是否通过从另一个文件发送刷新信号来重新呈现FlatList？

import { EventEmitter } from 'events';

const eventEmitter = new EventEmitter();

export const refreshEvent = 'refresh';

export function sendRefreshSignal() {
  eventEmitter.emit(refreshEvent);
}

export function addRefreshListener(callback) {
  eventEmitter.on(refreshEvent, callback);
}

export function removeRefreshListener(callback) {
  eventEmitter.off(refreshEvent, callback);
}

import { useEffect, useState } from 'react';
import { addRefreshListener, removeRefreshListener } from './fileA';

function MyComponent() {
  const [refresh, setRefresh] = useState(false);

  useEffect(() => {
    addRefreshListener(handleRefresh);
    return () => {
      removeRefreshListener(handleRefresh);
    };
  }, []);

  const handleRefresh = () => {
    setRefresh((prevRefresh) => !prevRefresh);
  };

  return (
    <FlatList
      data={...}
      renderItem={...}
      keyExtractor={...}
      refreshing={refresh}
      onRefresh={handleRefresh}
    />
  );
}
