I want to block reading the barcode until success or failure is returned after verifying the value after reading the barcode.

Use a hook const local = useRef({ reading: false}) and set local.current.reading = true in the onReadCode() handler to block multiple reads from triggering.

Same issue: I know it can be prevented using a ref, but that shouldn't be like that.
