Versions 2.21.0 of drift and drift_dev as well as version 0.2.1 of drift_flutter have just been released:

Core changes

• View.from is now declared to return a JoinedSelectStatement, the type it returns at runtime.
• The manager APIs now support computed fields, allowing advanced SQL expressions to be embedded into simple manager queries.

Isolate improvements

• To infer whether serialization is required for inter-isolate communication, drift now sends a test message instead of serializing by default.
• drift_flutter: Enable serialization between background isolates where necessary.

Tooling and generator

• The DevTools extension can now clear drift databases.
• Fix Dart-defined check constraints not being considered in exported schemas.
• Columns can now be defined with late final fields. Defining columns with getters => is still supported too.

  class MyTable extends Table {
    // Before:
    IntColumn get id => integer().autoIncrement()();
  
    // After:
    late final id = integer().nullable()();
  }

• Make build.yaml definitions pass build_runner doctor.
• Fix generate_manager option not consistently being applied to modular builds.
• Add the make-migrations command which combines the existing schema commands into a single tool.
