onLocationChanged function

Stream<LocationData> onLocationChanged({ bool inBackground = false, })

Listen to the current location.

import 'package:location2/location2.dart';

Future<void> _listenLocation() async {
    _locationSubscription = onLocationChanged(inBackground: _inBackground)
        .handleError((dynamic err) {
      if (err is PlatformException) {

      }
      _locationSubscription?.cancel();

        _locationSubscription = null;
      });
    }).listen((LocationData currentLocation) async {
      setState(() {
        _error = null;
        _location = currentLocation;
      });
      //for Android
      await updateBackgroundNotification(
        onTapBringToFront: true,
        subtitle: 'Location: ${currentLocation.latitude}, '
            '${currentLocation.longitude}',

Implementation

Stream<LocationData> onLocationChanged({bool inBackground = false}) {
  return _platform
      .onLocationChanged(inBackground: inBackground)
      .where((event) => event != null)
      .cast<LocationData>();
}
