在 flutter 中使用 notifier 1.0.2 插件后的错误信息
error message after using notifier 1.0.2 plugin in flutter
我在 flutter 中寻找 Broadcast receiver
的替代品,然后我得到了一个插件 notifier 1.0.2
添加到我的 pubspec.yaml
后收到一条错误消息,如
Because every version of notifier depends on synchronized ^1.5.3+2 and sqflite 1.2.0 depends on synchronized >=2.0.2 <4.0.0, notifier is incompatible with sqflite 1.2.0.
So, because Bluis depends on both sqflite 1.2.0 and notifier 1.0.2, version solving failed.
pub get failed (1; So, because Bluis depends on both sqflite 1.2.0 and notifier 1.0.2, version solving failed.)
Process finished with exit code 1
这是我的 pubspec.yaml

我使用 event bus
解决了我的目的
创建事件总线
EventBus eventBus = EventBus();
定义事件(用构造函数创建一个 class 事件名称)
class UserLoggedInEvent {
User user;
UserLoggedInEvent(this.user);
}
注册监听器(监听你的事件)
eventBus.on<UserLoggedInEvent>().listen((event) {
// All events are of type UserLoggedInEvent (or subtypes of it).
print(event.user);
});
启动您的活动
User myUser = User('Mickey');
eventBus.fire(UserLoggedInEvent(myUser));
取消所有活动
eventBus.cancel();
