Update SectionList to accept React elements for separators ( #53599 )
...
Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/53599
Runtime and types fix for the `ItemSeparatorComponent` prop on `virtualized-list` components (`FlatList`, `SectionList`, `VirtualizedList`).
- Docs source, where this prop (adjacent to other `*Component` props) is documented as accepting elements: https://reactnative.dev/docs/virtualizedlist#itemseparatorcomponent .
- Existing runtime behaviour matching this definition: https://github.com/facebook/react-native/blob/8d33e1c205b12fe27f4319e6566bb0c088197810/packages/virtualized-lists/Lists/VirtualizedListCellRenderer.js#L197-L203
**Changes**
- Update Flow, manual TS type defs.
- Align runtime behaviour in `VirtualizedSectionList` to add matching `React.isValidElement()` behaviour.
Resolves https://github.com/facebook/react-native/issues/53531 .
Changelog:
[General][Fixed] - The `ItemSeparatorComponent` prop on list components now accepts a React element as well as a component function.

...
Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/51383
This diff is a set of alignments/improvements in generated TS types. It includes:
- extending `AppStateStatus` with `extension` and `unknown`,
- exporting `AnimatedProps` under `Animated` namespace,
- resolving issue with discriminated unions in `ProgressBarAndroidTypes`,
- fixing `StyleSheet.create` type to accept only specified style properties,
- extending `TextProps` with `AccessibilityProps`,
extending Fn Args generic with `$ReadOnlyArray` in `ErrorUtils`,
- small `__typetests__` adjustments,
- removing type test `styleDimensionValueValidAnimated` as `DimensionValue` no longer accepts `AnimatedNode`,
- removing `styleDimensionValueInvalid` as `DimensionValue` accepts any string now - template literal types in Flow are not supported,
- changing `overlayColor` type to `ColorValue` to align with manual types,
- fixing `AnimatedPropsAllowList` type which wasn't correct in TS because index signature type was different from style type,
- using `DeviceEventEmitter` instead of `DeviceEventEmitterStatic` in type tests which is equivalent in both new and old types - `DeviceEventEmitterStatic` was only a type of `DeviceEventEmitter`,
- removing type test for checking forwarded key type - doesn't work with new types and that shouldn't be supported,
- removing `Animated.legacyRef` type test - not included in new types,
- adding `DOMRect` from "dom" lib to `globals.d.ts` to not include "dom" lib in the tsconfig - tries to compare globals with `lib.dom.d.ts` and produces many errors,
- exporting `SectionListData`,

- fixes component unmounting behaviour in itemSeperatorComponent ( #43223 )
...
Summary:
Reopen in reference to https://github.com/facebook/react-native/issues/42435 , as it had a lot of commits and fixes making it messed up.
Weirdly when using a [Section List](https://reactnative.dev/docs/sectionlist ) specifically when using the [SectionSeperatorComponent](https://reactnative.dev/docs/sectionlist#sectionseparatorcomponent ), and adding additional Data on the renderItem List, there is a unmount occurring as the new Data is added, this only happens while using the `SectionSeparatorComponent` and limited to the same
**Here is the Current Behaviour**
https://github.com/facebook/react-native/assets/72331432/0622e789-ddbc-4038-8ccc-a421050eecbf
**Here is the Expected Behaviour After Fixes**
https://github.com/facebook/react-native/assets/72331432/2f0cc3a9-da97-43f5-8a4b-3faca74ae834
The issues is happening because the Parent View gets removed, as we add Data, the separator moves causing the unmount, the solution that i proposed here is to conditionally render to make sure that our separator renders correctly which required to add an empty view as the `itemSeparatorComponent`.
## Changelog:
[General] [Added] - Fixes SectionList Unmounting issue with separatorComponent on data addition and removal.

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/37777
This extracts the state and logic VirtualizedList uses to query information related to cell metrics. We will need to modify this (and other places) when fixing up RTL support for horizontal FlatList.

Rename FrameMetrics to CellMetrics ( #37778 )

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/37778
These functions describe how to get the metrics of a specific cell. "Frame" here seems non-descriptive and redundant to the "Metrics" part. Renaming this before a larger refactor.

Pull Request resolved: https://github.com/facebook/react-native/pull/36960
We're deprecating the unsafe `$Shape` and moving to the safe `Partial`: https://fb.workplace.com/groups/flowlang/posts/1251655088773485
I have previously codemodded all locations that do not cause errors. Now start on the remaining ones: codemod and suppress.

It is expected this diff will individually fail. The entire stack should be applied at once.
