i want to be able to generate a barcode on screen from a storage variable but dont know where to start. any advice on tutorials?
1) find framework which generates qrcode
2) create Javascrip file in the app project
3) paste framework file in just created js file
4) add, for test purposes, button you start page
5) for button click event add js code, which will invoke framework
6) save or paste result somewhere for instance in console.
