Implement QR codes easily in your React Native app:

Full example use can find here.

import React from 'react';

import { StyleSheet, View, Text } from 'react-native';
import {
  QrCodeSvg,
  plainRenderer,
} from 'react-native-qr-svg';

const SIZE = 170;
const CONTENT = 'Hello world!';

export default function App() {
  return (
    <View style={styles.root}>
      <View style={styles.content}>
        <QrCodeSvg
          style={styles.qr}
          value={CONTENT}
          frameSize={SIZE}
          contentCells={5}
          content={<Text style={styles.icon}>👋</Text>}
          contentStyle={styles.box}
        />
        <QrCodeSvg
          style={styles.qr}
          gradientColors={['#0800ff', '#ff0000']}
          value={CONTENT}
          frameSize={SIZE}
        />
        <QrCodeSvg
          style={styles.qr}
          value={CONTENT}
          frameSize={SIZE}
          contentCells={5}
          content={<Text style={styles.icon}>💻</Text>}
          dotColor="#ffffff"
          backgroundColor="#000000"
          contentStyle={styles.box}
        />
        <QrCodeSvg
          style={styles.qr}
          renderer={plainRenderer}
          value={CONTENT}
          frameSize={SIZE}
        />
        <QrCodeSvg
          style={styles.qr}
          renderer={customRenderer}
          value={CONTENT}
          frameSize={SIZE}
        />
      </View>
    </View>
  );
}

const styles = StyleSheet.create({
  root: {
    flex: 1,
    alignItems: 'center',
    justifyContent: 'center',
  },
  content: {
    flexDirection: 'row',
    flexWrap: 'wrap',
    alignItems: 'center',
    justifyContent: 'center',
  },
  box: {
    alignItems: 'center',
    justifyContent: 'center',
  },
  icon: {
    fontSize: 20,
  },
  qr: {
    padding: 15,
  },
});
