How to get location using Geolocator in Android Studio?

code that has been used.

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

class LoadingScreen extends StatefulWidget {
 @override
  State<StatefulWidget> createState() {
    return _LoadingScreenState();
  }
}

class _LoadingScreenState extends State<LoadingScreen> {
  @override
  void initState() {
   super.initState();
    getLocation();
  }

  void getLocation() async {
    try {
   Position position = await Geolocator.getCurrentPosition(
      desiredAccuracy: LocationAccuracy.low);
    print(position);
   } catch (e) {
    print(e);
    }
  }

  @override
  Widget build(BuildContext context) {
   return Scaffold();
  } 
}

You can use the codes :

var geolocator = Geolocator();
var locationOptions;


getPermission() async {
return Geolocator().checkGeolocationPermissionStatus();
}

then call this function in initState() :

getPermission().then((res) {
  locationOptions =
      LocationOptions(accuracy: LocationAccuracy.high, distanceFilter: 10);
});

 geolocator.getPositionStream(locationOptions).listen((Position position) {
  setState(() {
    lat = position.latitude.toDouble();
    long = position.longitude.toDouble();
  });
});

Your output says "The location service on the device is disabled" so may you should check the permission in the manifest file. I suggest you to use the coarse and fine permissions together.

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>

But you should make a previous verification of the location service too before do geolocation-requests.

you should chechk if the service is enabled:

bool isLocationServiceEnabled  = await Geolocator.isLocationServiceEnabled();
print('location enabled: $isLocationServiceEnabled');

then check if the app has permissions:

LocationPermission permission = await Geolocator.checkPermission();
print(permission);

if you don't have permissions ask for them:

LocationPermission permission = await Geolocator.requestPermission();
print(permission);

with all that set up you can make a secure request

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