What is the method to override props in a React Native library

Question

Can you tell me What is the method to override props in a React Native library?

Answer 1

In React Native, if you want to override the default props of a component from an external library without modifying the library's source code, you can create a wrapper component that sets the desired default prop values. This approach allows you to customize the component's behavior while maintaining the integrity of the original library.

Here's how you can implement this:

Create a Wrapper Component: Define a new component that wraps the original component from the library.

Set Default Props in the Wrapper: Within your wrapper component, specify the default prop values you wish to override.

Render the Original Component with Overridden Props: Use the spread operator to pass all received props to the original component, ensuring that any props provided during usage can still override the defaults you've set in the wrapper.

Here's an example:

Usage:

import React from 'react';

import { View } from 'react-native';

import QRCodeScannerWrapper from './QRCodeScannerWrapper'; // Adjust the import path accordingly

const App = () => (

  <View style={{ flex: 1 }}>

    <QRCodeScannerWrapper

      // You can still override props here if needed

      onRead={(e) => console.log('QR code scanned!', e)}

    />

  </View>

);

export default App;
