How to get current user Geolocation in Flutter

In this Google Flutter code snippet example, we are going to learn How to get current location in flutter geolocation.

You can copy and adopt this source code example to your flutter project easily without issues.

Add this code to your pubspec.yaml file

geolocator: ^5.0.0
permission_handler: ^3.0.1
google_maps_flutter: ^0.5.19

Create a get_current_location.dart file (use any name of your choice) and add this code:

 import 'dart:async';

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

class GetCurrentLocation extends StatefulWidget {
  @override
  _GetCurrentLocationState createState() => _GetCurrentLocationState();
}

class _GetCurrentLocationState extends State<GetCurrentLocation> {
  Completer<GoogleMapController> _controller = Completer();
  static LatLng latLng;

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

   Future<void> getLocation() async {
    PermissionStatus permission = await PermissionHandler()
        .checkPermissionStatus(PermissionGroup.location);
    if (permission == PermissionStatus.denied) {
      await PermissionHandler()
          .requestPermissions([PermissionGroup.locationAlways]);
    }

    var geolocator = Geolocator();
    GeolocationStatus geolocationStatus =
        await geolocator.checkGeolocationPermissionStatus();
    switch (geolocationStatus) {
      case GeolocationStatus.denied:
        print('denied');
        break;
      case GeolocationStatus.disabled:
      case GeolocationStatus.restricted:
        print('restricted');
        break;
      case GeolocationStatus.unknown:
        print('unknown');
        break;
      case GeolocationStatus.granted:
        await Geolocator()
            .getCurrentPosition(desiredAccuracy: LocationAccuracy.high)
            .then((Position _position) {
          if (_position != null) {
            setState((){
            latLng = LatLng(_position.latitude, _position.longitude,);
            });
          }
        });
        break;
    }
  }


  void _onMapCreated(GoogleMapController controller) {
    _controller.complete(controller);
  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('Get Current Location on Google Maps'),
          backgroundColor: Colors.red,
        ),
        body: GoogleMap(
          onMapCreated: _onMapCreated,
          initialCameraPosition: CameraPosition(
            target: latLng,
            zoom: 11.0,
          ),
        ),
      ),
    );
  }
}

In your main.dart file (main entry point of the app), add this:

import 'package:inducesmile/get_current_location.dart';

void main() => runApp(new MyApp());

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return new MaterialApp(
      debugShowCheckedModeBanner: false,
      title: 'Flutter Code Snippets',
      theme: new ThemeData(primarySwatch: Colors.red),
      home: new GetCurrentLocation(),
    );
  }
}
