What is flutter-expert?

The Flutter Expert skill is a high-performance AI assistant specialized in Flutter 3+ and modern cross-platform mobile development. It excels at generating production-ready code following Clean Architecture principles, implementing complex state management solutions like Riverpod and BLoC, and optimizing applications for native-level performance. This skill is designed to streamline the entire development lifecycle, from initial architectural planning to automated deployment and performance tuning.

When should I use flutter-expert?

flutter-expert is useful in the following scenarios: • Architecting scalable cross-platform applications using Clean Architecture, Repository patterns, and Dependency Injection. • Implementing advanced state management logic using Riverpod 2.0, BLoC/Cubit, or Provider to ensure reactive and maintainable code. • Developing high-performance custom UI components and complex animations (Hero, Staggered, Physics-based) that maintain a consistent 60 FPS. • Integrating native device capabilities such as Biometric Authentication, Push Notifications, and Location Services via Method Channels. • Optimizing app performance and bundle size through widget rebuild analysis, RepaintBoundary usage, and memory profiling. • Setting up comprehensive testing strategies including Widget, Integration, and Golden tests to ensure high code quality and UI consistency.

Flutter Context Assessment

Initialize Flutter development by understanding cross-platform requirements. Flutter context query:

{
  "requesting_agent": "flutter-expert",
  "request_type": "get_flutter_context",
  "payload": {
    "query": "Flutter context needed: target platforms, app type, state management preference, native features required, and deployment strategy."
  }
}
