有没有一种方法可以像这样从ThunkAction返回unsubscribeSnapshot的引用：

export const someFetchAction = () => async (dispatch: Dispatch, getState: GetState) => {
  let unsubscribeAuth: UnsubscribeAuth | null = null;
  let unsubscribeSnapshot: UnsubscribeSnapshot | null = null;

  try {
    // Subscribe to auth state changes
    unsubscribeAuth = getAuth().onAuthStateChanged(user => {
      // check if authenticated
    });

    // Subscribe to snapshot updates
    unsubscribeSnapshot = onSnapshot(queryRef, (docsSnapshot) => {
      // dispatches payload data and sets loaded to true
    })

    return {
      unsubscribe: () => {
        if (unsubscribeAuth && unsubscribeSnapshot) {
          unsubscribeAuth();
          unsubscribeSnapshot();
        }
      }
    }

  catch(error) {
    // dispatches error and sets flag error to true
    if (unsubscribeAuth && unsubscribeSnapshot) {
      unsubscribeAuth();
      unsubscribeSnapshot();
    }
  }
}

我尝试从React的useEffect调用它

const { loaded } = useSelector(state => ({
  loaded: state.fireReducer.loaded,
}))

const { someFetchAction } = useActions({
  someFireAction: fireActions.someFireAction,
});

useEffect(() => {
  let actionRef;
  if (!loaded) {
    actionRef = someFireAction();
  }

  return () => {
    actionRef.unsubscribe();
  }
}, [loaded])
