JSideEffectHandler<T extends JState> class abstract

Handles side effects emitted by a JController.

JSideEffectHandler provides a mechanism to map side effect types to their corresponding handling logic. It connects the controller and the current UI BuildContext to process effects in a centralized, maintainable way.

Typically used within a widget to listen to the controller’s sideEffects stream.

Example usage:

final handler = MyEffectHandler(controller, context);
handler.register<ShowDialogEffect>((effect, controller) async {
  final confirmed = await showDialog(...);
  effect.complete(confirmed);
});
