import 'package:geolocator/geolocator.dart';

class _HomeState extends State<Home> {
  final Geolocator geolocator = Geolocator()..forceAndroidLocationManager;
  Position  _currentPosition;
  String _currentAddress;

  void initState() {
    super.initState();
    getCurrentLocation();
  }

getCurrentLocation() {
    geolocator
      .getCurrentPosition(desiredAccuracy: LocationAccuracy.best)
      .then((Position position) {
         setState(() {
          _currentPosition = position;
          getAddressFromLatLng();
        });
      })
      .catchError((e) {

      });
  }

  getAddressFromLatLng() async {
    try {
      List<Placemark> p = await geolocator.placemarkFromCoordinates(
          _currentPosition.latitude, _currentPosition.longitude);

      Placemark place = p[0];

      setState(() {
        _currentAddress =
        "${place.locality}, ${place.postalCode}, ${place.country}";
      });
    } catch (e) {

    }
  }
}
