Build native UI components in React Native

The article explores the concept of native UI components in React Native, a JavaScript framework for building natively rendered mobile applications, and provides a comprehensive guide on creating these components for both Android and iOS platforms. It highlights how developers can convert existing native Java or Objective-C components into React Native components, enabling the reuse of native code logic. The piece details the process of setting up a React Native project, creating a CameraView component to render a live camera feed, and implementing native UI components using Java for Android and Objective-C for iOS. It emphasizes the importance of understanding how to manage native modules and handle commands from JavaScript to enhance app functionality. The article concludes by noting the utility of native UI components for implementing features not inherently supported by React Native and for transitioning existing apps to this framework.
