Add state node on Offscreen fibers with id (in preparation for transition tracing)

acdlite · 2022-03-03T19:42:36Z

 import type {ReactNodeList, OffscreenMode} from 'shared/ReactTypes';
 import type {Lanes} from './ReactFiberLane.old';
 import type {SpawnedCachePool} from './ReactFiberCacheComponent.new';
+import {number} from 'prop-types';


Don't need this. Maybe this was an auto-import?

 |};
+
+export type OffscreenInstance = {|
+  id: number,


Can you leave this as an empty object for now? Not convinced yet we need to have a numeric id, since we can use the object itself as a key. But even if we do, we can figure that out in the next PR.

    fallbackChildFragment.flags |= Placement;
  }

+  primaryChildFragment.stateNode = current.stateNode;


You don't need to copy this. It's copied during createWorkInProgress.

    );
  }

+  primaryChildFragment.stateNode = primaryChildInstance;


I think you also need to do this in updateOffscreenComponent, because once <Offscreen /> is a public API, it won't have been rendered by a Suspense parent that initializes the instance here.

But it might be best to do it in createOffscreenFiber:

https://github.com/facebook/react/blob/cb1e7b1c6ccd989d54b376ee4ae9da72a34f96e5/packages/react-reconciler/src/ReactFiber.new.js#L721-L731

That's where HostPortal initializes its instance
