CalcSim

CalcSim is a cross platforms mobile application that simulates the functionalities of a calculator. In addition, CalcSim also supports modulus calculations which is convenient mostly in converting numbers between different bases.

Mobirise

As the application is a calculator simulator, it provides all basics functionalities of a calculator. Besides, it also provides a functionality of calculating modular, which is convenient as it's not on every calculator.

Summary

  • Context

    • CalcSim is a personal project developed during the Spring of 2021. The application was implemented with Flutter and Dart language to support both user interface and back-end logic of handling calculations. This application makes uses of a very simple library provided by Dart, which is the materials library to support the UI display.

  • Role

    • As CalcSim is a personal project, I took the steps of designing and implementing the graphical user interface then coming up with the logic to parse and handle inputted calculations.

  • Delivery

    • The project is delivered will all basics functionalities of calculating addition, subtraction, multiplication, division and modular. The challenges while I was working this project were to sanitize user's inputs, parsing the calculation correctly and display it synchronously on the graphical interface.

    Technologies

    Flutter/Dart

    Supports the logic of parsing user's input, calculate and display of the application.

    Analysis

  • Strengths

    • I evaluate that I did well on learning and following the Dart/Flutter's structures and layouts of the widgets. I also did well on parsing user's input to handle the calculations correctly. Beside technical skills and implementation, I also did well on learning a new programming language and the concept of cross platform applications.

  • Skills Reflection

    • By working on this personal project, I was able to gain my knowledge on the Flutter/Dart programming language and the concept of cross platform applications. I was also given an opportunity to learn and apply the structures of widgets, which I did not have a chance to touch on in school. Besides gaining new skills and knowledge, I also improved my old skills of problem solving and basics programming.

  • Project Reflection

    • What went well while working on this project was the experience of learning new programming language and the concept of cross platform applications. I was able to learn new technologies to enlarge my knowledge and better up my career path. From the experience I had while working on this project, I would improve the knowledge on how to change the font and color of widgets as it would help styling the application better.
