error message after using notifier 1.0.2 plugin in flutter - flutter

Question

I was looking for an alternative for Broadcast receiver in flutter then I got a plugin notifier 1.0.2 after adding to my pubspec.yaml getting an error message like
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
here is my pubspec.yaml

# Both the version and the builder number may be overridden in flutter

Answer 1

I solved my purpose by using event bus
Create an Event Bus
EventBus eventBus = EventBus();
Define Events (Create a class with event name with constructor)
class UserLoggedInEvent {
User user;
UserLoggedInEvent(this.user);
}
Register Listeners (Listen to your events)
eventBus.on<UserLoggedInEvent>().listen((event) {
// All events are of type UserLoggedInEvent (or subtypes of it).
print(event.user);
});
Fire your event
User myUser = User('Mickey');
eventBus.fire(UserLoggedInEvent(myUser));
cancel your all events
eventBus.cancel();
