Add config/property to filter countries

[ritsat]

I can see the function added to filter country based on user input but not able to see the call for this function anywhere. Also not able to see any property to set the country filter criteria. Below existing function code in csc_picker.dart

///filter Country Data according to user input
Future<List<String?>> getCountryData(filter) async {

Please add config/property to set country filter. For example only show certain set of countries just like United State, Canada, etc.

It is now available with this package using countryFilter property.
Hence closing the issue
