Writing a Native Module for React Native Using Kotlin

A step-by-step guide to building a native UI component for React Native using Kotlin on Android. The tutorial covers setting up Kotlin dependencies in build.gradle, creating a ReactPackage class, implementing a SimpleViewManager to render a YouTubePlayerView using the android-youtube-player library, and exposing a videoId prop via @ReactProp so videos can be loaded from JavaScript. The result is a reusable react-native-utube-player component that can be imported and used in any React Native app.
