Override this method in subclasses with child nodes to call redepthChild for each child. Do not call this method directly.

Implementation

@override
void redepthChildren() {
  ChildType? child = _firstChild;
  while (child != null) {
    redepthChild(child);
    final ParentDataType childParentData = child.parentData! as ParentDataType;
    child = childParentData.nextSibling;
  }
}
