import LottieView from 'lottie-react-native';

export default function App() {
const animation = useRef<LottieView>(null);
useEffect(() => {
  // You can control the ref programmatically, rather than using autoPlay
  // animation.current?.play();
}, []);

return (
  <View style={styles.animationContainer}>
    <LottieView
      autoPlay
      ref={animation}
      style={{
