reactjs - How to adjust font size to fit view in React Native for Android?

How I can make the font size of the text auto change inside a view in react native?

I have text with different lengths, some of which doesn't fit the view so decreased the font size. I have checked the docs and found this but it's for iOS only and I need it for Android.

And does it work with other components like button and touchableopacity?

A bit improved Jeffy Lee code worked for me

const AdjustLabel = ({
  fontSize, text, style, numberOfLines
}) => {
  const [currentFont, setCurrentFont] = useState(fontSize);

  return (
    <Text
      numberOfLines={ numberOfLines }
      adjustsFontSizeToFit
      style={ [style, { fontSize: currentFont }] }
      onTextLayout={ (e) => {
        const { lines } = e.nativeEvent;
        if (lines.length > numberOfLines) {
          setCurrentFont(currentFont - 1);
        }
      } }
    >
      { text }
    </Text>
  );
};
