如何在react native中使用Expo共享QRCode？

npm install -g expo-cli

expo init MyProject

cd MyProject
npm install expo-qrcode

import { BarCodeScanner } from 'expo-barcode-scanner';

render() {
  return (
    <View style={styles.container}>
      <BarCodeScanner
        onBarCodeScanned={this.handleBarCodeScanned}
        style={StyleSheet.absoluteFillObject}
      />
    </View>
  );
}

handleBarCodeScanned = ({ type, data }) => {
  // 处理扫描结果
  console.log(`扫描类型: ${type}`);
  console.log(`扫描数据: ${data}`);
}

expo start
