Android - requestPermission not asking for permission

Describe the bug When calling location.requestPermission(), Android does not ask for permission

Expected behavior A popup should appears, asking for permission

Tested on:

• OnePlus 6 (Android 9)
• Pixel XL Emulator (API 28)

Additional logs

Exception has occurred. PlatformException (PlatformException(PERMISSION_DENIED_NEVER_ASK, Location permission denied forever- please open app settings, null))

I also created this thread on Stackoverflow.

Future<LocationData> _getLocation() async {
  LocationData currentLocation;

  var test = await location.requestPermission();

  try {
    currentLocation = await location.getLocation();
  } catch (e) {
    currentLocation = null;
  }
  return currentLocation;
}

When I go to the app Settings on my OP6, the permissions is greyed out, saying “no permissions requested”
