Flutter-地理位置上的java.lang.IllegalStateException

问题描述

我的项目上有此类，该类返回设备的位置。当我在android模拟器上运行它时，获取当前位置没有问题，而且当我使用具有双SIM卡的其他物理设备时也是如此。但是，当我在具有双SIM卡网络的RedMi Note 7上运行它时，它不起作用，我尝试禁用其他SIM卡，重新启动了手机，而且我已经开启和关闭了飞行模式，但只能运行一次，我不知道是什么问题。我还看到了使用ADB logcat的异常。见下文

class LocationService {
  final DialogService _dialogService = locator<DialogService>();
  Position _currentPos;
  Position get currentPos => _currentPos;
  Geolocator geolocator = Geolocator()..forceAndroidLocationManager = true;
  Future getCurrentLocation() async {
    try {
      if(await Permission.location.isDenied || await Permission.location.isPermanentlyDenied || await     Permission.location.isRestricted ||await Permission.location.isUndetermined ) {
        await Permission.locationAlways.request();
        _currentPos = await geolocator.getCurrentPosition(desiredAccuracy: LocationAccuracy.best);
        print(_currentPos);
      } else {
        _currentPos = await geolocator.getCurrentPosition(desiredAccuracy: LocationAccuracy.best);
        print(_currentPos);
      }
    } catch (e) {
      await _dialogService.showDialog(
        title: 'Location Access Denied',description: 'You can turn on your device\'s location on your phone\'s settings.',);
      return null;
    }

  }

  void showToast(message) {
    Fluttertoast.showToast(
      msg: message,toastLength: Toast.LENGTH_SHORT,gravity: ToastGravity.BOTTOM,timeInSecForIosWeb: 1,backgroundColor: Colors.red,textColor: Colors.white,fontSize: 16.0,);
  }
}

使用ADB logcat的日志：
