debugMountInto method

  1. @visibleForTesting
void debugMountInto(
  1. RenderScene renderScene
)

Mounts this subtree into renderScene without a full Scene.

Scene construction touches the GPU context, which is unavailable in unit tests, so this seam lets render-lifecycle tests exercise the mount / unmount path (and the RenderItem registration it drives) against a bare RenderScene.

Implementation

@visibleForTesting
void debugMountInto(RenderScene renderScene) => _mount(renderScene);
