Flutter geolocator， list 中没有定义位置权限。确保 list 中至少定义了 ACCESS_FINE_LOCATION 或....

Question

我在 flutter 中使用地理定位器，我在 list 文件中定义了权限，但它一直告诉我我没有。

list 文件:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="packagename">

   
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission>ACCESS_COARSE_LOCATION" />
    <uses-permission android:name="android.permission>ACCESS_FINE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_BACKGROUND_LOCATION" />

地理定位器代码:

class _LoadingScreenState extends State<LoadingScreen> {

  void getLocation() async{
    bool serviceEnabled;
    LocationPermission permission;

    serviceEnabled = await Geolocator.isLocationServiceEnabled();
    if (!serviceEnabled) {
      return Future.error('Location services are disabled.');
    }

    permission = await Geolocator.checkPermission();
    if (permission == LocationPermission.deniedForever) {
      return Future.error(
          'Location permissions are permantly denied, we cannot request permissions.');
    }

    if (permission == LocationPermission.denied) {
      permission = await Geolocator.requestPermission();
      if (permission != LocationPermission.whileInUse &&
          permission != LocationPermission.always) {
        return Future.error(
            'Location permissions are denied (actual value: $permission).');
      }
    }
    Position position= await Geolocator.getCurrentPosition(desiredAccuracy: LocationAccuracy.low);
    print(permission);
    print(position);
  }
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Center(
        child: RaisedButton(
          onPressed: (){
            getLocation();
          },
          child: Text('Get Location'),
        ),
      ),
    );
  }
}

我正在我的物理设备上测试该应用程序。请告诉我我应该怎么做才能让它发挥作用。

唯一错误的是“android.name”中的字符串。

<uses-permission android:name="android.permission>ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission>ACCESS_FINE_LOCATION" />

正确的是:

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
