getLastKnownPosition method

Future<Position?> getLastKnownPosition()

Returns the last known location of the device or an error, if permissions don't suffice. Automatically queries user permission if possible

Implementation

Future<Position?> getLastKnownPosition() async {
  bool serviceEnabled;
  LocationPermission permission;

  // Test if location services are enabled.
  serviceEnabled = await Geolocator.isLocationServiceEnabled();
  if (!serviceEnabled) {
    // Location services are not enabled don't continue
    // accessing the position and request users of the
    // App to enable the location services.
    return Future.error('Location services disabled');
  }

  permission = await Geolocator.checkPermission();
  if (permission == LocationPermission.denied) {
    permission = await Geolocator.requestPermission();
    if (permission == LocationPermission.denied) {
      // Permissions are denied, next time you could try
      // requesting permissions again (this is also where
      // Android's shouldShowRequestPermissionRationale
      // returned true. According to Android guidelines
      // your App should show an explanatory UI now.
      return Future.error('Location permissions denied');
    }
  }

  if (permission == LocationPermission.deniedForever) {
    // Permissions are denied forever, handle appropriately.
    return Future.error('Location permissions permanently denied');
  }

  // When we reach here, permissions are granted and we can
  // continue accessing the last known position of the device.
  return await Geolocator.getLastKnownPosition();
