get exact latitude longitude flutter code example

Example 1: flutter geolocator web

@JS('navigator.geolocation') // navigator.geolocation namespace
 library jslocation; // library name can be whatever you want

 import "package:js/js.dart";

@JS('getCurrentPosition') // Accessing method getCurrentPosition 
from       Geolocation API
external void getCurrentPosition(Function success(GeolocationPosition pos));

@JS()
@anonymous
class GeolocationCoordinates {
  external double get latitude;
  external double get longitude;
  external double get altitude;
  external double get accuracy;
  external double get altitudeAccuracy;
  external double get heading;
  external double get speed;

external factory GeolocationCoordinates(
  {double latitude,
  double longitude,
  double altitude,
  double accuracy,
  double altitudeAccuracy,
  double heading,
  double speed});
  }

@JS()
@anonymous
class GeolocationPosition {
external GeolocationCoordinates get coords;

external factory GeolocationPosition({GeolocationCoordinates 
coords});
}

Example 2: get location name in flutter

import 'package:geocoder/geocoder.dart';

// From a query
final query = "1600 Amphiteatre Parkway, Mountain View";
var addresses = await Geocoder.local.findAddressesFromQuery(query);
var first = addresses.first;
print("${first.featureName} : ${first.coordinates}");

// From coordinates
final coordinates = new Coordinates(1.10, 45.50);
addresses = await Geocoder.local.findAddressesFromCoordinates(coordinates);
first = addresses.first;
print("${first.featureName} : ${first.addressLine}");
