EventBus class

自定义事件总线

相当于iOS的NotificationCenter，用于发送事件通知和监听事件通知

使用示例:

EventBus().send(ThemeChangedEvent('follow system : darkTheme'));

订阅事件:

//发送事件
StreamSubscription<ThemeChangedEvent>? _subscription;

_subscription = EventBus().on<ThemeChangedEvent>().listen((event) {
  // 处理事件
  print('Received theme change event: ${event.theme}');
});
//取消订阅
_subscription.cancel();
