GradeManager is an software that should help people manage their school grades.
Purpose
The GradeManager project started when I created the Legacy GradeManager with the .Net Framework, just for a friend of mine.
After seeing the demand for applications like Pluspoints, I thought it is time to create an Opensource Cross-Platform application that can handle these things.
Implementation
How already said, the first version of the GradeManager (now called Legacy GradeManager) was created with Windows Forms, a UI Framework from .Net. It is really simple and only compatible with Windows.
The new version of the GradeManager was built using Dart with Flutter as the UI framework, as I wanted the application to be cross-platform, and I already had some experience with Flutter.
Over the whole project I tried to stick to the Flutter standard library, by that I kept most forms and fields a bit standardized. And I also made the configuration human-readable so that anyone can easily make their own changes to the config. Furthermore, I built functions to export the configuration and to import configurations from the Legacy GradeManager and Pluspoints.
Additionally, I’ve created a GitHub Workflow that builds the GradeManager for Windows, Linux, Android and macOS and then adds them to the GradeManager Website. The Windows GradeManager also gets automatically shipped with an automated Inno Setup Installer.
Since I’m not 18 years old right now, I had not the chance to get an Apple/Google Developer account, this is why until now, the App is neither in the App Store nor the Google Play Store.
Lessons Learned
While building the GradeManager I’ve learned many concepts used by UI-Frameworks and how they are solved (e.g. widget-tree, state-management). It has definitely helped me strengthen my skills in Flutter.
In the application there are a lot of weird/confusing patterns, for somehow I did not separate the UI from the actual logic too good.
I suppose it’s not terrible, but that’s the main thing I’d like to improve on, the rest of the application is, in my opinion, pretty well done.
