Effect

The @SolidEffect() annotation will trigger a side effect whenever the reactive state variables it depends on change.

Usage

source/effect_example.dart

class EffectExample extends StatelessWidget {
  EffectExample({super.key});

  @SolidState()
  int counter = 0;

  @SolidEffect()
  void logCounter() {
    print('Counter changed: $counter');
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(title: const Text('Effect')),
      body: Center(child: Text('Counter: $counter')),
      floatingActionButton: FloatingActionButton(
        onPressed: () => counter++,
        child: const Icon(Icons.add),
      ),
    );
  }
}
