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.
