RRulePickerHeaderThemeData? lerp(RRulePickerHeaderThemeData? a, RRulePickerHeaderThemeData? b, double t)

  double t,
) {
  if (identical(a, b)) {
    return a;
  }

  if (a == null && b == null) {
    return null;
  }

  return RRulePickerHeaderThemeData(
    showHeader: t < 0.5 ? a?.showHeader : b?.showHeader,
    style: TextStyle.lerp(a?.style, b?.style, t),
  );
