adoptChild method

  1. @override
void adoptChild (covariant RenderObject child)
override

Called by subclasses when they decide a render object is a child.

Only for use by subclasses when changing their child lists. Calling this in other cases will lead to an inconsistent tree and probably cause crashes.

Implementation

@override
void adoptChild(RenderObject child) {
  assert(_debugCanPerformMutations);
  assert(child != null);
  setupParentData(child);
  markNeedsLayout();
  markNeedsCompositingBitsUpdate();
  markNeedsSemanticsUpdate();
  super.adoptChild(child);
}
