This is a beta release of the CometChat Flutter UI Kit V6. APIs and features may change before the stable release.
The CometChat UI Kit V6 for Flutter is a major architectural evolution of the Flutter Chat UIKit. It provides the same robust set of prebuilt UI widgets that are modular, customizable, and highly scalable, now built on clean architecture with BLoC state management for better testability, maintainability, and performance.

​
What’s New in V6?

  • BLoC State Management – Replaces GetX with flutter_bloc for predictable, testable state.
  • Clean Architecture – Every module follows bloc/ + data/ + domain/ + di/ layers.
  • No DataSource Decorator Chain – Direct static method calls via MessageTemplateUtils replace the 10-layer decorator pattern.
  • Internalized Shared UI – cometchat_uikit_shared is now part of the package, no separate dependency needed.
  • Faster Startup – No extension registration or network calls at init time.

​
Why Choose CometChat UI Kit V6?

  • Rapid Integration – Prebuilt UI widgets for faster deployment.
  • Customizable & Flexible – Modify the UI to align with your brand’s identity.
  • Cross-Platform Compatibility – Works seamlessly across iOS and Android platforms.
  • Scalable & Reliable – Built on CometChat’s robust chat infrastructure.
  • Testable – BLoC pattern with bloc_test and mocktail for comprehensive testing.
  • Better Performance – ~500-2000ms faster startup, no decorator chain overhead.

Integration

​
UI Components (Assemble It Yourself)

A collection of individual widgets—like conversation lists, message lists, message composer, etc.—each with built-in chat logic so you can customize every element. How It Works
  • Import the widgets you need from the UI Kit.
  • Arrange them in your desired layout, applying styling or customization as needed.
  • Each widget integrates with CometChat logic via BLoC and clean architecture layers.
Why It’s Great
  • Flexible Design – You control the final UI arrangement.
  • No Extra Overhead – Implement only the features you need.
  • Modular – Use exactly what you want, when you want.
