9 months ago We could try using proguard but I don't think it will affect the application size greatly since Flutter already uses tree shaking. The application size is mainly larger than Android since we use assets like a text classification model, videos and images. We could serve the text classification model via Firebase, but that adds imo a whole list of other issues/potential failure points

9 months ago @Garfield96 in the age of basically free storage, free wifi and all phones having hundreds of GB of storage, and 100MB for an app being the average.
⇒ reduction not really necessary

8 months ago Here is some actual data from the android version:
flutter build appbundle --analyze-size --target-platform android-arm
Font asset "MaterialIcons-Regular.otf" was tree-shaken, reducing it from 1645184 to 9264 bytes (99.4% reduction). Tree-shaking can be disabled by providing the --no-tree-shake-icons flag when building your app.

A summary of your AAB analysis can be found at: /home/kb/.flutter-devtools/aab-code-size-analysis_01.json
To analyze your app size in Dart DevTools, run the following command:
dart devtools --appSizeBase=aab-code-size-analysis_01.json
✓ Built build/app/outputs/bundle/release/app-release.aab (55.3MB).So we could move the video to the backend and reduce the assets by 10MB. I think anything below 50 MB is reasonable.

Is your feature request related to a problem? Please describe. The campus-flutter app currently has a size of ~80mb. Compared to the campus-android app (~29mb), this is very large. It would be beneficial to shrink the app size, to take up less space on the user device, to speed-up app downloads and, potentially, to improve the performance of the app itself.
Describe the solution you'd like The campus-android app uses proguard to shrink the binary. For Android builds, this would be also applicable to campus-flutter. There are several blog posts describing how to decrease binary size for flutter apps, which might also help.
Describe alternatives you've considered None
Additional context To keep the size under control, it would be possible to check the size in the CI and automatically add a comment to a new PR describing the increase/decrease in size.
