Objective

Thanks for checking out Boya's front-end coding challenge. Using Dart and Flutter, your task is to build a simple mobile-first calculator app.

Brief

Your challenge is to build out a mobile-first calculator app that lets users perform mathematical operations like addition, subtraction, multiplication, and division.

Tasks

• Implement assignment using:
  • Language: Dart
  • Framework: Flutter
  • Your users should be able to:
    • See the size of the elements adjust based on their device's screen size (mobile only)
    • Perform mathematical operations like addition, subtraction, multiplication, and division
    • Adjust the color theme based on their preference
    • Have their initial theme preference checked using prefers-color-scheme and have any additional changes saved in the browser

Your task is to build out the project to the designs inside the /design folder.

The designs are in JPG static format. Using JPGs will mean that you'll need to use your best judgment for styles such as font-size, padding and margin.

Evaluation Criteria

• Dart best practices
• Completeness: did you complete the features?
• Correctness: does the functionality act in sensible, thought-out ways?
• Maintainability: is it written in a clean, maintainable way?
• Testing: is the system adequately tested?
• Documentation: is the API well-documented?

CodeSubmit

Please organize, design, test and document your code as if it were going into production - then push your changes to the master branch. After you have pushed your code, you may submit the assignment on the assignment page.

Have fun building! 🚀
