adoptChild method
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 childParentData =
child.parentData! as MultiSliverMultiBoxAdaptorParentData;
if (!childParentData._keptAlive) {
childManager.didAdoptChild(child as RenderBox);
}
}
