react-native-svg-qrcode

A minimal dependency QR Code generator for React Native which works across iOS, Android and Web.

Based on react-native-qrcode-svg but without any dependencies and just a single peer dependency - react-native-svg.

Perfect for folks who already use react-native-svg in their project and want QR code functionality without bloating their bundle size.

Written in TypeScript.

Installation

1yarn add react-native-svg react-native-qrcode-svg

Usage

1const QR_CODE_SIZE = 262;
2const QR_LOGO_SIZE = 70;

4const App = () => {
5  return (
6    <View style={styles.container}>
7      <QRCode
8        size={QR_CODE_SIZE}
9        value={'insert address'}
10        logo={require('../assets/black_r_logo.png')}
11        logoSize={QR_LOGO_SIZE}
