onUnmount method

@override void onUnmount()

Called when the owning node leaves a live scene graph.

Implementation

@override
void onUnmount() {
  // Guard on attachment, not mount state (mirrors MeshComponent): the
  // render scene is still reachable during teardown after the mounted flag
  // is cleared.
  if (isAttached) {
    node.internalRenderScene?.removeSpotLight(this);
  }
}
