Flutter Group Chat App

The Challenge

Managing real-time messaging synchronization across hundreds of chat rooms, authenticating users securely using Google Sign-In, and preventing layout jumps during dynamic content loading.

Our Solution

Implemented custom BloC state management in Flutter coupled with Firestore real-time snapshots for sub-100ms message synchronization and secure Firebase Auth rules.

The Result

• Sub-150ms real-time chat sync across multiple concurrently active devices.
• Fully integrated Google Sign-In with customized profile synchronization.
• Optimized Firestore reads by 40% using custom query caching and indexes.
