Overview

In this project, you will create a simple app that generates QR codes from a short string of text. This tutorial will not go into the finer details of how the input is actually encoded but you can read a good summary about QR codes on Wikipedia . Our app will be simple and have the following features:

• 1. accept text input from the user,
• 2. allow changing the foreground and background colors of the generated code (image), and
• 3. share the code as an image.

As you can see, it is a very small and simple app. Next, let’s setup the project.
