insertRenderObjectChild method

@override void insertRenderObjectChild(covariant RenderObject child, covariant IndexedSlot<Element?>? 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(
    RenderObject child, IndexedSlot<Element?>? slot) {
  final renderObject = this.renderObject;
  assert(renderObject.debugValidateChild(child));
  renderObject.insert(child, after: slot?.value?.renderObject);
  assert(renderObject == this.renderObject);
}
