Please select affected platform(s)

• [X] Android
• [X] iOS

Steps to reproduce

1. call placemarkFromCoordinates() with latitude 37.09024 & longitude -95.712891
2. it's a coordinate for USA location, but it's giving isoCountryCode as "IN" when i'm trying to fetch details from India

Note: It's happening only when i'm working with it on india location, if i'm doing from USA location then it's working fine

Expected results

it should provide country code as "US" for any USA location

Actual results

it's giving "IN" for any USA location if i'm calling the function on an application running in India

Code sample

Code sample

  getLocationDetails(BuildContext context, String placeId) async {
    debugPrint(placeId);
    final gPlace.DetailsResponse? details =
        await googlePlace.details.get(placeId, language: "en");
    predictions = [];
    List<Placemark> placemarks = await placemarkFromCoordinates(
        _startPosition!.geometry!.location!.lat!,
        _startPosition!.geometry!.location!.lng!,
        localeIdentifier: "en");
    _userCountry = placemarks[0].country;
    _locality = placemarks[0].street;
    _postalCode = placemarks[0].postalCode;
    _latitude = "${_startPosition!.geometry!.location!.lat}";
    _longitude = "${_startPosition!.geometry!.location!.lng}";
    _userCoutryCode = placemarks[0].isoCountryCode;
    debugPrint(
        "Show country code: ${placemarks[0].isoCountryCode} ${details.result!.addressComponents![0].shortName}");
    _userState = placemarks[0].administrativeArea;
    _userCity = placemarks[0].locality! == ""
        ? placemarks[0].subLocality! == ""
            ? placemarks[0].name
            : placemarks[0].subLocality!
        : placemarks[0].locality!;
    FocusScope.of(context).requestFocus(FocusNode());
    notifyListeners();
  }
