Flutter: Implementing login authentication using QR code connected to the firebase.

I am planning to implement a mobile app that cater it's user to authenticate using QR code. As of today, I have no idea on how to implement this feature (challenging for me). Very much appreciated if someone answers my question. I am beginner on this tool. I hope you can give me sample code or direct me to a tutorial that implements something relevant to my query.

Thank you. :)
