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) {
  super.insertRenderObjectChild(child, slot);
  if (child is RenderRulers) {
    renderObject.addRuler(child);
  } else if (child is RenderRulerLabel) {
    renderObject.addRulerLabel(child);
  } else if (child is RenderLinearGaugeWidgetPointer) {
    renderObject.addWidgetPointer(child);
  } else if (child is RenderLinearGaugeShapePointer) {
    renderObject.addShapePointer(child);
  } else if (child is RenderValueBar) {
    renderObject.addValueBar(child);
  } else if (child is RenderCurve) {
    renderObject.addCurve(child);
  }
}
