React Native,向useffect hook添加两个return语句

如何在我的返回语句中添加两个返回语句 useEffect 钩我想在我当前的钩子中添加一个事件侦听器。

事件侦听器:

const subscription = AppState.addEventListener("change", nextAppState => {
  if (
    appState.current.match(/inactive|background/) &&
    nextAppState === "active"
  ) {
    console.log("App has come to the foreground!");
  }

  appState.current = nextAppState;
  setAppStateVisible(appState.current);
  console.log("AppState", appState.current);
});

return () => {
  subscription.remove();
};

当前挂钩:

useEffect(() => {

    async function checkRefresh() {
        if (
            daysDiffToNow(lastUpdatedTimestamp) > 0 &&
            appState.current.match(/inactive|background/) &&
            nextAppState === "active"
        ) {
            await onRefreshAppData();
        }
    }
    checkRefresh();

    const updateLastUpdatedTextCallback = (value) => {
        setState((prevState) => ({
            ...
        }));
    };
    const id = setInterval(() => {
        updateLastUpdatedTextCallback(lastUpdatedTimestamp);
    }, TIME_INTERVAL_IN_MILISECONDS);
    return () => clearInterval(id);
}, [lastUpdatedTimestamp]);

const close = () => {
    setState((prevState) => ({
        ...
    }));
};
