Flutter - <asynchronous suspension> with geocoder package - flutter

Question

I need to get the city name from Longitude and Latitude.
I do not found a single package to do that, so I use location package to get Long and Lat and used geocoder to get the city name.
But I keep have this error and have no result :
[ERROR:flutter/lib/ui/ui_dart_state.cc(177)] Unhandled Exception: PlatformException(failed, Failed, null, null)
and this one after it on the console: < asynchronous suspension >
Here is my code :
class _ProfileScreenState extends State<ExploreScreen> {
dynamic currentLocation;
double userLongitude;
double userLatitude;
Coordinates coordinates;
var addresses;
var first;
#override
initState() {
super.initState();
_getCurrentLongAndLat();
_getCurrentPosition(userLatitude, userLatitude);
}
Future _getCurrentLongAndLat() async {
currentLocation = LocationData;
var error;
var location = new Location();
try {
currentLocation = await location.getLocation();
userLatitude = currentLocation.latitude;
userLongitude = currentLocation.longitude;
print('$userLatitude $userLatitude');
} on PlatformException catch (e) {
if (e.code == 'PERMISSION_DENIED') {
error = 'Permission denied';
}
currentLocation = null;
}
}
Future _getCurrentPosition(double long, double lat) async {
coordinates = new Coordinates(userLatitude, userLongitude);
addresses = await Geocoder.local.findAddressesFromCoordinates(coordinates);
print(addresses.first);
}
}

Answer 1

I realized flutter packages geolocator and location conflict with each other sometimes.
Try using geolocator to get your current position:
Future _getCurrentPosition() async {
Geolocator.getCurrentPosition(desiredAccuracy: LocationAccuracy.high).then((Position position) {
setState(() {
_currentPosition = position;
userLongitude = position.longitude;
userLatitude = position.latitude;
});
});
}
It is a Future, so you can use await to really wait for results and after that call the getAddress function with the userLat and userLng.
