm's schema) could have resulted in an IllegalOperation error with the error code Column has no fulltext index. (Core upgrade, since v13.2.0).
  • Sync progress for DOWNLOAD messages from server state was updated wrongly. This may have resulted in an extra round-trip to the server. (Core upgrade, since v12.9.0)
  • Fixes infinite-loop like issue with await-for-yield over realm set change streams. (#1344)
  • Fixed issue with using flexibleSync in flutter test. (#1366)
  • Fixed a realm generator issue, when used in concert with MobX. (#1372)
  • Fix failed assertion for unknown app server errors (Core upgrade, since v12.9.0).
  • Testing the size of a collection of links against zero would sometimes fail (sometimes = "difficult to explain"). (Core upgrade, since v13.15.1)
  • Session.getProgressStream now returns a regular stream, instead of a broadcast stream. (#1375)
  • Add ISRG X1 Root certificate (used by lets-encrypt and hence MongoDB) to SecurityContext of the default HttpClient. This ensure we work out-of-the-box on older devices (in particular Android 7 and earlier), as well as some Windows machines. (#1187, #1370)

Compatibility #

  • Realm Studio: 13.0.0 or later.

Internal #

  • Using Core 13.17.2.

1.3.0 (2023-06-22) #

Enhancements #

  • Added support binary data type. (#1320)
  • Extended ClientResetError to return the backupFilePath where the backup copy of the realm will be placed once the client reset process has completed. (#1291)
  • Added CompensatingWriteError containing detailed error information about the writes that have been reverted by the server due to permissions or subscription view restrictions. The Configuration.flexibleSync.syncErrorHandler will be invoked with this error type when this error occurs (#1291).
  • Improve performance of elementAt, first, single and last on RealmResults (#1261, #1262, #1267).

Fixed #

  • The constructors of all SyncError types are deprecated. The sync errors will be created only internally (#1291).
  • Getting Backlink properties of unmanaged Realm objects will throw an error: "Using backlinks is only possible for managed objects" (#1293).
  • Properties in the frozen before Realm instance in the client reset callbacks may have had properties reordered which could lead to exceptions if accessed. (Core upgrade, since v13.11.0)

Compatibility #

  • Realm Studio: 13.0.0 or later.
  • Dart ^3.0.2 and Flutter ^3.10.2

Internal #

  • Synced realms will use async open to prevent overloading the server with schema updates. #1369)
  • Using Core 13.15.1

1.2.0 (2023-06-08) #

Enhancements #

  • Added support for Full-Text search (simple term) queries. (#1300)
  • To enable FTS queries on string properties, add the @Indexed(RealmIndexType.fullText) annotation.
  • To run queries, use the TEXT operator: realm.all<Book>().query("description TEXT \$0", "fantasy novel").

Fixed #

  • Fix the query parser, it needs to copy a list of arguments and own the memory. This will prevent errors like getting a different result from a query, if the list is modified after its creation and before the execution of the query itself. In the worst case scenario, if the memory is freed before the query is executed, this could lead to crashes, especially for string and binary data types. (Core upgrade, since core v12.5.0)
  • Fixed a potential crash when opening the realm after failing to download a fresh FLX realm during an automatic client reset (Core upgrade, since core v12.3.0)
  • Access token refresh for websockets was not updating the location metadata (Core upgrade, since core v13.9.3)
  • Using both synchronous and asynchronous transactions on the same thread or scheduler could hit the assertion failure "!realm.is_in_transaction()" if one of the callbacks for an asynchronous transaction happened to be scheduled during a synchronous transaction (Core upgrade, since core v11.8.0)
  • Fixed an issue where the generator would incorrectly consider a DateTime field a valid primary key (#1300).

Compatibility #

  • Realm Studio: 13.0.0 or later.

Internal #

  • Using Core 13.14.0.

1.1.0 (2023-05-30) #

Enhancements #

  • Add RealmResults.isValid (#1231).

  • Support Decimal128 datatype (#1192).

  • Realm logging is extended to support logging of all Realm storage level messages. (Core upgrade).

