How to disable font scaling in React Native for IOS app?

Question

Enlargement of size of the device font will sometimes break (Styling wise).

Answer 1

 if (Text.defaultProps == null) {
            Text.defaultProps = {};
            Text.defaultProps.allowFontScaling = false;
        }

I kept this piece of code inside the constructor of index.js.It really worked well. By the I am using react native version 0.59.9 FYI.
