Hey @chiennv23 could you add more explanation on what you do exactly ? 🙂

HI @raymondk25 this seems to be an issue with your background handler not firing instead of the library.

Try adding content-available: true for iOS and priority: high for android as a part of your FCM message from your server.

const message: Message = {
            notification: {
                title: "Test notification",
                body: 'test content',
            },
            data: {
               // notification data here
            },
            token: deviceToken,
            android: {
                priority: 'high',
            },
            apns: {
                payload: {
                    aps: {
                        contentAvailable: true,
                    },
                },
            },
        }

@rohanddave I tried to set contentAvailable: true on iOS, but the app was still not updated when the app was closed.
Do you have another solution to fix it?

from flutter_app_badger.

@ProFive you need to ensure your background handler function is a static or top level function since flutter runs on an Isolate in the background. Additionally, I would check XCode to ensure Background Processing, Background Fetch and Remote Notifications are selected under Background Modes. Also, check if you have Push Notifications enabled in XCode too

from flutter_app_badger.

Hi @rohanddave

Main.dart @pragma('vm:entry-point') Future<void> _firebaseMessagingBackgroundHandler(RemoteMessage message) async { // If you're going to use other Firebase services in the background, such as Firestore, // make sure you callinitializeAppbefore using other Firebase services. await Firebase.initializeApp(); // print('A background message just showed up : $message'); int count = (SpUtil.getInt(PREF_APP_BADGER, defValue: 0) ?? 0) + 1; // print("A background message PREF_APP_BADGER count:$count"); FlutterAppBadger.updateBadgeCount(count); SpUtil.putInt(PREF_APP_BADGER, count); }
Xcode: I checked
Background fetch Remote notification Background processing

AppDelegate
@UIApplicationMain @objc class AppDelegate: FlutterAppDelegate { override func application( _ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]? ) -> Bool { if #available(iOS 10.0, *) { UNUserNotificationCenter.current().delegate = self as? UNUserNotificationCenterDelegate } GeneratedPluginRegistrant.register(with: self) return super.application(application, didFinishLaunchingWithOptions: launchOptions) } }

Hi @ProFive can you try putting FirebaseMessaging.onBackgroundMessage(handleBackgroundNotification); in your app's initState method where handleBackgroundNotification is a top level function i.e. not nested inside any class

@ProFive Did you manage to solve the issue?
