getting location in flutter using geolocator

Comment

import 'package:geolocator/geolocator.dart';

/// Determine the current position of the device.
///
/// When the location services are not enabled or permissions
/// are denied the `Future` will return an error.

  // Test if location services are enabled.
  serviceEnabled = await Geolocator.isLocationServiceEnabled();
  if (!serviceEnabled) {

    // accessing the position and request users of the 
    // App to enable the location services.

  if (permission == LocationPermission.denied) {
    permission = await Geolocator.requestPermission();

      // requesting permissions again (this is also where
      // Android's shouldShowRequestPermissionRationale 
      // returned true. According to Android guidelines
      // your App should show an explanatory UI now.
      return Future.error('Location permissions are denied');
    }
  }
  
  if (permission == LocationPermission.deniedForever) {

      '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.

should I use geolocator or location in flutter

Comment

Both seem to have the same functionality.

But I would stick to geolocator because:

more actively developed

uses FusedLocationProviderClient, and LocationManager if not available

is supported by a company instead of a single maintainer

I hope it helps
