Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/50225
Updates `index.js.flow` to export (what should be) all public types for `react-native`, closely matching the resolved exported types of `types/index.d.ts` (current manual TS defs).
- Note that this first pass doesn't have to be exhaustive (not yet load bearing) — however, I've done a best-effort scan, which passes our current `__typetests__` fixtures.
**Approach: Explicit type imports in `index.js.flow`**
We have a number of options for how we organise and re-export values and types from the new index file — for now, we're opting for explicitly exporting each symbol here.
- While this clutters the index file somewhat, it also provides a single scannable source of truth — without introducing / altering each contributing module's type exports (we might want to do this eventually, but we're far from having strong organisation denoting the public API boundary). It's self-documenting that the index file contains all root exports by name.
- At the same time, we currently have some exceptions that use `export [type] *` to line up with TypeScript `namespace`s. We aim to review and update these within this release cycle, to enforce the above system.

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/48819
Currently, `VirtualizedList-test.js` has a subtle dependency on how asynchronous operations are queued. Specifically, it depends on...
- `Batchinator` to use `setTimeout` for...
- `InteractionManager` to use `setImmediate` for...
- `InteractionManager` to resolve a promise via microtask.
As a consequence, any changes to this queueing logic (e.g. eliminating the unnecessary `setImmediate` and microtask) unnecessarily breaks these unit tests.
This changes the Jest unit tests to instead use `jest. advanceTimersToNextTimer(<step>)` instead of `jest.runOnlyPendingTimers()` so that the unit tests are no longer dependent on these specific queueing logic.

Changelog: [General] [Changed] - fix item disappearing with scroll in VirtualizedList
It was caused because the function `computeWindowedRenderLimits` collapsed the current window size to just 1 element. So, users start scroll current window increase from {left:0, right:5 } -> {left:0, right:6 } and after some edge cases the window collapsed to `{left:6, right:6 }` which cause to remove all elements and recreate them later. As a result users have a lot of lags and blank pages.
The diff fixes the collapsing window size to 1 element. Also fix other decreasing `left` position even if windowSize more than current amount of elements.

Changelog: [General][Fixed] Fixed accuracy of FlatList estimations to determine what elements are visible in the rendering window.
This fixes a bug in FlatList where it thinks that some elements are visible in the rendering window, when they're not. Specifically, if a cell hasn't been laid out yet, it ignores all the information it already has on the ones that had, and estimates its position and offset based on the estimated size of the cells. In this case, if the first element has a larger offset because the list has a header, that offset is ignored in this case.
One observed result of this is that in a list where there's a header and a single cell that occupy the whole rendering window, FlatList thinks it needs to pre-render an additional element because the header is ignored.

Reducing the boundary of rerender of virtual lists. Previously with prop: "strictMode={true}" the VirtualizedList still re rendered each CellRenderer component. Because method getDerivedStateFromProps generated every time a new uniq state and the cells didn’t have a PureComponent. It helps to improve react performance for lists which have 5+ elements.
