What is the problem?

Provide an example qr code that you are attempting to scan
catch the result. and show us the result ..
this is my design to build the apps and block i refer in you tube...i want to generate qr and save....i want make google maps qr or anything else
can give idea to make new block or any suggestion
You do not show any blocks/code to generate a qr code. How do you intend to make it, online service or extension?
You need a QR code generator
See these threads to get an idea