  • Realm.logger now prints by default to the console from the first Isolate that initializes a Realm in the application. (#1226). Calling Realm.logger.clearListeners() or Realm.logger.level = RealmLogLevel.off will turn off logging. If that is the first isolate it will stop the default printing logger. The default logger can be replaced with a custom implementation using Realm.logger = CustomLogger() from the first Isolate. Any new spawned Isolates that work with Realm will get a new Realm.logger instance but will not print by default. Realm.logger.level allows changing the log level per isolate.

  • Add logging at the Storage level (Core upgrade).

  • Performance improvement for the following queries (Core upgrade):

    • Significant (~75%) improvement when counting (query count) the number of exact matches (with no other query conditions) on a String/int/Uuid/ObjectId property that has an index. This improvement will be especially noticeable if there are a large number of results returned (duplicate values).
    • Significant (~99%) improvement when querying for an exact match on a Timestamp property that has an index.
    • Significant (~99%) improvement when querying for a case insensitive match on a Mixed property that has an index.
    • Moderate (~25%) improvement when querying for an exact match on a Boolean property that has an index.
    • Small (~5%) improvement when querying for a case insensitive match on a Mixed property that does not have an index.

  • Enable multiple processes to operate on an encrypted Realm simultaneously. (Core upgrade)

  • Improve performance of equality queries on a non-indexed mixed property by about 30%. (Core upgrade)

  • Improve performance of rolling back write transactions after making changes. If no KVO observers are used this is now constant time rather than taking time proportional to the number of changes to be rolled back. Rollbacks with KVO observers are 10-20% faster. (Core upgrade)

  • New notifiers can now be registered in write transactions until changes have actually been made in the write transaction. This makes it so that new notifications can be registered inside change notifications triggered by beginning a write transaction (unless a previous callback performed writes). (Core upgrade)

  • Very slightly improve performance of runtime thread checking on the main thread on Apple platforms. (Core upgrade)

Fixed #

  • Fixed a bug that may have resulted in arrays being in different orders on different devices (Core upgrade).

  • Fixed a crash when querying a mixed property with a string operator (contains/like/beginswith/endswith) or with case insensitivity (Core upgrade).

  • Querying for equality of a string on an indexed mixed property was returning case insensitive matches. For example querying for myIndexedMixed == "Foo" would incorrectly match on values of "foo" or "FOO" etc (Core upgrade).

  • Adding an index to a Mixed property on a non-empty table would crash with an assertion (Core upgrade).

  • SyncSession.pause() could hold a reference to the database open after shutting down the sync session, preventing users from being able to delete the realm (Core upgrade).

  • Fixed RealmResultsChanges.isCleared which was never set. It now returns true if the results collection is empty in the notification callback. This field is also marked as deprecated and will be removed in future. Use RealmResultsChanges.results.isEmpty instead.(#1265). (#1278).

  • Fix a stack overflow crash when using the query parser with long chains of AND/OR conditions. (Core upgrade)

  • SyncManager::immediately_run_file_actions() no longer ignores the result of trying to remove a realm. This could have resulted in a client reset action being reported as successful when it actually failed on windows if the Realm was still open (Core upgrade).

  • Fix a data race. If one thread committed a write transaction which increased the number of live versions above the previous highest seen during the current session at the same time as another thread began a read, the reading thread could read from a no-longer-valid memory mapping (Core upgrade).

  • Fixed a crash or exception when doing a fulltext search for multiple keywords when the intersection of results is not equal. (Core upgrade).

  • Don't report non ssl related errors during ssl handshake as fatal in default socket provider. (Core upgrade)

  • Performing a query like "{1, 2, 3, ...} IN list" where the array is longer than 8 and all elements are smaller than some values in list, the program would crash (Core upgrade)

  • Performing a large number of queries without ever performing a write resulted in steadily increasing memory usage, some of which was never fully freed due to an unbounded cache (Core upgrade)

  • Exclusion of words in a full text search does not work (Core upgrade)

  • Fixed a fatal error (reported to the sync error handler) during client reset (or automatic PBS to FLX migration) if the reset has been triggered during an async open and the schema being applied has added new classes. (Core upgrade), since automatic client resets were introduced in v11.5.0)

  • Full text search would sometimes find words where the word only matches the beginning of the search token (Core upgrade)

  • We could crash when removing backlinks in cases where forward links did not have a corresponding backlink due to corruption. We now silently ignore this inconsistency in release builds, allowing the app to continue. (Core upgrade)

  • If you freeze a Results based on a collection of objects, the result would be invalid if you delete the collection (Core upgrade)

Enhancements #

  • Improved error information returned when the realm_dart library failed to load. (#1143)

Fixed #

  • Improve performance of interprocess mutexes on iOS which don’t need to support reader-writer locking. The primary beneficiary of this is beginning and ending read transactions, which is now almost as fast as pre-v13.0.0 (Core upgrade).

