I will build real time chat app in flutter with firebase
Shahzaib Hassan
About this gig
Real-time messaging is harder to get right than most developers admit. Message delivery, typing indicators, presence, and push notifications all need to work together smoothly, even under heavy load.
I build production-grade chat features in Flutter using either Firebase (Realtime Database/Firestore) or Socket.IO, depending on your app's scale and requirements not a generic template.
What I Offer:
- 1-on-1 and Group Chat: Real-time messaging with instant delivery.
- Presence and Status: Online/offline and typing indicators.
- Media Sharing: Images, files, and voice messages in chat.
- Push Notifications: FCM integration so users never miss a message.
- Scalable Architecture: Firebase for rapid builds, Socket.IO for custom backend control at scale.
Why Choose Me?
- 4+ years building production Flutter apps, with a specific focus on real-time systems.
- I explain the Firebase vs. Socket.IO tradeoff honestly, based on your use case.
- Clean, documented code your team can maintain going forward.
Whether you need chat added to an existing app or a full messaging app built from scratch, message me with your requirements before ordering so I can scope it accurately.

FAQ
What's the difference between Firebase and Socket.IO, and which will you use for my project?
Firebase is faster to set up and works well for most chat apps. Socket.IO gives you more control over the backend and scales better for apps with heavy real-time traffic. I'll recommend the right one after understanding your requirements.
Can you add chat to my existing Flutter app?
Yes, I regularly integrate chat into apps that weren't built with messaging in mind from the start, without disrupting existing functionality.
Do you handle group chats and media sharing?
Yes, both are included starting from the Standard package group messaging, image/file sharing, and voice messages.
Will the chat system scale if my user base grows?
Yes. For apps expecting high concurrent usage, I build on Socket.IO with an architecture designed for horizontal scaling rather than a quick Firebase prototype.
Do you set up push notifications for new messages?
Yes, FCM (Firebase Cloud Messaging) integration is included so users get notified even when the app is in the background.
