Flutter TikTok-Style Live Battles

I need a seasoned Flutter developer to extend my existing mobile app with a real-time “battle” feature reminiscent of TikTok’s live games. Up to four streamers should be able to go live together while our regular viewers watch, comment, and send in-app gifts (the credit system is already implemented, so you’ll only be calling existing endpoints). Core interaction • Live room: 2–4 hosts share one session, each with selectable virtual backgrounds and three voice filters—Pitch modulation, Echo effects, and Robot voice. • Comment feed: a public stream that appears instantly for every viewer. • Gifting: viewers tap gifts, credits are deducted, animations play, and the running score for each host updates in real time. What I already have • A production Flutter code-base (null-safety, sound architecture). • User accounts, wallet/credit logic, and gift catalog APIs. • Basic single-host live streaming working. What I’m asking you to deliver 1. Multi-host live rooms with smooth switching between 2, 3, or 4 participants. 2. Integration of the three voice effects and virtual background selection per host. 3. A reactive public comment feed tied to our current backend. 4. Real-time gift handling and leaderboard updates using the existing credit system. 5. Clean, well-documented Dart code plus any native modules you add (Android & iOS). Acceptance I’ll consider the job complete when I can: • Start a room, invite up to three others, and stream for 10+ minutes glitch-free. • Toggle each filter during the stream without audio/video desync. • See comments and gift animations appear for all viewers in under one second. • Watch credits deduct correctly and totals match our backend logs. If you have prior experience with WebRTC, Agora, or similar real-time SDKs inside Flutter, please mention it—speed of implementation matters.