0.11.0+rc (2023-01-30) #

This project is in Release Candidate stage.

Enhancements #

  • Add App.reconnect() providing a hint to Realm to reconnect all sync sessions.
  • Add Realm.refresh() and Realm.refreshAsync() support. (#1046)
  • Support change notifications property isCleared on list collections and sets. (#1128)

Fixed #

  • SyncSession.pause() allow users to suspend a Realm's sync session until it is explicitly resumed with SyncSession.resume(). Previously it could be implicitly resumed in rare cases. (Core upgrade)
  • Improve the performance of Realm.freeze() and friends (RealmObject.freeze(),RealmList.freeze(), RealmResults.freeze(), RealmSet.freeze()) by eliminating some redundant work around schema initialization and validation. (Core upgrade)
  • Include more details if an error occurs when merging object. (Core upgrade)
  • Value in List of Mixed would not be updated if new value is Binary and old value is StringData and the values otherwise matches. (Core upgrade)
  • When client reset with recovery is used and the recovery does not actually result in any new local commits, the sync client may have gotten stuck in a cycle with a A fatal error occurred during client reset: 'A previous 'Recovery' mode reset from <timestamp> did not succeed, giving up on 'Recovery' mode to prevent a cycle' error message. (Core upgrade)
  • Fixed diverging history in flexible sync if writes occur during bootstrap to objects that just came into view (Core upgrade)
  • Fix several data races when opening cached frozen Realms. New frozen Realms were added to the cache and the lock released before they were fully initialized, resulting in races if they were immediately read from the cache on another thread (Core upgrade).
  • Properties and types not present in the requested schema would be missing from the reported schema in several scenarios, such as if the Realm was being opened with a different schema version than the persisted one, and if the new tables or columns were added while the Realm instance did not have an active read transaction. (Core upgrade, since v13.2.0)
  • If a client reset w/recovery or discard local is interrupted while the "fresh" realm is being downloaded, the sync client may crash (Core upgrade)
  • Changesets from the server sent during FLX bootstrapping that are larger than 16MB can cause the sync client to crash with a LogicError. (Core upgrade)

0.9.0+rc (2023-01-13) #

This project is in Release Candidate stage.

Breaking Changes #

  • File format version bumped.
  • The layout of the lock-file has changed, the lock file format version is bumped and all participants in a multiprocess scenario needs to be up to date so they expect the same format. This requires an update of Studio. (Core upgrade)
  • Writing to a frozen realm throws RealmException instead of RealmError. (#974)

Enhancements #

  • Support setting maxNumberOfActiveVersions when creating a Configuration. (#1036)
  • Add List.move extension method that moves an element from one index to another. Delegates to ManagedRealmList.move for managed lists. This allows notifications to correctly report moves, as opposed to reporting moves as deletes + inserts. (#1037)
  • Support setting shouldDeleteIfMigrationNeeded when creating a Configuration.local. (#1049)
  • Add unknown error code to all SyncErrors: SyncSessionErrorCode.unknown, SyncConnectionErrorCode.unknown, SyncClientErrorCode.unknown, GeneralSyncErrorCode.unknown. Use unknown error code instead of throwing a RealmError. (#1052)
  • Add support for RealmValue data type. This new type can represent any valid Realm data type, including objects. Lists of RealmValue are also supported, but RealmValue itself cannot contain collections. Please note that a property of type RealmValue cannot be nullable, but can contain null, represented by the value RealmValue.nullValue(). (#1051)
  • Add support for querying using the model property names, even when the properties are mapped to a different name in the database. (#697)
  • ClientResetError.resetRealm now returns a bool to indicate if reset was initiated or not. (#1067)
  • Support SyncErrorCategory.resolve, SyncResolveError and SyncResolveErrorCode for network resolution errors when sync.

