ShakeTrigger class abstract

Unified trigger abstraction for shake animations.

ShakeTrigger is a lightweight interface used by ShakeContainer to listen for "shake events".

A shake is an event signal, not a UI state.

This makes it easy to integrate with different architectures, such as:

• ValueListenable / ChangeNotifier
• Stream-based systems (via StreamShakeTrigger)
• GetX / BLoC / Riverpod (through a custom trigger adapter)

Example (Stream)

final controller = StreamController<void>.broadcast();
final trigger = StreamShakeTrigger(controller.stream);

ShakeContainer(
  trigger: trigger,
  config: ShakePreset.error,
  child: const Text('Shake me'),
);

controller.add(null); // triggers shake

Notes:

• Each ShakeContainer should have its own ShakeTrigger.
• You should call dispose to release resources (e.g. stream subscriptions).
