定义了一个 React 组件 ImageViewer，用于在界面上显示一张图片

import React from 'react';

import { Image, StyleSheet, View } from 'react-native';

type Props = {

  imgSource: any;

};

export default function ImageViewer({ imgSource }: Props) {

  return (

    <View style={styles.container}>

      <Image source={imgSource} style={styles.image} />

    </View>

  );

}

const styles = StyleSheet.create({

  container: {

    alignItems: 'center',

    justifyContent: 'center',

    flex: 1,

    backgroundColor: '#fff',

  },

  image: {

    width: 300,

    height: 300,

    resizeMode: 'contain',

    borderRadius: 10,

  },

});

<ImageViewer imgSource={require('../assets/logo.png')} />
