MigrateSignalsMixinToSignalStatefulWidget

An IDE quick-fix refactoring tool (Dart Assist) that automatically migrates a deprecated SignalsMixin usage on a State class to extend the reactive SignalStatefulWidget instead.

:::important Since SignalsMixin is deprecated in signals v7, this automated quick-fix does two things:

1. Removes SignalsMixin from your State class's with clause.
2. Changes the parent widget class's superclass from StatefulWidget to SignalStatefulWidget. This results in a cleaner, highly optimized codebase that runs with zero unnecessary overhead. :::

How to use#

1. Place your cursor on the SignalsMixin name in the State's class signature.
2. Click the lightbulb icon or press your IDE's quick-fix shortcut (Alt+Enter or Cmd+.).
3. Select the Migrate SignalsMixin to SignalStatefulWidget assist option.

Examples#

Before:

class MyWidget extends StatefulWidget {
  const MyWidget({super.key});
  @override
  State<MyWidget> createState() => _MyWidgetState();
}

class _MyWidgetState extends State<MyWidget> with SignalsMixin { // LINT: Deprecated SignalsMixin
  @override
  Widget build(BuildContext context) {
    return Text('${counter.value}');
  }
}

After (Apply Assist):

class MyWidget extends SignalStatefulWidget {
  const MyWidget({super.key});
  @override
  State<MyWidget> createState() => _MyWidgetState();
}

class _MyWidgetState extends State<MyWidget> {
  @override
  Widget build(BuildContext context) {
    return Text('${counter.value}'); // OK
  }
}
