Answer 3

I find that, if you want to change both the app name and the package name (i.e. rename the entire app), the following steps are necessary:

• Make sure you don't have anything precious (non-generated, manually copied resources) in the android/ and ios/ subfolders.

• Delete both the android/ and ios/ folder.

• Change the "name" entry in your package.json to the new name.

• Change the app name in both your index.android.js and index.ios.js: AppRegistry.registerComponent('NewAppName', () => App);

• Run react-native upgrade to re-generate the platform subfolders.

• If you have linked resources (like custom fonts etc.) run react-native link.

• If you have other generated resources (like app icons) run the scripts to generate them (e.g. yo).

• Finally, uninstall the old app on each device and run the new one.

You can try this

1. Update displayName in app.json to the new name
2. Delete ios/ and android/ directories
3. Run react-native eject
4. Run react-native link

Answer 6

Try react-native-rename this npm package will ease the process

This package assumes that you created your react-native project 
using react-native init.

Note: This package does not attempt to properly rename build artifacts such as ios/build or Cocoa Pod installation targets. After renaming your project you should clean, build, and reinstall third party dependencies to get it running properly with the new name.

// in project directory

   npx react-native-rename <newName>
