Geolocator 包不起作用，Flutter

Question

I am trying to get the current geolocation in Flutter using the Geolocator package but it's not working. Here is my function code:

local() async {
  final Geolocator geolocator = Geolocator()..forceAndroidLocationManager = true;

  var position = await geolocator.getCurrentPosition(desiredAccuracy: LocationAccuracy.low);

  print(position);
}

It's printing NULL.

Note : I have set the proper permissions in AndroidManifest along with the geolocator API key.

Geolocator package version : 5.3.0

Flutter Doctor: (I can't use the last version of flutter currently)

Doctor summary (to see all details, run flutter doctor -v):

Answer 1

Didn't find the problem with the Geolocator package, so i used the Locator package and it worked fine.

Here's my function :

import 'package:location/location.dart';

LocationData locationData;

local() async {
    Location location = new Location();

    locationData = await location.getLocation();
    print(locationData);
  }
