I'm looking for input from people who use typed JavaScript with this library.

1. If you use Flow or TypeScript, how do you type react-native-web exports?
2. If you work across platforms, how do you deal with platform-specific differences in the APIs or components like View?
3. Does this library need to export Flow and TypeScript types?
4. Is there a way to generate TypeScript interfaces from Flow types so you don't need to maintain both?
