Steps to reproduce

Description

The geocode package is returning incorrect administrative area information for coordinates in Istanbul, Turkey. The coordinates point to Esenyurt district (Atatürk Mahallesi), but the package returns Büyükçekmece district instead.

Expected results

• Coordinates: 41.030011, 28.6397551
• Expected Location: Atatürk Mahallesi, Esenyurt, Istanbul
• Verification: Google Maps correctly identifies this location as Esenyurt

Actual results

• Returned Location: Atatürk, Büyükçekmece, Istanbul
• Issue: The district (ilçe) is incorrectly identified as Büyükçekmece instead of Esenyurt

Code sample

Code sample

Future getDetailedAddress(double lat, double lng) async {
  // Test coordinates in Esenyurt, Istanbul
  lat = 41.030011;
  lng = 28.6397551;

  try {
    List placemarks = await placemarkFromCoordinates(lat, lng);

    if (placemarks.isNotEmpty) {
      Placemark place = placemarks.first;

      // Debug output
      print('subLocality: ${place.subLocality}');
      print('thoroughfare: ${place.thoroughfare}');
      print('subThoroughfare: ${place.subThoroughfare}');
      print('subAdministrativeArea: ${place.subAdministrativeArea}');
      print('administrativeArea: ${place.administrativeArea}');
      print('locality: ${place.locality}');
      print('country: ${place.country}');

      List addressParts = [];

      if (place.subLocality != null && place.subLocality!.isNotEmpty) {
        addressParts.add(place.subLocality!);
      }

      if (place.thoroughfare != null && place.thoroughfare!.isNotEmpty) {
        addressParts.add(place.thoroughfare!);
      }

      if (place.subThoroughfare != null && place.subThoroughfare!.isNotEmpty) {
        addressParts.add('No: ${place.subThoroughfare}');
      }

      if (place.subAdministrativeArea != null && place.subAdministrativeArea!.isNotEmpty) {
        addressParts.add(place.subAdministrativeArea!);
      }

      if (place.administrativeArea != null && place.administrativeArea!.isNotEmpty) {
        addressParts.add(place.administrativeArea!);
      }

      return addressParts.join(', ');
    }

    return null;
  } catch (e) {
    print('Error: $e');
    return null;
  }
