The useLayoutEffect hook is similar to useEffect, but it is invoked synchronously after all DOM mutations. It is used for layout effects and can be useful for measuring DOM elements.
Solution Code
React Native
-- Example Code --
import React, { useLayoutEffect, useRef } from "react";
import { View, Text } from "react-native";
const App = () => {
const ref = useRef(null);
useLayoutEffect(() => {
if (ref.current) {
console.log(ref.current.measure());
}
}, []);
return (
<View ref={ref}>
<Text>Hello, React Native!</Text>
</View>
);
};
export default App;Explanation
