Tried on many diffrent devices same result.

Post your code

basic headless setup.

it works btw. but i can see that error in debug logs.

BackgroundGeolocation.registerHeadlessTask(headlessTask);

@pragma('vm:entry-point')
void headlessTask(bg.HeadlessEvent headlessEvent) async {
  await Firebase.initializeApp(
    options: DefaultFirebaseOptions.currentPlatform,
  ).then((value) => print('Firebase initialized'));
  String uid = FirebaseAuth.instance.currentUser!.uid;
  print('[BackgroundGeolocation HeadlessTask]: $headlessEvent');
  // Implement a 'case' for only those events you're interested in.
  switch (headlessEvent.name) {
    case bg.Event.TERMINATE:
      bg.State state = headlessEvent.event;
      print('- State: $state');
      break;
    case bg.Event.HEARTBEAT:
      bg.HeartbeatEvent event = headlessEvent.event;
      print('- HeartbeatEvent: $event');
      break;
    case bg.Event.LOCATION:
      bg.Location location = headlessEvent.event;
      print('- Location: $location');
      LocationData locationData = Utils.bgLocationToLocationData(location);
      FirebaseService.addLocationData(locationData, uid);
      print("Firebase data added");
      break;
    case bg.Event.MOTIONCHANGE:
      bg.Location location = headlessEvent.event;
      print('- Location: $location');
      break;
    case bg.Event.GEOFENCE:
      bg.GeofenceEvent geofenceEvent = headlessEvent.event;
      print('- GeofenceEvent: $geofenceEvent');
      break;
    case bg.Event.GEOFENCESCHANGE:
      bg.GeofencesChangeEvent event = headlessEvent.event;
      print('- GeofencesChangeEvent: $event');
      break;
    case bg.Event.SCHEDULE:
      bg.State state = headlessEvent.event;
      print('- State: $state');
      break;
    case bg.Event.ACTIVITYCHANGE:
      bg.ActivityChangeEvent event = headlessEvent.event;
      print('ActivityChangeEvent: $event');
      FirebaseService.addActivityData(event, uid);
      break;
    case bg.Event.HTTP:
      bg.HttpEvent response = headlessEvent.event;
      print('HttpEvent: $response');
      break;
    case bg.Event.POWERSAVECHANGE:
      bool enabled = headlessEvent.event;

      print('ProviderChangeEvent: $enabled');
      break;

    case bg.Event.ENABLEDCHANGE:
      bool enabled = headlessEvent.event;
      print('EnabledChangeEvent: $enabled');
      break;
  }
}

   bg.BackgroundGeolocation.onLocation((bg.Location location) {
      print('[location]  - $location');
      FirebaseService.addLocationData(Utils.bgLocationToLocationData(location),
          FirebaseAuth.instance.currentUser!.uid);
    });

    // Configure BackgroundGeolocation.
    bg.BackgroundGeolocation.ready(bg.Config(
            debug: true,
            reset: true,

I suggest you review the Android Setup docs and ensure you've completed every item in the doc.

[mfurkanyuceal]

Same problem, I'm pretty sure I followed all the steps in the Android setup.

[christocracy]

I think I see the problem. The plugin is using reflection and composing method-names via String concatenation.

While capitalizing the property name isMoving to method-name setIsMoving, the capitalization on the I in isMoving looks to generate an unexpected character where the capital I has a dot above it. It must be related to the Locale on the device.

setİsMoving

This is supposed to be:

setIsMoving

These exceptions are caught and should not cause a crash. I will look into enforcing en-US when performing String.toUppercase on the letter i.
