Ios – Flutter IOS FCM push notification not coming into notification bar

I am new to Flutter and IOS. I am configuring FCM push notifications for both Android and IOS.For android its working fine.I have done by referring this link https://medium.com/@jun.chenying/flutter-tutorial-part3-push-notification-with-firebase-cloud-messaging-fcm-2fbdd84d3a5e
. For IOS, if the app is opened and if I send FCM from Firebase Console at the same time , Flutter on message is called (See the screenshot , logs are there) . But if I close the app , notification is not coming to notification bar but I am receiving in Android App,
I don't know where is the problem , Problem with Apple Profiles or Flutter .

IOS Build Settings and Signing & Capabilities

Here is my code in flutter,

    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");
    });
   }
  }
