Summary:
I wanted to configure the RN dev menu without having to write native code. This is pretty useful in a greenfield app since it avoids having to write a custom native module for both platforms (and might enable the feature for expo too).
This ended up a bit more involved than planned since callbacks can only be called once. I needed to convert the `DevSettings` module to a `NativeEventEmitter` and use events when buttons are clicked. This means creating a JS wrapper for it. Currently it does not export all methods, they can be added in follow ups as needed.
## Changelog
[General] [Added] - Export the DevSettings module, add `addMenuItem` method
Pull Request resolved: https://github.com/facebook/react-native/pull/25848
Test Plan:
Tested in an app using the following code.
```js
if (__DEV__) {
DevSettings.addMenuItem('Show Dev Screen', () => {
dispatchNavigationAction(
NavigationActions.navigate({
routeName: 'dev',
}),
);
});
}
```
Added an example in RN tester

Summary:
It doesn't work super smoothly, but I don't think we should hide it. The ultimate goal is to get it working well in Fabric.

Summary:
Android implementation of the Appearance native module. Exposes the user's preferred color scheme: "dark" for Night theme ON, "light" for Night theme OFF.
Emits a `appearanceChanged` event when the current uiMode configuration changes.
To make your app handle Night mode changes, make sure to do the following:
* Declare your Activity can handle uiMode configuration changes (https://developer.android.com/preview/features/darktheme#java):
```
android:configChanges="uiMode"
```
* Make sure to pass the configuration changed activity lifecycle callback from your ReactActivity:
```
Override
protected void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged();
if (mReactInstanceManager != null) {
mReactInstanceManager.onConfigurationChanged(newConfig);
}
}
```

This module is being removed from React Native via Lean Core. This diff moves all the related JS files to FB internal.
Note: I removed two references to previously removed modules from some files in this diff. I hope you don't mind.

Summary:
Add example showing regression before this fix is applied.
https://github.com/facebook/react-native/pull/18187 Was found to introduce a regression in some internal facebook code-base end to end test which couldn't be shared. I was able to create a reproducible demo of a regression I found, and made a fix for it. Hopefully this will fix the internal test, such that the pr can stay merged.