Fixed #

  • Support mapping into SyncSessionErrorCode for "Compensating write" with error code 231. (#1022)
  • Errors from core will be raised correctly for beginWriteAsync and commitAsync. (#1042)
  • The realm file will be shrunk if the larger file size is no longer needed. (Core upgrade)
  • Most of the file growth caused by version pinning is eliminated. (Core upgrade)
  • Fetching a user's profile while the user logs out would result in an assertion failure. (Core upgrade)
  • Removed the ".tmp_compaction_space" file being left over after compacting a Realm on Windows. (Core upgrade).
  • Restore fallback to full barrier when F_BARRIERSYNC is not available on Apple platforms. (Core upgrade, since v0.8.0+rc)
  • Fixed wrong assertion on query error that could result in a crash. (Core upgrade)
  • Writing to a read-only realm throws RealmException instead of blocking the isolate. (#974)
  • Fix no notification for write transaction that contains only change to backlink property. (Core upgrade)
  • Fixed wrong assertion on query error that could result in a crash. (Core upgrade)
  • Use random tmp directory for download. (#1060)
  • Bump minimum Dart SDK version to 2.17.5 and Flutter SDK version to 3.0.3 due to an issue with the Dart virtual machine when implementing Finalizable. (dart-lang/sdk#49075)
  • Support install command in flutter projects that use unit and widget tests. (#870)

Breaking Changes #

  • FunctionsClient.call no longer accepts a null for the optional functionsArgs parameter, but it is still optional. (#1025)

Fixed #

  • Allow backlinks between files. (#1015)
  • Fix issue with accessing properties after traversing a backlink. (#1018)
  • Bootstraps will not be applied in a single write transaction - they will be applied 1MB of changesets at a time, or as configured by the SDK (Core upgrade).
  • Fix database corruption and encryption issues on apple platforms. (Core upgrade)

Compatibility #

  • Realm Studio: 12.0.0 or later.

Internal #

  • Using Core 12.12.0.

0.7.0+rc (2022-11-04) #

This project is in Release Candidate stage.

Breaking Changes #

  • SyncClientResetErrorHandler is renamed to ClientResetHandler. SyncClientResetError is renamed to ClientResetError. ManualSyncClientResetHandler is renamed to ManualRecoveryHandler.
  • Default resync mode for FlexibleSyncConfiguration is changed from manual to recoverOrDiscard. In this mode Realm attempts to recover unsynced local changes and if that fails, then the changes are discarded. (#925)
  • Added path parameter to Configuration.disconnectedSync. This path is required to open the correct synced realm file. (#1007)

Enhancements #

  • Added MutableSubscriptionSet.removeByType for removing subscriptions by their realm object type. (#317)
  • Added User.functions. This is the entry point for calling Atlas App functions. Functions allow you to define and execute server-side logic for your application. Atlas App functions are created on the server, written in modern JavaScript (ES6+) and executed in a serverless manner. When you call a function, you can dynamically access components of the current application as well as information about the request to execute the function and the logged in user that sent the request. (#973)
  • Support results of primitives, ie. RealmResult<int>. (#162)
  • Support notifications on all managed realm lists, including list of primitives, ie. RealmList<int>.changes is supported. (#893)
  • Support named backlinks on realm models. You can now add and annotate a realm object iterator field with @Backlink(#fieldName). (#996)
  • Added Realm file compaction support. (#1005)
  • Allow @Indexed attribute on all indexable type, and ensure appropriate indexes are created in the realm. (#797)
  • Add parent getter on embedded objects. (#979)
  • Support Client Resets. Atlas App Services automatically detects the need for client resets and the realm client automatically performs it according to the configured callbacks for the type of client reset handlers set on FlexibleSyncConfiguration. A parameter clientResetHandler is added to Configuration.flexibleSync. Supported client reset handlers are ManualRecoveryHandler, DiscardUnsyncedChangesHandler, RecoverUnsyncedChangesHandler and RecoverOrDiscardUnsyncedChangesHandler. RecoverOrDiscardUnsyncedChangesHandler is the default strategy. (#925) An example usage of the default clientResetHandler is as follows:
      final config = Configuration.flexibleSync(user, [Task.schema],
        clientResetHandler: RecoverOrDiscardUnsyncedChangesHandler(
          // The following callbacks are optional.
          onBeforeReset: (beforeResetRealm) {
            // Executed right before a client reset is about to happen.
            // If an exception is thrown here the recovery and discard callbacks are not called.
          },
          onAfterRecovery: (beforeResetRealm, afterResetRealm) {
            // Executed right after an automatic recovery from a client reset has completed.
          },
          onAfterDiscard: (beforeResetRealm, afterResetRealm) {
            // Executed after an automatic recovery from a client reset has failed but the Discard has completed.
          },
          onManualResetFallback: (clientResetError) {
            // Handle the reset manually in case some of the callbacks above throws an exception
          },
        )
    );

