Tip calculator flutter app with source code

Introduction

Tip calculator flutter app is a mobile-based project. It executes on both ios and android platforms. It is easy to use and understand.

We are making a simple tip calculator flutter app in this project. This calculator calculates the total amount with a tip. This project is coded and designed using the flutter framework. Dart is used in coding this application. It has a simple user-friendly interface. The top section has a card that displays the total amount. Below the card, there is a small text area where you can input the total amount.

We are using some colors to make this project more attractive. You can split the bill between your friends. There are two buttons for splitting. One for increasing and another for decreasing. A slider is added to using the tip. You can slide the slider and determine how much tip you are giving. The calculation is done automatically when you slide the slider for tip. See the screenshot below.

Building the tip calculator flutter app project

Tip calculator flutter app is coded using a dart programming language. Dart is a client optimized language for fast app development on any platform. Dart works with widgets. We are using the stateful widget as we have to play with numbers and calculations. You can give random names to this project as a tip calculator, bill splitter…etc. We use containers to contain our widgets and elements.

We are using a hex.dart file to convert the colors into hex format. E.g. #fff, #000, etc. To get the total amount, we perform a small calculation in our code. Elements that we use in our project are Row, column, container, child, children, widget, list view, scaffold etc. Overall the project is simple and easy to use. You will require an emulator to test this project. Download the project and get experienced by yourself.
