INTRODUCTION :

The QR code generator is software that stores data into QR code (for example text or website address). This QR Code Generator Application is basically written in Python by using the below mention modules: 

• kivy                  // $pip install kivy 
• kivymd             // $pip install kivymd
• qrcode             // $pip install qrcode
• plyer                // $pip install plyer

 
NOTE: Please Install these above-mentioned modules before executing the Program.

In this Program, Kivy / Kivymd modules of python are basically used to design an attractive Graphical User Interface for the better experience of the user along with this qrcode is predefined module use to generate QR Code and plyer is basically used to display notifications on the screen.

              

This Application can run Windows, macOS, Linux, and Android Devices. For Android, we have to build this application using Google's Colab or by any Linux system but for windows, macOS, and Linux Os it will work by just having a python interpreter.
