didAdoptChild method

  1. @override
void didAdoptChild (RenderBox child)
override

Called during RenderSliverMultiBoxAdaptor.adoptChild.

Subclasses must ensure that the SliverMultiBoxAdaptorParentData.index field of the child's RenderObject.parentData accurately reflects the child's index in the child list after this function returns.

Implementation

@override
void didAdoptChild(RenderBox child) {
  assert(_currentlyUpdatingChildIndex != null);
  final SliverMultiBoxAdaptorParentData childParentData = child.parentData;
  childParentData.index = _currentlyUpdatingChildIndex;
}
