没有为“地理定位器”类型定义方法“placemarkFromCoordinates”

【中文标题】没有为“地理定位器”类型定义方法“placemarkFromCoordinates”

【英文标题】：The method 'placemarkFromCoordinates' isn't defined for the type 'Geolocator'

【问题描述】：

我正在尝试使用地标在我的颤振应用中获取用户位置。 我已经导入了运行应用程序所需的所有必要依赖项，但我仍然在地理定位器地标中遇到错误。我不知道该怎么办。

`import 'package:flutter/material.dart';

import 'package:flutter/widgets.dart';

import 'package:geolocator/geolocator.dart';

import 'package:google_maps_flutter/google_maps_flutter.dart';

import 'package:ft06/requests/google_maps_requests.dart';

class AppState with ChangeNotifier 

 static LatLng _initialPosition;

 LatLng _lastPosition = _initialPosition;

 bool locationServiceActive = true;

 final Set<Marker> _markers = ;

 final Set<Polyline> _polyLines = ;

 GoogleMapController _mapController;

 GoogleMapsServices _googleMapsServices = 

GoogleMapsServices();
 
TextEditingController locationController = 

TextEditingController();



 TextEditingController destinationController = 
TextEditingController();

 LatLng get initialPosition => _initialPosition;

 LatLng get lastPosition => _lastPosition;

 GoogleMapsServices get googleMapsServices => 
_googleMapsServices;

 GoogleMapController get mapController => 
_mapController;

 Set<Marker> get markers => _markers;

 Set<Polyline> get polyLines => _polyLines;



 AppState() 

   _getUserLocation();

   _loadingInitialPosition();

 

// ! TO GET THE USERS LOCATION

 void _getUserLocation() async 

   print("GET USER METHOD RUNNING =========");

   Position position = await Geolocator()

       .getCurrentPosition(desiredAccuracy:LocationAccuracy.high);

   List<Placemark> placemark = await Geolocator()

       .placemarkFromCoordinates(position.latitude, 
position.longitude);

   _initialPosition = LatLng(position.latitude, 
position.longitude);

   print("the latitude is: $position.longitude 
and th longitude is: $position.longitude ");

   print("initial position is : 




$_initialPosition.toString()");locationController.




text = placemark[0].name;




   notifyListeners();




 

actual error output terminal

请帮忙！！！

【参考方案1】：

从版本 6.0.0 开始，地标已从 geolocator 中删除并移至 geocoding。

将地理编码导入文件后使用

List<Placemark> placemarks = await placemarkFromCoordinates(position.latitude, position.longitude);
