Refine Bowling App in Flutter

I'm looking for assistance in refining my bowling community app, which is built using Flutter and Supabase. The core of the app is already developed, but it needs to be polished and made production-ready.

The key focus areas are improving the user interface design, fixing performance issues, and enhancing navigation and user flow. While I have some design assets ready, additional design work will be necessary to finalize the app's look and feel.

If you have experience with Flutter and Supabase and are skilled in app refinement, I’d love your help to take this project to the next level.
