insertRenderObjectChild method

@override void insertRenderObjectChild(covariant RenderObject child, covariant dynamic slot)

Insert the given child into renderObject at the given slot.

The semantics of slot are determined by this element. For example, if this element has a single child, the slot should always be null. If this element has a list of children, the previous sibling element wrapped in an IndexedSlot is a convenient value for the slot.

Implementation

@override
void insertRenderObjectChild(
    covariant RenderObject child, covariant dynamic slot) {
  assert(renderObject.debugValidateChild(child));

  assert(child is RenderBox);
  if (slot == _minExtentPrototypeSlot) {
    renderObject.minProtoType = child as RenderBox;
  } else if (slot == _maxExtentPrototypeSlot) {
    renderObject.maxProtoType = child as RenderBox;
  } else {
    renderObject.child = child as RenderBox;
  }
}
