这是我的代码，

    class FirebaseNotifications {
       FirebaseMessaging _firebaseMessaging;
       SharedPreferences _sharedPreferences;

       void setUpFirebase() {
         _firebaseMessaging = FirebaseMessaging();
         initializeSharedPreferences();
         firebaseCloudMessaging_Listeners();
        }

        void initializeSharedPreferences() async {
        _sharedPreferences = await SharedPreferences.getInstance();
        }

        void firebaseCloudMessaging_Listeners() {
        if (Platform.isIOS) iOS_Permission();
        _firebaseMessaging.getToken().then((token) {
        _sharedPreferences.setString(Preferences.device_token, token);
         print('Token'+token);
         });

         _firebaseMessaging.configure(
          onMessage: (Map<String, dynamic> message) async {
          print('on message $message');
         },
          onResume: (Map<String, dynamic> message) async {
          print('on resume $message');
         },
         onLaunch: (Map<String, dynamic> 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");
    });
   }
  }

推荐答案

在这个问题上您并不孤单-尝试

You are not alone in this problem - try this solution.

还要检查它是否不能同时在应用程序的调试版本和发行版本中使用-应用程序的调试版本可能无法解析通知.

Also, check if it not working both on debug and release builds of the application - there is a possibility of notifications not parsed by the debug variant of app.
