Summary: When you write platform-specific code using [file extensions](https://facebook.github.io/react-native/docs/platform-specific-code#platform-specific-extensions), you can specify `.ios.js`, `.android.js`, or the catch-all `.native.js` when you are sharing code with a web project. This `native` shortcut is missing for the `Platform.select` method, and this PR is adding support for that. ## Changelog [General] [Added] - Platform.select now supports native as an option. Pull Request resolved: https://github.com/facebook/react-native/pull/26966 Test Plan: Added relevant passing unit tests for Platform module.
