Can you exactly specify the logs. Because the qr scan will only we considered successful if it's a valid qr in terms of talawa.

[CyberWake]

Until the same is achieved it will continue to scan once a talawa generated qr is scanned it will automatically stop.

@CyberWake Got it Accutly I scanned QR of url (our heroku api). Can you share formate of valid QR code or demo code ? It keeps scanning it & logs are being generated in terminal. within fraction on time it scan same code multiple times.

This can be fixed using controller.scannedDataStream.first instead of just stream

It would be good if we add pop-up 'you scan wrong code' if user scan invalid code. Whats your opinion @CyberWake ?

[CyberWake]

You need to scan a qr from invite feature exclusive to talawa app from the one of the user who is already logged in and has access to dashboard

[CyberWake]

Logs printed are from the package itself and talking of the poping of the context it does that If you scan a qr from the way I told. QR contains data other than url of the server.

Everything works fine if valid code is provided 👍🏻

[AdityaBirangal]

Can we add pop-up message for invalid code too ?
