I am creating an app with Flutter that uses geocoding plugin in order to convert LatLng position to address.
Here my code:
import 'package:geocoding/geocoding.dart';
class HomePage extends StatefulWidget {
const HomePage({Key? key}) : super(key: key);
@override
_HomePageState createState() => _HomePageState();
}
class _HomePageState extends State<HomePage> {
@override
late String location = "location name";
Future<String> getAddress() async {
List<Placemark> placemarks = await placemarkFromCoordinates(
45.478981,9.207120,
localeIdentifier: 'it_It');
return placemarks[0].name.toString();
}
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(title: Text("Convert LatLng to Address")),
body: Center(
child: Stack(children: [
Column(
mainAxisAlignment: MainAxisAlignment.center,
crossAxisAlignment: CrossAxisAlignment.center,
children: [
Text(location),
ElevatedButton(
onPressed: () {
getAddress().then((value) => {
setState(() {
location = value;
}),
print(value)
});
},
child: const Text('Convert LatLng'),
),
],
),
]),
));
}
}
The result of the conversion is different between iOS and Android version, for example:
LatLng = 45.478981,9.207120
iOS version result: "Via Alessandro Tadino 21"
Android version result: "46"
I don't understand why it is different, should I use another plugin? Perhaps the plugin uses two different technologies for iOS and Android. Does Android use a sort of Google Maps plugin?
CodePudding user response:
What you need is reverse geocoding
Reverse geocoding is the process of converting geographic coordinates into a human-readable address.
Since you need exact same outputs on both android and iOS devices, I'd suggest you use Google Geocoding API
Then you can use the API key with google_geocoding package and get places using coordinates
var googleGeocoding = GoogleGeocoding("API-KEY");
var result = await googleGeocoding.geocoding.getReverse(LatLon(40.714224,-73.961452));
