I think I'd prefer to use PreviewProvider instead, but as you want.

Yes, that's probably better but it would require to change much more classes. Also those classes do not provide Preview but States, so naming them ...StateProvider make also some sense... Or the suffix could be PreviewParameterProvider but this is getting long!
