如何在react native中实现本地存储中的条形码解码器

npm install react-native-camera --save

import { RNCamera } from 'react-native-camera';

import React, { Component } from 'react';
import { View, Text } from 'react-native';
import { RNCamera } from 'react-native-camera';

class BarcodeScanner extends Component {
  onBarCodeRead = (event) => {
    console.log(event.data); // 打印扫描到的条形码数据
  }

  render() {
    return (
      <View style={{ flex: 1 }}>
        <RNCamera
          style={{ flex: 1 }}
          onBarCodeRead={this.onBarCodeRead}
        />
      </View>
    );
  }
}

export default BarcodeScanner;

import React from 'react';
import { View } from 'react-native';
import BarcodeScanner from './BarcodeScanner';

const App = () => {
  return (
    <View style={{ flex: 1 }}>
      {/* 其他组件 */}
      <BarcodeScanner />
      {/* 其他组件 */}
    </View>
  );
}

export default App;
