我有一个节列表，页脚有一个ActivityIndicator。即使列表呈现了每一项，ActivityIndicator也不会消失。数据是本地数据。
我知道我必须使用React Hook，所以我创建了_handleLoadMore（）来更新状态，但我不知道如何检测列表是否已结束。
这是我的密码

import {
  View,
  Text,
  StyleSheet,
  SectionList,
  ActivityIndicator,

export default function TransactionHistoryList({data}: {data: any}) {

  const [loadMore, setLoadMore] = useState('true')

  const _handleLoadMore = () => {
   //what to put here
  }

  const extractKey = ({
    id,
  }: {
    id: any;
    name: any;
    accountNumber: any;
    type: any;
    amount: any;
  }) => id;

  const renderSeparator = () => {

    return (
      <View
        style={{
          height: 1,
          width: '94%',
          backgroundColor: '#000',
          alignSelf: 'center',
        }}
      />
    );
  };

  const footerComponent = () => {
    if (!_handleLoadMore) return null;
