Code sample

Code sample

      locationSettings = AndroidSettings(
          accuracy: LocationAccuracy.high,
          // distanceFilter: 3,
          forceLocationManager: true,
          intervalDuration: const Duration(seconds: 1),
          //(Optional) Set foreground notification config to keep the app alive
          //when going to the background
          foregroundNotificationConfig:
          const ForegroundNotificationConfig(
            notificationText:
            "App will continue to receive your location even when you are in Background.",
            notificationTitle: "Running in Background",
            notificationIcon: AndroidResource(name: 'ic_launcher', defType: 'mipmap'),
            enableWakeLock: true,
            enableWifiLock: true,
            setOngoing: true
          )
      );


    positionStream = Geolocator.getPositionStream(locationSettings: locationSettings).listen(
            (Position? position) {
              if (position?.isValid ?? false) {
                this.position = position!;
                position.saveLocation();
              }
              if (kDebugMode) print(position?.toJson());

Can you reproduce this in the example app too?

Kind regards,

[gujjar1988]

@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 call `initializeApp` before using other Firebase services.

  // await Firebase.initializeApp(options: DefaultFirebaseOptions.currentPlatform);

  if (kDebugMode) print("Handling a background message: ${message.messageId}");
  if (Platform.isAndroid) {
    String type = message.data['type'];
    if (type.isNotEmpty) {
      final SharedPreferences prefs = await SharedPreferences.getInstance();
      List<String> savedList = prefs.getStringList(StorageEnum.backgroundRemoteMessage.name) ?? [];
      savedList.add(type);
      await prefs.setStringList(StorageEnum.backgroundRemoteMessage.name, savedList);
      if (kDebugMode) print("${message.messageId} saved in DB.");
    }


  } else {
    message.checkAction();
  }
}

I Have exacly the same issue

[TimHoogstrate]

@menezes85,

Can you share detailed steps to reproduce?

Kind regards,

[menezes85]

Hello, @TimHoogstrate I believe that this problem is related to the life cycle of the application, probably there must be some call native to onDestroy for the flutter that is not managing to be delivered and is therefore being imprisoned in the execution pile. I have a similar problem in my app and removing this call from onDestroy was solved, basically when the application is killed, flutter engine becomes detatched and the methodChannel can no longer be accessed. Just start app, and make some calls to geolocator and close, the issue will happen on console
