QR Code Scanner and Generator in Flutter | How to Create QR Code Scanner

Hii, how do i download source code?

Hi! I just want to ask about an error I had in the widget_test.dart

The constructor being called isn't a constructor.dart(const_with_non_const)

Also I am having a hard time allowing the app to use the camera. It shows:

PlatfromException(QRREADER_ERROR, noPermission, null, null)

How can i download generate qr code

Were i can change the options to scan??? (QR, AZTECA,PDF417, etc)

Hello! I wanna ask why mine isn't working?
I did what you instructedbut it didn't work☹
