在一个事件中反应在后台触发的本机 firebase 多个通知

Question

一次事件触发两次后台通知，不应该发生，我无法检测到问题？我正在使用带有 notifee 的 react native firebase 进行通知..！这是 useEffect 代码，我在其中取消订阅了前台通知侦听器。

useEffect(() => {
    networkCall()
    fetchingUserData().then(() => {
        setIsLoading(false)
    })

    //
    // This is a function for receiving the notification message and displaying notification
    //
    async function onMessageReceivedFore(message: any) {
        onDisplayNotification(message);
        console.log('message received Foreground');
    }
    async function onMessageReceivedBack(message: any) {
        onDisplayNotification(message);
        console.log('message received Background');
    }
    //
    //This is for receiving notification onForeground
    //
    const unsubscribe = messaging().onMessage(onMessageReceivedFore);
    //
    //This is for receiving notification on background
    //
    messaging().setBackgroundMessageHandler(onMessageReceivedBack);

    return () => {
        console.log('component unmount');
        onNotificationInteraction()
        unsubscribe()
    }

}, [])

我同时使用了 onForeground() 通知和 onBackground() 通知，当我删除 onBackground() 通知时，onForeground 方法也在后台触发，所以我在一个事件中收到了两个通知......情况不应该是这样，但现在似乎可以工作......

useEffect(() => {
    networkCall()
    fetchingUserData().then(() => {
        setIsLoading(false)
    })

    //
    // This is a function for receiving the notification message and displaying notification
    //
    async function onMessageReceivedFore(message: any) {
        onDisplayNotification(message);
        console.log('message received Foreground');
    }
    //
    //This is for receiving notification onForeground
    //
    const unsubscribe = messaging().onMessage(onMessageReceivedFore);

    return () => {
        console.log('component unmount');
        onNotificationInteraction()
        unsubscribe()
    }

}, [])
