Barcode Scanner component behaviour in snack

I’m very new to this whole eco system so maybe I just don’t understand how it’s supposed to work. Why does the alert keep showing if I keep it pointed at a QR code? I was expecting it to stop after the first successful scan?

Here is the snack I’m using.

Have you solve this?

As a temporary solution… you could place the camera inside a modal. In this case you have to activate the modal to display the camera capture area, after capturing a barcode, automatically hide the modal… Not a bad improvisation.
