insertRenderObjectChild method
- covariant RenderObject child,
- covariant int slot
override
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, int slot) {
final RenderListWheelViewport renderObject = this.renderObject;
assert(renderObject.debugValidateChild(child));
renderObject.insert(child as RenderBox, after: _childElements[slot - 1]?.renderObject as RenderBox?);
assert(renderObject == this.renderObject);
}
