Getting Started

Update MainActivity.kt to extends FlutterFragmentActivity vs FlutterActivity. Otherwise you'll get an error.

//import io.flutter.embedding.android.FlutterActivity
import io.flutter.embedding.android.FlutterFragmentActivity

class MainActivity: FlutterFragmentActivity() {
}

IOS Configuration

Add the following to your info.plist file

    <dict>
        ...
        <key>NSLocationWhenInUseUsageDescription</key>
        <string>Do you allow this app to know your current location?</string>
        <true/>
        ...
    </dict>

Android Configuration

Add the following permissions to the app level Android Manifest

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

How to use ?

The plugin have to mathods requestLocationPermission and getCurrentLocation

Call requestLocationPermission to request location permission, it will show the location permission popup and return true or false. Call getCurrentLocation to get the current location, it will return an object TldrLatLng with latitude and longitude.

• Initialize the plugin

  final locationPlugin = TldrGetLocation();

• Ask for location permission

  final bool permissionGranted =
    await locationPlugin.requestLocationPermission();

• Get current location

  TldrLatLng? location = await locationPlugin.getCurrentLocation();
  // check if null before using
  double? latitude = location?.latitude;
  double? longitude = location?.longitude;

import 'package:flutter/material.dart';
import 'package:tldr_get_location/model.dart';
import 'package:tldr_get_location/tldr_get_location.dart';

void main() {
  runApp(const MyApp());

        ),
        body: const LocationWidget(),
      ),
    );
  }
}

class LocationWidget extends StatefulWidget {
  const LocationWidget({super.key});

  @override

            child: const Text('Get Location'),
          ),
        ],
      ),
    );
