🚀 Internal Changes

✅ _getUserLocationAndSetCountry() Updated

  • Previous Behavior: Showed a Snackbar alert if location permission was denied.
  • New Behavior: Silently falls back to India (IN) without showing a Snackbar.
  • Why? Improves user experience by avoiding unnecessary alerts.

📝 Updated _getUserLocationAndSetCountry()

Future<void> _getUserLocationAndSetCountry() async {
  try {
    Position position = await _determinePosition();
    List<Placemark> placemarks =
        await placemarkFromCoordinates(position.latitude, position.longitude);

    if (placemarks.isNotEmpty) {
      String? countryCode = placemarks.first.isoCountryCode;
      if (countryCode != null) {
        _setCountryFromCode(countryCode);
        return;
      }
    }
  } catch (e) {
    debugPrint("Error getting location: $e");
  }

  // Silent fallback to India (🇮🇳)
  _setCountryFromCode("IN");
}
