RefNode class

Attaches a Ref to the first web.Element created by child.

In the browser, the mount engine inspects the DOM nodes emitted by child, attaches the first Element instance to ref, and registers Ref.detach into the region's disposer list to clear the ref when unmounted.

In SSR (renderToHtml), child renders normally and ref remains unattached.

final canvasRef = Ref<Object>();

BloomNode chart() => RefNode(
  canvasRef,
  Canvas(attrs: {'id': 'telemetry-canvas'}),
);
