EventPlugin class abstract

Base class for implementing event handling in Vyuh applications.

The event plugin provides a pub/sub system for decoupled communication between different parts of the application. It supports:

  • Event subscription with on and once
  • Event emission with emit
  • Automatic cleanup of event subscriptions

Example:

// Subscribe to events
final dispose = vyuh.event.on<UserLoggedInEvent>((event) {
  print('User ${event.data.userId} logged in');
});

// Emit events
vyuh.event.emit(UserLoggedInEvent(
  data: UserData(userId: '123'),
));

// Clean up subscription
dispose();
