$ flutter packages get

Now in your Dart code, you can use:

import 'package:firebase_messaging/firebase_messaging.dart';

Implementation:

FirebaseMessaging _firebaseMessaging = FirebaseMessaging();



@override
void initState() {
  super.initState();
  firebaseCloudMessaging_Listeners();
}

void firebaseCloudMessaging_Listeners() {
  if (Platform.isIOS) iOS_Permission();

  _firebaseMessaging.getToken().then((token){
    print(token);
  });

  _firebaseMessaging.configure(
    onMessage: (Map message) async {
      print('on message $message');
    },
    onResume: (Map message) async {
      print('on resume $message');
    },
    onLaunch: (Map message) async {
      print('on launch $message');
    },
  );
}

void iOS_Permission() {
  _firebaseMessaging.requestNotificationPermissions(
      IosNotificationSettings(sound: true, badge: true, alert: true)
  );
  _firebaseMessaging.onIosSettingsRegistered
      .listen((IosNotificationSettings settings)
  {
    print("Settings registered: $settings");
  });
}
