A library that allows rendering After Effects animations.
This library is listed in the Expo SDK reference because it is included in Expo Go. You may use any library of your choice with development builds.
Lottie renders After Effects animations in real time, allowing apps to use animations as easily as they use static images.
- npx expo install lottie-react-nativeIf you are installing this in an existing React Native app, start by installing expo in your project. Then, follow the additional instructions provided by the library's README or documentation.

// You can control the ref programmatically, rather than using autoPlay
// animation.current?.play();
}, []);
