Summary: Pull Request resolved: https://github.com/facebook/react-native/pull/50909 Enables and maps the `types_generated/` directory for `react-native` and `react-native/virtualized-lists` — exposing the new Strict TypeScript API entry points to React Native. **New `"exports"` conditions** - `"react-native-strict-api"` — The Strict TypeScript API opt in, exposing the `index.d.ts` entry point only. - `"react-native-strict-api-UNSAFE-ALLOW-SUBPATHS"` — Opts into the new from-source generated types, but allows accessing subpaths (unsafe). - We intend for this unsafe condition to be an escape hatch for Frameworks only (i.e. Expo). Note: In the case of `virtualized-lists`, we simply use the `"types"` condition — since this package did not expose any TypeScript API previously. NOTE: Should we need to roll back JS Stable API phase 1, **this is the single diff to revert**.
