Turn on location services without navigating to settings page ? Flutter Dart

问题

We are migrating from to Flutter. We used this thread to Turn on location services without navigating to settings page

How can this be achieved in Flutter?

The current temporary code that navigates to settings:

  Future _getCurrentLocation() async {
    Position position;
    try {
      position = await Geolocator().getCurrentPosition(
          desiredAccuracy: LocationAccuracy.bestForNavigation);
    } on PlatformException catch(e){
      print(e.code);
      if(e.code =='PERMISSION_DISABLED'){
        print('Opening settings');
        await openLocationSetting();
        try {
          position = await Geolocator().getCurrentPosition(
              desiredAccuracy: LocationAccuracy.bestForNavigation);
        } on PlatformException catch(e){
          print(e.code);
        }
      }
    }

    setState(() {
//      _center = LatLng(currentLocation['latitude'], currentLocation['longitude']);
      _center = LatLng(position.latitude, position.longitude);
    });
  }
  Future openLocationSetting() async {
    final AndroidIntent intent = new AndroidIntent(
      action: 'android.settings.LOCATION_SOURCE_SETTINGS',
    );
    await intent.launch();

  }

You can use the location package, you just have to add the required permissions in your AndroidManifest.xml and Info.plist files, permission will be asked in a pop-up.
