LifecycleHooksStateMixin<T extends StatefulWidget> mixin

Mixin providing lifecycle hooks for State classes.

Extends LifecycleCallbacks with Flutter lifecycle method overrides that automatically run registered callbacks at the correct times.

class _MyState extends State<MyWidget>
    with LifecycleCallbacks, LifecycleHooksStateMixin {
  @override
  void initState() {
    super.initState();
    onMounted(() => print('Mounted!'));
    onDispose(() => print('Disposing...'));
  }
}
