my code is very simple,

// init background geolocation void initGeolocation() async { debugPrint('geo'); _geoSubscription = Geolocation.locationUpdates( accuracy: LocationAccuracy.best, displacementFilter: 10.0, // in meters inBackground: true, // by default, location updates will pause when app is inactive (in background). Set to true to continue updates in background. ).listen((result) { debugPrint('result'); debugPrint(result.dataToString()); if (result.isSuccessful) { // todo with result _latitude = result.location.latitude; _longitude = result.location.longitude; debugPrint(result.dataToString()); } }); }

Sorry for the delay. It should be fixed in the latest release 1.0.0.
