我想避免不必要的重新呈现，所以我使用useMemo。
但我收到了以下错误消息：

TypeError: renderItem is not a function. (In 'renderItem(props)', 'renderItem' is an instance of Object)

编码：

import * as React from 'react';
import { StyleSheet, Text, View, TouchableOpacity, Image, Dimensions, FlatList } from 'react-native';
import faker from 'faker';

const { width, height } = Dimensions.get('window');

const Advertising = () => {
  const data = [
    { id: '1', name: 'Jens', image: faker.image.avatar() },
    { id: '2', name: 'Günther', image: faker.image.avatar() }
  ];

  const renderItem = React.useMemo(() => {
    return (
      <View>
        <Text>Hello</Text>
      </View>
    )
  }, [data]);

  return (
    <FlatList
      data={data}
      keyExtractor={item => Math.random(100).toString()}
      renderItem={renderItem}
    />
  )
};

const styles = StyleSheet.create({
  container: {
    flex: 1,
  }
});

export default React.memo(Advertising);
