@override
Widget buildCustom({
  ChildWidgetBuilder? childBuilder,
  required BuildContext context,
  required JsonWidgetData data,
  Key? key,
}) {
  assert(
    data.children?.length == 1 || data.children?.isNotEmpty != true,
    '[JsonTweenAnimationBuilder] only supports zero or one child.',
  );

  return _JsonTweenAnimation(
    builder: this,
    childBuilder: childBuilder,
    data: data,
    key: key,
