buildWidget method
The widget for the moment the fx plane is parked at.
A compiled node builds through its own generated class, which reaches the declaration itself — which is why a shipped app hands the view nothing. A read one goes through whatever bound it.
Implementation
Object? buildWidget() => switch (declared) {
var d? => d.merge(SceneArgs(renderedArgs)).build(),
null => builder?.call(SceneArgs(renderedArgs)),
};
