The code from the camera is scanned several times in a row

[suprunchuk]

Hi. I implemented a code scanner using expo-camera. Everything works fine. But when scanning, I have 3-5 codes displayed in the console at once in a millisecond. Why does the camera scan several times in a millisecond at once and how to get rid of it??? When I have an invalid code scanned, a toast notification appears, but it appears as many times as the code was scanned unsuccessfully. Accordingly, the vibration in case of unsuccessful scanning is triggered from 3 to 5 times. How do I do a scan once?? Scan once and close the scanner.

export default function QRScannerCamera({ navigation }) {
    const toggleFlashlight = () => {
        setIsFlashlightOn(!isFlashlightOn);
        Haptics.impactAsync(Haptics.ImpactFeedbackStyle.Light);
    };

    const getSIFromTheDatabaseByCode = async (barcodeData) => {
        if (!apiUrl || !scannedText) {
            console.error("apiUrl or text is missing.");
            return;
        }

        setLoading(true);

        try {
            const response = await fetch(`${localAdres}/code/${barcodeData}`);
            if (!response.ok) {
                Haptics.notificationAsync(Haptics.NotificationFeedbackType.Error);
                setDataFromServer([]);
                return;
            }
            const json = await response.json();
            if (!json) {
                console.error("Err");
                setDataFromServer([]);
                return;
            }
            Haptics.notificationAsync(Haptics.NotificationFeedbackType.Success);
            setDataFromServer(json);
            return Object.keys(json).length > 0;
        } catch (error) {
            console.error("An error occurred during the request", error);
            return false;
        } finally {
            setLoading(false);
        }
    };

    const handleBarCodeScanned = async ({ type, data }) => {
        setScannedText(data);
        console.log("NEW code scanned, Type: " + type + " Data: " + data + "Time scan: " + new Date());

        try {
            const result = await getSIFromTheDatabaseByCode(data);
            if (result) {
                setIsFlashlightOn(false);
                setIsModalVisible(true);
            } else {
                navigation.navigate("Scanner Stack");
                ToastAndroid.show("No data!", ToastAndroid.SHORT);
            }
        } catch (error) {
            ToastAndroid.show("Err!", ToastAndroid.SHORT);
        }
    };

    return (
        <View style={{ flex: 1, justifyContent: "center" }}>
            {isCameraVisible && !isModalVisible ? (

At 16:34:08, the code was scanned 6 times in one millisecond

I need the code to be scanned once when pointing the camera at it. help
