Implementation 

void scheduleInitialLayout() {
  assert(attached);
  assert(parent is! RenderObject);
  assert(!owner._debugDoingLayout);
  assert(_relayoutBoundary == null);
  _relayoutBoundary = this;
  assert(() {
    _debugCanParentUseSize = false;
    return true;
  }());
  owner._nodesNeedingLayout.add(this);
}
