React组件中监听函数获取不到最新的state问题

export default function Travel(props) {
    const divRef = useRef(null)
    const [count, setCount] = useState(0)
    const handleClick = () => {
        console.log('click',count);
    }
 
    useEffect(() => {
        window.addEventListener('click', handleClick)
        return () => {
            window.removeEventListener('click', handleClick)
        }
    },[])
    console.log('out',count);
 
 
    return (
        <div ref={divRef} >
            <button onClick={() => {
        setCount(count => count + 1)
 
            }}>点击</button>
        </div>
    )
}

const [flag,setFlag] = useState(false);
  
  const onClick = ()=>{
    setFlag(!flag)
    console.log(flag)
  }
  
  useEffect(() => {
    document.addEventListener('click',onClick)
  }, []);

useEffect(() => {
    window.addEventListener('click', handleClick)
    return () => {
        window.removeEventListener('click', handleClick)
    }
},[count])

const stateRef = useRef(0)
const [state,setState] = useState(stateRef.current);
 
const Function = ()=>{
    let data = JSON.parse(JSON.stringify(stateRef));
    /*功能*/
    stateRef.current = newData;
    setState(stateRef.current)
}  

const stateRef = useRef(null);
 
useEffect(() => {
    if (
      !stateRef.current ||
      (reduxState &&
        JSON.stringify(reduxState) !== JSON.stringify(stateRef.current) &&
        JSON.stringify(reduxState.id) !== JSON.stringify(stateRef.current?.id))
    ) {
      sstateRef.current = JSON.parse(JSON.stringify(reduxState));
    }
  }, [reduxState]);