Fixed #

  • Fixed a wrong mapping for AuthProviderType returned by User.provider for google, facebook and apple credentials.
  • Opening an unencrypted file with an encryption key would sometimes report a misleading error message that indicated that the problem was something other than a decryption failure (Core upgrade)
  • Fix a rare deadlock which could occur when closing a synchronized Realm immediately after committing a write transaction when the sync worker thread has also just finished processing a changeset from the server. (Core upgrade)
  • Fixed an issue with Configuration.disconnectedSync where changing the schema could result in migration exception. (#999)
  • Added a better library load failed message. (#1006)

Compatibility #

  • Realm Studio: 12.0.0 or later.

Internal #

  • Using Core 12.11.0.

0.6.0+beta (2022-10-21) #

This project is in the Beta stage. The API should be quite stable, but occasional breaking changes may be made.

Enhancements #

  • Added support for asynchronous transactions. (Issue #802)
    • Added Transaction which is a class that exposes an API for committing and rolling back an active transaction.
    • Added realm.beginWriteAsync which returns a Future<Transaction> that resolves when the write lock has been obtained.
    • Added realm.writeAsync which opens an asynchronous transaction, invokes the provided callback, then commits the transaction asynchronously.
  • Support Realm.open API to asynchronously open a local or synced Realm. When opening a synchronized Realm it will download all the content available at the time the operation began and then return a usable Realm. (#731)
  • Add support for embedded objects. Embedded objects are objects which are owned by a single parent object, and are deleted when that parent object is deleted or their parent no longer references them. Embedded objects are declared by passing ObjectType.embedded to the @RealmModel annotation. Reassigning an embedded object is not allowed and neither is linking to it from multiple parents. Querying for embedded objects directly is also disallowed as they should be viewed as complex structures belonging to their parents as opposed to standalone objects. (Issue #662)
@RealmModel()
class _Person {
  late String name;

  _Address? address;
}

// The generated `Address` class will be an embedded object.
@RealmModel(ObjectType.embedded)
class _Address {
  late String street;
  late String city;
}

Fixed #

  • Added more validations when using User.apiKeys to return more meaningful errors when the user cannot perform API key actions - e.g. when the user has been logged in with API key credentials or when the user has been logged out. (Issue #950)
  • Fixed dart run realm_dart generate and flutter pub run realm generate commands to exit with the correct error code on failure.
  • Added more descriptive error messages when passing objects managed by another Realm as arguments to Realm.add/delete/deleteMany. (PR #942)
  • Fixed a bug where list.remove would not correctly remove the value if the value is the first element in the list. (PR #975)

Compatibility #

  • Realm Studio: 12.0.0 or later.

Internal #

  • Using Core 12.9.0

0.5.0+beta (2022-10-10) #

This project is in the Beta stage. The API should be quite stable, but occasional breaking changes may be made.

Breaking Changes #

  • Fixed an issue that would cause passwords sent to the server (e.g. Credentials.EmailPassword or EmailPasswordAuthProvider.registerUser) to contain an extra empty byte at the end. (PR #918). Notice: Any existing email users might need to be recreated because of this breaking change.

