A lightweight and high-performance QR code generator component for React Native, powered by Skia rendering engine. The package is deeply inspired by react-native-qrcode-svg and it readapts the same concept using Skia capabilities to render the QRCode.

Installation

Before installing the package, make sure you have installed RN Skia.

yarn add @shopify/react-native-skia

Then, you can install the package:

yarn add react-native-qrcode-skia

Usage

You might need a very simple QRCode component in your app and you can achieve that by using the basic props (value and size). Here is an example:

import QRCode from 'react-native-qrcode-skia';

const App = () => {
  return (
    <QRCode
      value="https://patreon.com/reactiive"
      size={200}
    />
  );
};

export default App;

Under the hood, the QRCode is essentially a Skia Path. This means that customization is straightforward using the 'children' prop. Here's an example:

import QRCode from 'react-native-qrcode-skia';

const App = () => {
  return (
    <QRCode
      value="https://patreon.com/reactiive"
      size={200}
      strokeWidth={0.7}
    >
        <SweepGradient
            c={center}
            colors={['cyan', 'magenta', 'yellow', 'cyan']}
        />
        <BlurMask blur={1} style={'solid'} />
        <DashPathEffect intervals={[3.5, 0.5]} />
    </QRCode>
  );
};

export default App;
