1-) FLUTTER - bulunduğum konumu alma geolocator get user location map kullanımı

compileSdkVersion 33

minSdkVersion 21
targetSdkVersion 33

1. ADIM -> terminale yaz -> flutter pub add geolocator

2. ADIM (AndroidManifest.xml)

 <uses-permission android:name=
     "android.permission.ACCESS_COARSE_LOCATION"/>
 <uses-permission android:name=
     "android.permission.ACCESS_FINE_LOCATION"/>

<application

2.1 ADIM (ios/Runner/Info.plist)

<key>NSLocationWhenInUseUsageDescription</key>
<string>This app needs access to location when open.</string>

3. ADIM (determinePosition metodu)

Future<Position> _determinePosition() async {
  bool serviceEnabled;
  LocationPermission permission;

  // Test if location services are enabled.
  serviceEnabled = await Geolocator.isLocationServiceEnabled();
  if (!serviceEnabled) {
    // Location services are not enabled don't continue
    // accessing the position and request users of the
    // App to enable the location services.
    return Future.error('Location services are disabled.');
  }

  permission = await Geolocator.checkPermission();
  if (permission == LocationPermission.denied) {
    permission = await Geolocator.requestPermission();
    if (permission == LocationPermission.denied) {
      // Permissions are denied, next time you could try
      // requesting permissions again (this is also where
      // Android's shouldShowRequestPermissionRationale
      // returned true. According to Android guidelines
      // your App should show an explanatory UI now.
      return Future.error('Location permissions are denied');
    }
  }

  if (permission == LocationPermission.deniedForever) {
    // Permissions are denied forever, handle appropriately.
    return Future.error(
        'Location permissions are permanently denied, we cannot request permissions.');
  }

  // When we reach here, permissions are granted and we can
  // continue accessing the position of the device.
  return await Geolocator.getCurrentPosition();
}

4. ADIM KULLANIMI

@override
void initState() {
  super.initState();
    var postion = _determinePosition().then((value) {
    String latitude = value.latitude.toString();
    String longitude = value.longitude.toString();
    EasyLoading.showToast(latitude+" "+longitude);
  });

}

5. ADIM şehir/il ve ilçe alma

terminal çalıştır -> flutter pub add geocoding

açıklama : determinePosition metodu yukarıdan kopyalıcaz

void getLocation() {
  try {

  _determinePosition().then((position) async {

      List<Placemark> placemarks = await placemarkFromCoordinates(
        position.latitude,
        position.longitude,
      );

      //EasyLoading.showToast(placemarks[0].toString());
      

String il = placemarks.first.administrativeArea ?? ""; // null ise "" yap değilse kendini al

String ilce = placemarks.first.subAdministrativeArea ?? "";

EasyLoading.showToast(il+"-"+ilce);

  });

  } catch (err) {}

}

@override
void initState() {
  super.initState();
  getLocation();

}

6. ADIM WEB İÇİN BU KODLARI KULLANMAN LAZIM

kaynak : https://pub.dev/packages/osm_nominatim/example

flutter pub add osm_nominatim

açıklama : webde ilçe de yanılma payı olabilir. lat ve log den sorgulayıp buluyoruz.

import 'package:flutter/foundation.dart' show kIsWeb;

void getLocation() {
  try {
    _determinePosition().then((position) async {
      if (kIsWeb) {
        final reverseSearchResult = Nominatim.reverseSearch(
          lat: position.latitude,
          lon: position.longitude,
          addressDetails: true,
          extraTags: true,
          nameDetails: true,
        ).then((adres) {

          adres.address!.forEach((key, value) {
            switch(key){
              case "province":
                StatikSinif.il = value;
                break;
              case "town":
                StatikSinif.ilce = value;
                break;
            }
            print(key.toString()+"-"+value.toString());
          });

          EasyLoading.showToast(StatikSinif.il + "-" + StatikSinif.ilce);

        });
      } else {
        List<Placemark> placemarks = await placemarkFromCoordinates(
          position.latitude,
          position.longitude,
        );

        String il = placemarks.first.administrativeArea ??
            ""; // null ise "" yap değilse kendini al
        String ilce = placemarks.first.subAdministrativeArea ?? "";
        StatikSinif.il = il;
        StatikSinif.ilce = ilce;

        EasyLoading.showToast(il + "-" + ilce);
      }
    });
  } catch (err) {}
