【问题描述】:
我正在使用位置插件来获取设备的当前位置。但是,在某些设备上,await getLocation() 永远不会返回(调试控制台中也没有错误)。我该如何处理这样的问题?
这是我的 getCurrentLocation() 代码
import 'package:geolocator/geolocator.dart';
import 'location.dart';
/// Determine the current position of the device.
///
/// When the location services are not enabled or permissions
/// are denied the `Future` will return an error.
Future<Position> getCurrentLocation() async {
bool serviceEnabled;
LocationPermission permission;
Position position;
await reqLocation(); // requests turn on location
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).');
}
}
print('LOGIC');
position = await Geolocator.getCurrentPosition();
if (position == null) {
print('null');
} else {
print('LOCATION');
print(position);
}
return position;
}
