One is a React framework for web, iOS, and Android apps.

// web counterpart of routeHmr.native.ts. Web route Fast Refresh happens through
// the `one-hmr-update` event (see useScreens' web block), so this is a no-op store
// whose exports let useScreens import `./routeHmr` on either platform.

  return () => {}
