shatattya/my-uni-app ? reverse-engineered prompt

Build me a sleek campus companion app for BGC Trust University that helps students and teachers stay on top of everything in one place.

I want an offline first Flutter app with a polished blue look, responsive on phones and tablets, where users can check class routines even without internet, then sync automatically when back online. It should also show university notices in real time, with push notifications that can be filtered by semester and section. Add a hidden admin area for managing routine data and seeing basic system info. Include a simple auto update flow so the app can check for new versions online and prompt users to update. Use Firebase for auth, notices, and messaging, and keep local data stored so the app still works smoothly offline. If you need to look up current docs online for Flutter or Firebase setup, go ahead.
