Build me a Flutter mobile app for a college lost and found system, connected to the existing backend API.

I want students to be able to sign up, log in, report something they lost, report something they found, browse all lost and found listings, open an item to see full details, and submit a claim when they think they found a match. Keep it simple, clean, and easy to use on a phone, with a basic polished UI that feels like a real college app.

Please wire the app to the API properly, handle loading and error states, and make sure the main flows work end to end. Use the current docs online if you need to check anything about Flutter or API integration. This is just for college teaching purposes, so a straightforward implementation is fine, but I do want the app to feel complete and usable.
