Unsafe hook componentWillUpdate

See original GitHub issue

Hi guys I’ve just enabled React.strictMode for my app and the only warning I get is related to Lottie

index.js:1446 Warning: Unsafe lifecycle methods were found within a strict-mode tree:
    in StrictMode

componentWillUpdate: Please update the following components to use componentDidUpdate instead: Lottie

Learn more about this warning here:

That’s the indicted code, is there a safe way to remove the hook without compromising how Lottie work?

Thank you for all 😊 Stefano
