title: Flutter Firebase Cloud Messaging - Notification when app in background
body: <p>I am currently using FCM for push notifications. When my app is open, I receive the notification, however when the app is closed or in the background - I do not receive anything until I reopen the app. On XCode, I have background fetch enabled and remote notifications enabled. What should I check next? Thank you.</p>
  
  <p>I am using <code>firebase_messaging: ^5.1.6</code></p>
  
  <p>with the code</p>
  
  <pre><code>    _firebaseMessaging.configure(
        onMessage: (Map&lt;String, dynamic&gt; message) async {
          print('message is $message');
  
          setState(
            () {
              showOverlayNotification((context) {
                return GestureDetector(
                  onTap: () {},
                  child: Platform.isIOS
                      ? MessageNotification(
                          title: message['notification']['title'],
                          body: message['notification']['body'],
                        )
                      : MessageNotification(
                          title: message['notification']['title'],
                          body: message['notification']['body'],
                        ),
                );
                // }
              }, duration: Duration(milliseconds: 4000));
            },
          );
        },
        onLaunch: (Map&lt;String, dynamic&gt; message) async {
          print('launching');
        },
        onResume: (Map&lt;String, dynamic&gt; message) async {
          print('resuming');
          print("onResume: $message");
        },
      );
      _firebaseMessaging.requestNotificationPermissions(
          const IosNotificationSettings(sound: true, badge: true, alert: true));
      _firebaseMessaging.onIosSettingsRegistered
          .listen((IosNotificationSettings settings) {
        print("Settings registered: $settings");
      });
      _firebaseMessaging.getToken().then((String token) {
        assert(token != null);
        setState(() {
          _firebaseMessaging.subscribeToTopic('all');
          print('subscribed');
          _homeScreenText = "Push Messaging token: $token";
          _saveDeviceToken(token);
        });
        print(_homeScreenText);
      }); ```
