Flutter - 获取城市名称

Question

如何知道flutter中的城市名称？我用了这么多包，只得到了Lang和Lat 我想得到城市名称！ 有什么包可以帮助我解决这个问题吗？

import 'package:flutter_material_pickers/flutter_material_pickers.dart';
import 'package:random_color/random_color.dart';
import 'package:location/location.dart';
import 'package:geocoder/geocoder.dart';

class _ProfileScreenState extends State<ExploreScreen> {
  final GlobalKey<ScaffoldState> _scaffoldKey = new GlobalKey<ScaffoldState>();
  String cityName = ksaCities[29];
  double userLongitude;
  double userLatitude;
  int page = 0;

  @override
  initState() {
    super.initState();
    getCurrentLocation();
  }

  Future<Address> getCurrentLocation() async {
    LocationData myLocation;
    String error;
    Location location = new Location();
    try {
      myLocation = await location.getLocation();
    } on PlatformException catch (e) {
      if (e.code == 'PERMISSION_DENIED') {
        error = 'please grant permission';
        print(error);
      }
      if (e.code == 'PERMISSION_DENIED_NEVER_ASK') {
        error = 'permission denied- please enable it from app settings';
        print(error);
      }
      myLocation = null;
    }
    final coordinates =
        new Coordinates(myLocation.latitude, myLocation.longitude);
    var addresses =
        await Geocoder.local.findAddressesFromCoordinates(coordinates);
    var first = addresses.first;
    print(
        ' ${first.locality}, ${first.adminArea},${first.subLocality}, ${first.subAdminArea},${first.addressLine}, ${first.featureName},${first.thoroughfare}, ${first.subThoroughfare}');
    return first;
  }
}

使用geocoder 这可以帮助您获取当前位置（纬度、经度、城市、国家名称、地址等）

import 'package:location/location.dart';
 import 'package:geocoder/geocoder.dart';
 import 'package:flutter/services.dart';

getUserLocation() async {

      LocationData myLocation;
      String error;
      Location location = new Location();
      try {
        myLocation = await location.getLocation();
      } on PlatformException catch (e) {
        if (e.code == 'PERMISSION_DENIED') {
          error = 'please grant permission';
          print(error);
        }
        if (e.code == 'PERMISSION_DENIED_NEVER_ASK') {
          error = 'permission denied- please enable it from app settings';
          print(error);
        }
        myLocation = null;
      }
      currentLocation = myLocation;
      final coordinates = new Coordinates(
          myLocation.latitude, myLocation.longitude);
      var addresses = await Geocoder.local.findAddressesFromCoordinates(
          coordinates);
      var first = addresses.first;
      print(' ${first.locality}, ${first.adminArea},${first.subLocality}, ${first.subAdminArea},${first.addressLine}, ${first.featureName},${first.thoroughfare}, ${first.subThoroughfare}');
      return first;
    }
