О пакете Flutter GeoLocator

Question

надеюсь, у вас все хорошо. Я столкнулся с проблемой, касающейся карт Google во флаттере. Я использую Flutter Google Maps. И GeoLocator Package of Flutter. Проблема в том, что пакет geolocator не выполняет поиск во многих местах на картах Google, а скорее выдает ошибку Ошибка при поиске местоположений

Мой код указан ниже,

import 'package:flutter/material.dart';
import 'package:google_maps_flutter/google_maps_flutter.dart';
import 'package:geolocator/geolocator.dart';
import 'package:geocoder/geocoder.dart';
void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      debugShowCheckedModeBanner: false,
      home: LocationScreen(),
    );
  }
}

class LocationScreen extends StatefulWidget {
  final Key _mapKey = UniqueKey();
  @override
  _MyHomePageState createState() => _MyHomePageState();
}

class _MyHomePageState extends State<LocationScreen> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
        appBar: AppBar(title: const Text('Map not crashing demo')),
        body: TheMap(key: widget._mapKey));
  }
}

class TheMap extends StatefulWidget {
  TheMap({@required Key key}) : super(key: key);
  @override
  _TheMapState createState() => _TheMapState();
}

class _TheMapState extends State<TheMap> {
  GoogleMapController mapController;
  final Set<Marker> _markers = {};
  String searchAddr;
 // CLASS MEMBER, MAP OF MARKS
Future<List<Placemark>> currentLocation;
  double lati = 40.7128;
  double longi = -74.0060;
  String newLocation;
  var first;
  String updatedLocation;
  List<Marker> allMarkers = [];
  @override
  void initState() {
    // TODO: implement initState
    super.initState();
    currentLocation =
        Geolocator().placemarkFromCoordinates(40.7128, -74.0060);
