registerSubscribers function

@Deprecated('Use EventServiceProvider to register subscribers instead') void registerSubscribers(List<EventSubscriberInterface> subscribers, [ EventSystemInterface? eventSystem ])

Utility for registering event subscribers with the global event system.

This function provides a convenient way to register multiple event subscribers at once, automatically registering all their event handlers with the global event bus. It's typically used during application initialization to set up all event-driven components.

The function iterates through each subscriber and registers all their event handlers using the global Khadem event bus. Each handler is registered with its specified priority and one-time execution settings.

Example usage:

class UserEventHandler implements EventSubscriberInterface {
  @override
  List<EventMethod> getEventHandlers() => [
    EventMethod(
      eventName: 'user.created',
      handler: (user) async => print('User created: $user'),
      priority: EventPriority.normal,
    ),
  ];
}

// Register the subscriber
registerSubscribers([UserEventHandler()]);

subscribers - A list of event subscriber instances to register eventSystem - Optional event system instance to use (defaults to global Khadem event bus)
