Flutter Live Chat App Build

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!
