如何在react-native中将二进制数据显示为图像

import React, { useState } from 'react';
import { View, Image, Button } from 'react-native';
import ImagePicker from 'react-native-image-picker';
import RNFS from 'react-native-fs';

const App = () => {
  const [imageData, setImageData] = useState(null);

  const selectImage = () => {
    ImagePicker.launchImageLibrary({}, (response) => {
      if (response.didCancel) {
        console.log('User cancelled image picker');
      } else if (response.error) {
        console.log('ImagePicker Error: ', response.error);
      } else {
        // Read the image file and convert it to base64
        RNFS.readFile(response.uri, 'base64').then((base64Data) => {
          setImageData(base64Data);
        });
      }
    });
  };

  return (
    <View>
      <Button title="Select Image" onPress={selectImage} />
      {imageData && (
        <Image
          source={{ uri: `data:image/jpeg;base64,${imageData}` }}
          style={{ width: 200, height: 200 }}
        />
      )}
    </View>
  );
};

export default App;
