drift 1.6.0

Drift is a reactive library to store relational data in Dart and Flutter applications.

1.6.0

• Add the unique() method to columns and the uniqueKeys override to tables to define unique constraints in Dart tables.
• Add the check() method to the Dart column builder to generate CHECK column constraints.
• Also apply type converters for json serialization and deserialization if they mix in JsonTypeConverter.
• Add the very experimental package:drift/wasm.dart library. It uses WebAssembly to access sqlite3 without any external JavaScript libraries, but requires you to add a WebAssembly module to the web/ folder. Please note that this specific library is not subject to semantic versioning until it leaves its experimental state. It also isn't suitable for production use at the moment.
• Internally use package:js to wrap sql.js.

1.5.0

• Add DataClassName.extending to control the superclass of generated row classes.
• Add setup parameter to the constructors of WebDatabase too.
• Don't write variables for expressions in CREATE VIEW statements.
• Improve stack traces for errors on a remote isolate.
• Add MultiExecutor.withReadPool constructor to load-balance between multiple reading executors. This can be used in a multi-isolate approach if some queries are expensive.

1.4.0

• Most methods to compose statements are now available as an extension on tables. As an alternative to update(todos).replace(newEntry), you can now write todos.replaceOne(newEntry).
• Deprecate the from(table) API introduced in 1.3.0. Having the methods on the table instances turned out to be even easier!
• In drift files, you can now use LIST(SELECT ...) as a result column to get all results of the inner select as a List in the result set.

1.3.0

• Add the from(table) method to generated databases. It can be used to write common queries more concisely.
• Make groupConcat nullable in the Dart API.
• Throw an exception in a NativeDatabase when multiple statements are run in a single call. In previous versions, parts of the SQL string would otherwise be ignored.
• Close the underlying database when a drift isolate is shut down.

1.2.0

• Properly support stream update queries on views.
• Reading blobs from the database is more lenient now.
• Provide a stack trace when getSingle() or watchSingle() is used on a query emitting more than one row.

1.1.1

• Rollback transactions when a commit fails.
• Revert a change from 1.1.0 to stop serializing messages over isolates. Instead, please set the serialize parameter to false on the DriftIsolate methods.

1.1.0

• Add the references method to BuildColumn to reference a column declared in another Dart table.
• Add the generateInsertable option to @UseRowClass. When enabled, the generator will emit an extension to use the row class as an Insertable. Thanks to @westito.
• Allow the generator to emit correct SQL code when using arrays with the new_sql_code_generation option in specific scenarios.
• Add support for strict tables in .drift files.
• Add the generatedAs method to declare generated columns for Dart tables.
• Add OrderingTerm.random to fetch rows in a random order.
• Improved support for pausing query stream subscriptions. Instead of buffering events, query streams will suspend fetching data if all listeners are paused.
• Drift isolates no longer serialize messages into a primitive format. This will reduce the overhead of using isolates with Drift.

1.0.1

• Add DoUpdate.withExcluded to refer to the excluded row in an upsert clause.
• Add optional where clause to DoUpdate constructors

This is the initial release of the drift package (formally known as moor). For an overview of old moor releases, see its changelog.
