不存在数据时显示FlatList ItemSeparatorComponent

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

const data = []; // 空数据

const renderItemSeparator = () => (
  <View style={styles.separator} />
);

const MyComponent = () => (
  <FlatList
    data={data}
    renderItem={({ item }) => (
      <View style={styles.item}>
        {/* 渲染列表项的内容 */}
      </View>
    )}
    ItemSeparatorComponent={renderItemSeparator}
  />
);

const styles = StyleSheet.create({
  separator: {
    height: 1,
    backgroundColor: 'gray',
  },
  item: {
    // 列表项的样式
  },
});

export default MyComponent;
