main.dart: It is the main entry point of our app. It defines the basic structure and primary navigation of the app.

‌ In our case, we have a side menu navigation. In this file, we have defined which page would be the first one, the options and shipping of the side menu. It also helps in notifying when the platform gets ready.

Common:

It contains standard files which we are using in our project. In this case, we have defined a constant variable which is used within the app and is easy to change variable value.

base_url: 'https://restaurantrestapi.herokuapp.com/' // you can add your own database URL

Pages:

Each page has it’s a folder. And within that folder, you will find every related file for that page. This includes UI, and it is connected with the service page.

‌ Let’s get through the cart page.

Service:

Style:

t contains standard style file which we are using in this project. In our case, we have defined all the colors used within the app and is easy to change the color so you can play around and try different color schemes.
