The UI of my FlutterFlow app is already finished; what I now need is the underlying data layer and a fully-working chat experience tied together with Firebase. Here’s exactly what I want to come out of this engagement: • Configure Firebase (Auth, Firestore and Storage) in my existing FlutterFlow project and link it to the already-built screens. • Create the data collections I’ll use: User profiles, Messages and Posts, each with sensible fields and security rules that match best practices. • Implement one-on-one chat, group chat and media sharing so users can exchange text, images and other attachments seamlessly. Typing indicators and read receipts would be great bonuses if they fit naturally with FlutterFlow’s native actions. • Wire up all the queries, actions and state management inside FlutterFlow so everything runs without custom code unless truly necessary. • Provide a short hand-off note or screen recording that shows me where each collection lives, how the chat logic flows and how to extend it later. The UI has no blocking issues, so you can focus strictly on the database structure, rules, and chat logic. If you’ve shipped FlutterFlow + Firebase chat before, this should feel familiar and fast.
