I am learning Flutter and trying to rebuild Clima project following londonappbrewery's flutter course. After I installed the geolocator package and invoked the getCurrentPosition method, I got nothing.

The geolocator version is ^9.0.2 with flutter 3.10.6 and I'm testing on a physical device.

geolocator package problem

void getLocation() async {
    LocationPermission permission = await Geolocator.requestPermission();
    print(permission);
    Position position = await Geolocator.getCurrentPosition(desiredAccuracy: LocationAccuracy.low);
    print(position);
}

I manually asked permission from the device, but it's still not working.

This is what I add to the AndroidManifest.xml file:

<uses-permission android:name="android.permission.ACCESS_BACKGROUND_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />

You need to also check the Location Service status. Try this code:

Future<Position> determinePosition() async {
  final serviceEnabled = await Geolocator.isLocationServiceEnabled();

  if (!serviceEnabled) {
    return Future.error('Location service is disabled.');
  }

  var permission = await Geolocator.checkPermission();

  if (permission == LocationPermission.denied) {
    permission = await Geolocator.requestPermission();
    if (permission == LocationPermission.deniedForever) {
      return Future.error('Location permission is denied forever.');
    }
    if (permission == LocationPermission.denied) {
      return Future.error('Location permission is denied.');
    }
  }

  return Geolocator.getCurrentPosition(
    desiredAccuracy: LocationAccuracy.low,
  );
}

And change your permissions in AndroidManifest.xml to:

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

With ACCESS_COARSE_LOCATION only it might take a long time (minutes) before you will get your first locations fix.

If this doesn't help, check that all the rest plugin's requirements for Android are met.

    The link does work. I re-config my project according to the link you provided and re-factor my method to check the permission first and manually get permission like this `void getLocation () async { LocationPermission permission = await Geolocator.checkPermission(); if(permission == LocationPermission.denied) { print('Permission denied!'); permission = await Geolocator.requestPermission(); } Position location = await Geolocator.getCurrentPosition(); print(location.latitude); }` All good now.
