I’m ready to move from concept to a working Flutter application that delivers real-time chatting on both iOS and Android. The core features I need you to wire up are: • Real-time text messaging with reliable message delivery • Voice messaging that records, uploads, and plays back smoothly • Social-media-based authentication (Google, Facebook, or similar—feel free to recommend the most straightforward SDK) Because the app must feel identical on iOS and Android, every screen, transition, and permission flow should be implemented once in Flutter and tested on both platforms. I’m open to whichever real-time backend you are most comfortable with—Firebase, Supabase, or a custom WebSocket server—so long as it scales and keeps latency low. Deliverables: 1. Complete Flutter source code ready for Xcode and Android Studio builds 2. Setup instructions for the chosen backend and social login keys 3. A brief README describing how to run the project locally and deploy it to TestFlight and Google Play internal testing If you have previous live chat apps in your portfolio, share a link or short clip so I can gauge the fluidity of your UI and audio handling. Let’s get this chat experience live!

Dear Client, I read "Flutter Live Chat App Build" carefully and understand you want a messaging platform with fast, reliable real-time chat. My hands-on experience with Mobile App Development, Android, iOS Development, Backend Development, Flutter aligns directly with what you need. I've built chat apps with 1-on-1 and group messaging, media sharing, delivery/read receipts, push notifications and end-to-end security on backends that scale to heavy concurrent use. A few quick questions to get us started: 1. Do you need 1-on-1 chat only, or groups, channels and calls too? 2. Should it run on mobile, web, or both? 3. What user scale are you planning for at launch? Thanks & Regards, Deepak
