直接上代码吧，类似于之前class组件this.setState的第二个callback参数

import React, { useState, useEffect } from 'react';
import fetchData from 'services';

function useList() {
  const [params, setParams] = useState({});
  const [data, setData] = useState({});
  const getData = () => {
    fetchData(params).then(res => {
      setData(res);
    });
  };
  useEffect(() => {
    getData();
  }, []);
  return {
    params,
    setParams,
    data,
    setData,
    getData,
  };
}

function Foo() {
  const { setParams, getData } = useList();
  const handleClick = () => {
    setParams({ mockData: 2333333 });
    // 如何让getData里params是最新的？？？
    getData();
  };
  return (
    <button onClick={handleClick}>click me</button>
  );
}
