Implementation

Offset getTotalScrollOffset() {
  double top = scrollTop;
  double left = scrollLeft;
  RenderObject? parentNode = parent;
  while (parentNode != null) {
    if (parentNode is RenderBoxModel) {
      top += parentNode.scrollTop;
      left += parentNode.scrollLeft;
    }
    parentNode = parentNode.parent;
  }
  return Offset(left, top);
