Constructors

Store(ModelDefinition modelDefinition, {String? directory, int? maxDBSizeInKB, int? maxDataSizeInKB, int? fileMode, int? maxReaders, int? debugFlags, bool queriesCaseSensitiveDefault = true, String? macosApplicationGroup})
Creates a BoxStore using the model definition from your objectbox.g.dart file in the given directory path (or if null the defaultDirectoryPath).
Store.attach(ModelDefinition modelDefinition, String? directoryPath, {bool queriesCaseSensitiveDefault = true})
Attach to a store opened in the directoryPath (or if null the defaultDirectoryPath).
Store.fromReference(ModelDefinition modelDefinition, ByteData _reference, {bool queriesCaseSensitiveDefault = true})
Create a Dart store instance from an existing native store reference.

Properties

directoryPath String
Path to the database directory.
no setter
hashCode int
The hash code for this object.
no setterinherited
reference ByteData
Returns a store reference you can use to create a new store instance with a single underlying native store. See Store.fromReference for more details.
no setter
runtimeType Type

Methods

awaitQueueCompletion() bool
Await for all (including future) submissions using Box.putQueued to be completed (the queue becomes idle for a moment).
awaitQueueSubmitted() bool
Await for previously submitted operations using Box.putQueued to be completed (the queue does not have to become idle).
box<T>() Box<T>
Returns a cached Box instance.
close() → void
Closes this store.
isClosed() bool
Returns if this store is already closed and can no longer be used.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
runAsync<P, R>(RunAsyncCallback<P, R> callback, P param) Future<R>
Spawns an isolate, runs callback in that isolate passing it param with its own Store and returns the result of callback.
runInTransaction<R>(TxMode mode, R fn()) → R
Executes a given function inside a transaction. Returns fn's result. Aborts a transaction and rethrows on exception if fn is asynchronous.
runInTransactionAsync<R, P>(TxMode mode, TxAsyncCallback<R, P> callback, P param) Future<R>
Like runAsync, but executes callback within a read or write transaction depending on mode.
syncClient() SyncClient?
Return an existing SyncClient associated with the store or null if not available. Use Sync.client() to create one first.
toString() String
A string representation of this object.

Operators

operator ==(Object other) bool
The equality operator.

Static Properties

debugLogs bool
Enables a couple of debug logs. This meant for tests only; do not enable for releases!
getter/setter pair

Static Methods

dbFileSize(String? directoryPath) int
Returns the file size in bytes of the main database file for the given directoryPath, or 0 if the file does not exist or some error occurred.
isOpen(String? directoryPath) bool
Returns if an open store (i.e. opened before and not yet closed) was found for the given directoryPath.
removeDbFiles(String? directoryPath) → void
Danger zone! This will delete all files in the given directory!

Constants

defaultDirectoryPath → const String
Path of the default directory, currently 'objectbox'.
inMemoryPrefix → const String
Pass this together with a String identifier as the directory path to use a file-less in-memory database.
