Flutter Expert

This is the comprehensive Flutter skill you'd want if you're building anything beyond a hello world app. It covers the full 2025 ecosystem including Dart 3 patterns, Impeller rendering optimization, and every major state management approach from Riverpod to Bloc. What makes it worthwhile is the depth on platform channels, custom render objects, and the specific guidance on multi-platform deployment across mobile, web, desktop, and embedded. The behavioral traits section is actually useful, pushing const constructors and strategic key usage instead of generic advice. If you're shipping production Flutter apps or migrating to Flutter 3.x, this handles the architecture decisions and performance tuning you'll actually need.
