adoptChild method

@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) {
  super.adoptChild(child);
  final SliverMultiBoxAdaptorParentData childParentData = child.parentData;
  if (!childParentData._keptAlive)
    childManager.didAdoptChild(child);
}
