          (Set<WidgetState> states) {
        if (states.contains(WidgetState.hovered)) {
          return RoundedRectangleBorder(
            borderRadius: BorderRadius.circular(20),
          );
        }
        return RoundedRectangleBorder(
          borderRadius: BorderRadius.circular(5),
        );
      }),
    )