Enhancements #

  • Added support for "frozen objects" - these are objects, queries, lists, or Realms that have been "frozen" at a specific version. All frozen objects can be accessed and queried as normal, but attempting to mutate them or add change listeners will throw an exception. Realm, RealmObject, RealmList, and RealmResults now have a method freeze() which returns an immutable version of the object, as well as an isFrozen property which can be used to check whether an object is frozen. (#56)
  • You can now set a realm property of type T to any object o where o is T. Previously it was required that o.runtimeType == T. (#904)
  • Performance of indexOf on realm lists has been improved. It now uses realm-core instead of the generic version from ListMixin. (#911)
  • Performance of remove on realm list has been improved. It now uses indexOf and removeAt. (#915)
  • Added support for migrations for local Realms. You can now construct a configuration with a migration callback that will be invoked if the schema version of the file on disk is lower than the schema version supplied by the callback. (#70) Example: 
    final config = Configuration.local([Person.schema], schemaVersion: 4, migrationCallback: (migration, oldSchemaVersion) {
  if (oldSchemaVersion == 1) {
    // Between v1 and v2 we removed the Bar type
    migration.deleteType('Bar');
  }

  if (oldSchemaVersion == 2) {
    // Between v2 and v3 we fixed a typo in the 'Person.name' property.
    migration.renameProperty('Person', 'nmae', 'name');
  }

  if (oldSchemaVersion == 3) {
    final oldPeople = migration.oldRealm.all('Person');
    for (final oldPerson in oldPeople) {
      final newPerson = migration.findInNewRealm<Person>(oldPerson);
      if (newPerson == null) {
        // That person must have been deleted, so nothing to do.
        continue;
      }

      // Between v3 and v4 we're obfuscating the users' exact age by storing age group instead.
      newPerson.ageGroup = calculateAgeGroup(oldPerson.dynamic.get<int>('age'));
    }
  }
});
  • Added support for realm list of nullable primitive types, ie. RealmList<int?>. (#163)
  • Allow null arguments on query. (#871)
  • Added support for API key authentication. (Issue #432)
    • Expose User.apiKeys client - this client can be used to create, fetch, and delete API keys.
    • Expose Credentials.apiKey that enable authentication with API keys.
  • Exposed User.accessToken and User.refreshToken - these tokens can be used to authenticate against the server when calling HTTP API outside of the Dart/Flutter SDK. For example, if you want to use the GraphQL. (PR #919)
  • Added support for encryptionKey to Configuration.local, Configuration.flexibleSync and Configuration.disconnectedSync so realm files can be encrypted and existing encrypted files from other Realm sources opened (assuming you have the key)(#920)

Fixed #

  • Previously removeAt did not truncate length. (#883)
  • List.length= now throws, if you try to increase length. This previously succeeded silently. (#894).
  • Queries on lists were broken. (#909) Example: 
    expect(realm.all<Person>(), [alice, bob, carol, dan]); // assume this pass, then ...
expect(team.players.query('TRUEPREDICATE'), [alice, bob]); // <-- ... this fails and return the same as realm.all<Person>()
  • Queries on results didn't filter the existing results. (#908). Example 
    expect(realm.query<Person>('FALSEPREDICATE').query('TRUEPREDICATE'), isEmpty); //<-- Fails if a Persion object exists
  • Fixed copying of native structs for session errors and http requests. (#924)
  • Fixed a crash when closing the SyncSession on App instance teardown. (#5752)
  • Fixed sporadic generator failure. (#879)
  • Exceptions thrown by user code inside the Configuration.initialDataCallback are now properly surfaced back to the Realm() constructor. (#698)

Compatibility #

  • Realm Studio: 12.0.0 or later.

Internal #

  • Uses Realm Core v12.9.0
  • Added tracking of child handles for objects/results/lists obtained from an unowned Realm. This ensures that all children are invalidated as soon as the parent Realm gets released at the end of the callback. (Issue #527)
  • Added an action to enforce that the changelog is updated before a PR is merged (Issue #939)

0.4.0+beta (2022-08-19) #

This project is in the Beta stage. The API should be quite stable, but occasional breaking changes may be made.

