Flutter — Cart Calculator App: Part 1
This one is for beginners.
Today, I am going to use my basic Flutter development skills required to make a shopping cart calculator app.
The idea is that the users can add items to a list while they are shopping and even before shopping. Each item will be given some price. This way the users can calculate their sum before reaching the checkout counter to make sure they are under budget.
This app will use a few external packages and data structures. I will make sure to explain each concept along the way.
I assume that you have completed your Flutter development setup. So, let’s create a new project. For “ease”, I am going to use a terminal. Open command prompt from the start menu.
