Steps to reproduce

1. Request permissions (Manifest contains both coarse and fine)
2. On device select to only share approximate location while in use (while in use might not be necessary)
3. When requesting the positions stream the app crashes: E/AndroidRuntime(23703): FATAL EXCEPTION: main E/AndroidRuntime(23703): Process: ro.a24assitance.app, PID: 23703 E/AndroidRuntime(23703): java.lang.SecurityException: Neither user 10473 nor current process has android.permission.ACCESS_FINE_LOCATION.

Expected results

Ideally we should be getting periodic updates from the approximate location.

Actual results

The app crashes.

Code sample

Code sample

if (await Geolocator.isLocationServiceEnabled()) {
      var permission = await Geolocator.checkPermission();
      if (permission == LocationPermission.denied || permission == LocationPermission.unableToDetermine) {
        permission = await Geolocator.requestPermission();
      }
      if (permission == LocationPermission.denied || permission == LocationPermission.deniedForever) {
        return;
      }
      final position = await Geolocator.getLastKnownPosition();
      if (position != null) {
        //handle position
      }
      _subscription = Geolocator.getPositionStream().listen(
        (position) {
          //handle position update
        },
      );
    } else {
      //no location
    }
