flutter定位简单工具类

import 'package:permission_handler/permission_handler.dart';class PermissionUtil {/// 获取用户定位权限static Future<bool> getLocationStatus() async {Map<Permission, PermissionStatus> statuses = await [Permission.location,].request();return statuses[Permission.location].isGranted;}//判断是否已经获取了位置权限授权static Future<bool> judgeLocationAuth() async {var status = await Permission.locationWhenInUse.status;if (status == PermissionStatus.granted) {return true;}else {return false;}}//判断手机是否开启了定位服务static Future<bool> serviceEnabled() async {bool serviceEnabled = await Geolocator.isLocationServiceEnabled();return serviceEnabled;}//1.获取位置信息
Future<Position> _determinePosition() async {bool serviceEnabled;LocationPermission permission;//判断手机是否开启定位服务serviceEnabled = await Geolocator.isLocationServiceEnabled();//位置服务是否启用if (!serviceEnabled) {return Future.error('Location services are disabled.');}//获取位置位置权限/*bool locationAuth = await _locationAuthDialog();if(locationAuth){}*/permission = await Geolocator.checkPermission();if (permission == LocationPermission.denied) {permission = await Geolocator.requestPermission();if (permission == LocationPermission.denied) {return Future.error('Location permissions are denied');}}//位置权限是否永久拒绝if (permission == LocationPermission.deniedForever) {return Future.error('Location permissions are permanently denied, we cannot request permissions.');}return await Geolocator.getCurrentPosition(desiredAccuracy: LocationAccuracy.best,forceAndroidLocationManager: true);}//2.从经纬度编码成地址
getAddressFromLatLng() async{Position position = await _determinePosition();print('纬度：${position.latitude}   经度：${position.longitude} ');List<Placemark> placeMark = await placemarkFromCoordinates(position.latitude, position.longitude);print('地址：${placeMark[0].administrativeArea} ${placeMark[0].locality}  ${placeMark[0].subLocality} ${placeMark[0].subAdministrativeArea} ${placeMark[0].thoroughfare} ${placeMark[0].subThoroughfare} ${placeMark[0].name} ${placeMark[0].name}');CommonConfig.lat = position.latitude;CommonConfig.lng = position.longitude;CommonConfig.currentCityName = placeMark[0].locality;return {"provinceName": placeMark[0].administrativeArea,"cityName": placeMark[0].locality,"districtName": placeMark[0].subLocality,};}}
