unable to select country based on location

[lohithkumar95]

i am using gelocator plugin to get the current location. So, based on that i need to make the initialSelection corresponding to the location countryISO. But when i tried its not updating.

Can i know what could be wrong?
Below is my code to set the initialSelection.

 List<Placemark> p = await geolocator.placemarkFromCoordinates(
          _currentPosition.latitude, _currentPosition.longitude);
      Placemark place = p[0];
      setState(() {
        countryCode = place.isoCountryCode;
      });

InternationalPhoneInput(
             onPhoneNumberChange: _onPhoneNumberChanged,
             initialSelection: countryCode,
             errorText:"Please type a valid phone number",
             errorMaxLines:4,
           ),);
