Update location in background?

I want to update user's location in background.

To perform tasks in background, i used this package, workmanager. Link to that: https://pub.dev/packages/workmanager

But i can not update the location, it seems like it can't work with async code?

here is my code,

void callbackDispatcher() {
  Workmanager.executeTask((task, inputData) async {
    await _HomeScreenState().updateUserLoc();
    print('it is working?');

    return Future.value(true);
  });
}
//Inside my stateFul Widget,



 void initState() {
    super.initState();
  
    
    Workmanager.initialize(
      callbackDispatcher,
      isInDebugMode: true,
    );

    Workmanager.registerPeriodicTask(
      "1",
      fetchBackground,
      frequency: Duration(minutes: 15),
    );
  }


updateUserLoc() async {
    print("executi9ng the updateUserLocccccc");
    await getusersLocation();
    print("executi9ng the updateUserLoc");
    GeoFirePoint point = geo.point(latitude: lat, longitude: long);
    _firestore.collection('locations').document(widget.userid).setData(
      {'position': point.data},
      merge: true,
    );
  }

Is there any other way of updating the users's location in background?

You have to call the call the code inside the updateUserLoc() directly inside the callbackDispatcher. Just make the callbackDispatcher async function.
