I need a complete FlutterFlow project that mirrors every screen, flow, and data interaction shown in this reference build: https://www.vibecodeapp.com/s/cmkjidexl002807hq4fm2axo2. Core features that must work out of the box are event registration, real-time race tracking, and results display, all wrapped in a modern, sleek UI consistent with the reference. I will supply brand colours and copy once the base is in place, so please structure styles and components for quick re-theming. The build has to connect to a payment gateway for entry fees and include social media hooks so users can share registration confirmations and final standings. If you normally rely on Stripe and the standard Flutter social plugins that’s perfect, but I’m open to alternatives so long as they are well-documented and can be switched later without code surgery. Deliverable is the full, runnable FlutterFlow project with clean, reusable components, test data, and any custom code snippets already wired up. Push it to a Git repo or hand over the .json export—whichever is easier for you. A brief hand-off note explaining environment variables and API keys will round things off. Once imported, I should be able to hit “Run” and see the reference experience from onboarding to final leaderboard without errors.
