Good afternoon 👋
Please I have a problem, I am working on building an automated Attendance System using Qr code for my school project, I have a few setbacks:

1. I used a bottomNavbar it has three pages(Home, Course list, and Menu) I have two users(Student and teacher) they both have different screens for the home and course list but share the same menu page.
-- how do i arrange them or set them so that when you are on the student screen it shows everything student and vice versa (for the home and course list).

2. I used the qr_flutter package to generate qrcode but it only accepts a string.
-- I want to pass multiple arguments like (name:???, age:???) and be able to manipulate them when I scan.

Thank you👍

Hello Johannes, can I use this for user check in and sent it to firebase? but I don't know how to do it :"(

[aligelimat]

I don't know if you read this but i scanned a qr code that should redirect me to other apps, however, when I scanned the QR Code, the scanner turn off but nothing happens. The user still stays in the qr code page. Why does this happen?

[unknownuknown]

it doesn´t work it gives me the value/string -1 why ?
