npx expo install lottie-react-native

in your project. Then, follow the additional instructions as mentioned by library's README under "Installation in bare React Native projects" section.
¥Usage
import { useRef, useEffect } from 'react';
import { Button, StyleSheet, View } from 'react-native';
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={{
width: 200,
