Unhandled Exception: User denied permissions to access the device‘s location.

在写android app时，有的时候遇到这样的错误：未处理的异常:用户拒绝访问设备位置的权限。

即使加上了官网讲述的：下面两行代码任意一行，也不行。

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

 之前写的：

void getLocation() async {
    Position position = await Geolocator.getCurrentPosition(desiredAccuracy: LocationAccuracy.high);
    print(position);
}

 改为：

void getLocation() async {
    LocationPermission permission = await Geolocator.requestPermission();
    Position position = await Geolocator.getCurrentPosition(desiredAccuracy: LocationAccuracy.high);
    print(position);
}

也就是多加一行：

LocationPermission permission = await Geolocator.requestPermission();
