Custom builder that subclasses must override and implement to return the actual Widget to be placed on the tree.

Implementation

@override
Widget buildCustom({
  ChildWidgetBuilder? childBuilder,
  required BuildContext context,
  required JsonWidgetData data,
  Key? key,
}) {
  assert(
    data.children?.length == 1 || data.children?.isNotEmpty != true,
    '[JsonSetDefaultValueBuilder] only supports zero or one child.',
  );
  values?.forEach((key, value) {
    if (data.registry.getValue(key) == null) {
      data.registry.setValue(
        key,
        value,
        originator: null,
      );
    }
  });

  var child = data.children?.isNotEmpty == true ? data.children![0] : null;
  child = child?.recreate();

  return child?.build(
        childBuilder: childBuilder,
        context: context,
      ) ??
      SizedBox(key: key);
}
