Flutter Geolocator Not returning any result

Question

I am currently using the latest geolocator that is 'geolocator: ^9.0.1'and for some reason am not able to get any data from the position function when i run

bool isLoc  = await Geolocator.isLocationServiceEnabled();
print(isLoc);

The result is true which i think means the location services are all enabled but when i run

Position position = await Geolocator.getCurrentPosition(desiredAccuracy: LocationAccuracy.best);
print('position');

nothing is been returned i have tried all the accuracy values low, high, best,lowest, medium am really confused at what could be wrong i have also try it in the initState and also using a *button Here is the full dart code

import 'package:flutter/material.dart';
import 'package:geolocator/geolocator.dart';


class GeoLoc extends StatefulWidget {
  const GeoLoc({Key? key}) : super(key: key);

  @override
  State createState() => _GeoLocState();
}

class _GeoLocState extends State {

  @override
  void initState() {
    super.initState();
    getLoc();
  }

  @override
  Widget build(BuildContext context) {
    return Column(
      children: [
        ElevatedButton(onPressed: () {
          getLoc();
        },
          child: const Text('Get Location'),
        ),
      ],
    );
  }

  getLoc() async{
    bool isLoc  = await Geolocator.isLocationServiceEnabled();
    print(isLoc);
    Position position = await Geolocator.getCurrentPosition(desiredAccuracy: LocationAccuracy.high);
    print(position);
  }
}

Below is your code modified, pls try it. you forget to ask for geolocation permission

import 'package:flutter/material.dart';
import 'package:geolocator/geolocator.dart';


class GeoLoc extends StatefulWidget {
  const GeoLoc({Key? key}) : super(key: key);

  @override
  State createState() => _GeoLocState();
}

class _GeoLocState extends State {

  @override
  void initState() {
    super.initState();
   getLoc()
        .then((value) => print("Location: " + value.toJson().toString()));
  }

  @override
  Widget build(BuildContext context) {
    return Column(
      children: [
        ElevatedButton(onPressed: () {
        getLoc()
        .then((value) => print("Location: " + value.toJson().toString()));
        },
          child: const Text('Get Location'),
        ),
      ],
    );
  }

  getLoc() async{
    bool serviceEnabled;
    LocationPermission permission;

    // Test if location services are enabled.
    serviceEnabled = await Geolocator.isLocationServiceEnabled();
    if (!serviceEnabled) {
      // Location services are not enabled don't continue
      // accessing the position and request users of the
      // App to enable the location services.
      Geolocator.openLocationSettings();
    }

    permission = await Geolocator.checkPermission();
    if (permission == LocationPermission.denied) {
      permission = await Geolocator.requestPermission();
      if (permission == LocationPermission.denied) {
        // Permissions are denied, next time you could try
        // requesting permissions again (this is also where
        // Android's shouldShowRequestPermissionRationale
        // returned true. According to Android guidelines
        // your App should show an explanatory UI now.
        Geolocator.openAppSettings();
      }
    }

    if (permission == LocationPermission.deniedForever) {
      // Permissions are denied forever, handle appropriately.
      return Future.error(
          'Location permissions are permanently denied, we cannot request permissions.');
    }

    // When we reach here, permissions are granted and we can
    // continue accessing the position of the device.
    return await Geolocator.getCurrentPosition();
  }
}

Also make sure you have below permission in your AndroidManifest.xml