Breaking Changes #

  • Changed the name of Configuration.schema to Configuration.schemaObjects and changed its type to Iterable<SchemaObject>. You can now access the Realm's schema via the new Realm.schema property. #495)

Enhancements #

  • Expose an API for string-based access to the objects in the Realm. Those are primarily intended to be used during migrations, but are available at all times for advanced use cases. #495)
  • Added Realm.schema property exposing the Realm's schema as passed through the Configuration or read from disk. #495)

Fixed #

  • Lifted a limitation that only allowed non-nullable primary keys. (#458)
  • Fix boolean values get/set after ffigen update. (#854)

Compatibility #

  • Realm Studio: 12.0.0 or later.

Internal #

  • Uses Realm Core v12.5.1

0.3.2+beta (2022-08-16) #

This project is in the Beta stage. The API should be quite stable, but occasional breaking changes may be made.

  • Support Credentials.jwt for login user with JWT issued by custom provider . (#715)
  • Support Credentials.function for login user with Custom Function Authentication Provider. (#742)
  • Added update flag on Realm.add and Realm.addAll to support upserts. (#668)
  • Allow multiple anonymous sessions. (PR #5693).
  • Introducing query parser support for constant list expressions such as fruit IN {'apple', 'orange'}. This also includes general query support for list vs list matching such as NONE fruits IN {'apple', 'orange'}. (Issue #4266)
  • SubscriptionSet::refresh() does less work if no commits have been made since the last call to refresh(). (PR #5695)
  • Reduce use of memory mappings and virtual address space (PR #5645). Also fixes some errors (see below)

Fixed #

  • Use Dart 2.17 Finalizable to ensure lexically scoped lifetime of finalizable resources (Realm, App, etc.). (#754)
  • Fix crash after hot-restart. (#711 and PR #5570)

  • Fix a data race when committing a transaction while multiple threads are waiting for the write lock on platforms using emulated interprocess condition variables (most platforms other than non-Android Linux).
  • Fix some cases of running out of virtual address space (seen/reported as mmap failures) (PR #5645)

Internal #

  • Added a command to realm_dart for deleting Atlas App Services applications. Usage: dart run realm_dart delete-apps. By default it will delete apps from http://localhost:9090 which is the endpoint of the local docker image. If --atlas-cluster is provided, it will authenticate, delete the application from the provided cluster. (PR #663)
  • Uses Realm Core v12.5.1

0.3.1+beta (2022-06-07) #

This project is in the Beta stage. The API should be quite stable, but occasional breaking changes may be made.

Fixed #

0.3.0+beta (2022-06-02) #

This project is in the Beta stage. The API should be quite stable, but occasional breaking changes may be made.

Breaking Changes #

  • Made all Configuration fields final so they can only be initialized in the constructor. This better conveys the immutability of the configuration class. (#455)

  • Support the following SyncSession API:
    • realmPath returning the path of the Realm for the session.
    • state returning the current state of the session.
    • connectionState returning the current state of the connection.
    • connectionStateChanges returns a Stream that emits connection state updates.

  • Support SyncClientResetHandler in FlexibleSyncConfiguration. (#608)
  • [Dart] Added Realm.Shutdown method to allow normal process exit in Dart applications. (#617)

Fixed #

  • Fixed an issue that would result in the wrong transaction being rolled back if you start a write transaction inside a write transaction. (#442)
  • Fixed boolean value persistence (#474)

Internal #

  • Added a command to deploy an Atlas App Services application to realm_dart. Usage: dart run realm_dart deploy-apps. By default it will deploy apps to http://localhost:9090 which is the endpoint of the local docker image. If --atlas-cluster is provided, it will authenticate, create an application and link the provided cluster to it. (PR #309)
  • Unit tests will now attempt to lookup and create if necessary Atlas App Services applications (similarly to the above mentioned command). See test.dart/setupBaas() for the environment variables that control the Url and Atlas Cluster that will be used. If the BAAS_URL environment variable is not set, no apps will be imported and sync tests will not run. (PR #309)

realm.write(() => realm.add(team));

var firstCall = true;
final subscription = team.players.changes.listen((changes) {
changes.inserted // indexes of inserted ojbects
changes.modified // indexes of modified objects
changes.deleted  // indexes of deleted objects
changes.newModified // indexes of modified objects after deletions and insertions are accounted for.
changes.moved // indexes of moved objects
});

subscription.cancel(); // cancel the subscription

  • Support change notifications on realm objects. (#262)
