addToScene method

  1. @override
EngineLayer addToScene (SceneBuilder builder, [ Offset layerOffset = Offset.zero ])
override

Override this method to upload this layer to the engine.

Return the engine layer for retained rendering. When there's no corresponding engine layer, null is returned.

Implementation

@override
ui.EngineLayer addToScene(ui.SceneBuilder builder, [ Offset layerOffset = Offset.zero ]) {
  builder.pushBackdropFilter(filter);
  addChildrenToScene(builder, layerOffset);
  builder.pop();
  return null; // this does not return an engine layer yet.
}
