Summary: React Native's TS definitions are currently mostly stored in one monolithic file. This change splits the definitions up to correspond to the source files they came from, and are placed next to the source files. I think this should help inform, and make it easy to update the TS declarations when touching the Flow file. I noticed as part of the change that the typings have not yet removed many APIs that were removed from RN. This is bad, since it means using the removed/non-functional API doesn't cause typechecker errors. Locating typings next to source should prevent that from being able to happen. The organization here means individual TS declarations can declare what will be in the RN entrypoint, which is a little confusing. Seems like a good potential next refactor, beyond the literal translation I did.

React & React Native Versions
This page describes how React and React Native versions interact each other. The version alignment between the two frameworks relies on two syncronization points:
- The versions in the
package.jsonof the new app template. For example for React Native 0.68.1 the versions are aligned as follows:
"dependencies": {
"react": "17.0.2",
"react-native": "0.68.1"
},
- The React renderers shipped with React Native inside this folder, the ./Libraries/Renderer folder, of React Native.
This practically means that you can't bump the version of React in your package.json to a later version,
as you will still be using the older renderer from the folder mentioned above. Bumping the react version in your package.json will lead to unexpected behaviors.
For the sake of React 18, the first version of React Native compatible with React 18 is 0.69.0. Users on React Native 0.68.0 and previous versions won't be able to use React 18.
If you use the react-native upgrade command or the React Native Upgrade Helper, you'll bump to the correct React version once you upgrade React Native.
