无法对减速器中未安装的组件执行 React state 更新

Question

我在 React Native 应用程序中无法对未安装的组件错误执行 React state 更新我已经经历了几个没有解决问题的可用解决方案，请帮助我了解我在这里做错了什么，

这是我在减速器中尝试过的

const Home = (dispatch) => {
  let isUnmount = false;
  return async () => {
    try {
      const response = await Server.get("/user/home");
      if (!isUnmount) {
        if (response.data.flag == true) {
          dispatch({ type: "StoreData", payload: response.data.data });
        } else {
          dispatch({
            type: "addError",
            payLoad: "Something went wrong please try again",
          });
        }
      }
    } catch (error) {
      dispatch({
        type: "addError",
        payLoad: "Something went wrong please try again",
      });
    }finally{
       isUnmount = true;
    }
  };
};

和组件 useEffect

useEffect(() => {
    let isUnmount = false;
    if (!isUnmount) {
      Home();
    }
    const listner = navigation.addListener("didFocus", () => {
      if (!isUnmount) {
        Home();
      }
    });
    return () => {      
      listner.remove();
      isUnmount = true;
    };
  }, []);
