A simple calculator project, this is a ION Mobility Test project. This project is developed within 7 Days given time, the main objective of this project is :
- Simple logic, + (addition) , - (subtraction), * (multiplication), and / (division).
- with Bloc (with Cubit) as a state-management solution.
- can design your own UI, or copy the UI from either iOS or Android’s system calculator apps.
Therefore for the judging Criteria will be based on :
- Correctness
- Code Quality & Readability
Not forget to mention there is also a bonus points on this project that can be achieved :
- Unit Tests
- Widget Tests
- Code Comments
- ReadMe.md
- Custom App Icon
- Creative App Name
- App's UI/UX
- Additional features as you see fit
This project use multiple dependency, for state management this project using flutter_bloc with Cubit approach. For the math evaluation this project use math_expressions so this project can be more focus to manage the interface and states. Other than that for User interface and staggered grid I use flutter_staggered_grid_view to make it more beautiful. Also there is supporting dependency such as intl for number formatting and google_fonts for more beautiful UI.
- flutter_bloc: ^8.1.6
- google_fonts: ^6.2.0
- flutter_staggered_grid_view: ^0.7.0
- intl: ^0.19.0
- math_expressions: ^2.5.0
- Clone this repository
- Make sure to match the SDK first

- (A very Basic) Calculator
- It has 2 theme modes, light and dark

If there is something off with the UI this project is mainly developed using Iphone 15 pro max simulator, and this project might or may be support other screensize / screen category.
