Keeps repeating scanning same qr code multiple times

[ZAT90]

When scanning a QR code, it keeps on repeating the scan process. As a result, it keeps giving the same result multiple times as well and keep on vibrating.

What's happening?

When scanning a QR code, if the camera is kept pointed at the qr code, it keeps on scanning for multiple times

How can it be reproduced?

Keep the camera pointed at a specific QR code and do not move the phone

Build details?

1.4.1

Hi, I have a possible solution for this issue. You can use a debounce function to limit the number of calls to the onBarCodeRead method and Please let me know if it solves your problem. Here is the code:

// Import debounce from lodash
import debounce from 'lodash.debounce';

// Define your onBarCodeRead function
const onBarCodeRead = (event) => {
  // Do something with the event object
  console.log(event.type, event.data);
};

// Define a debounced version of your onBarCodeRead function using React.useCallback hook
const debouncedOnBarCodeRead = React.useCallback(debounce(onBarCodeRead, 1000), []);

// Pass the debouncedOnBarCodeRead function as a prop to the QRCodeScanner component
<QRCodeScanner onBarCodeRead={debouncedOnBarCodeRead} />```
