Motion Clinic — Flutter animation & motion review

Paste your Flutter animation code — the widgets and State classes that own AnimationControllers, implicit Animated* widgets, Hero pairs, custom route transitions, gesture-driven physics — and get a senior Flutter engineer's motion review: a posture verdict, the widget and controller inventory, prioritized findings across lifecycle, strategy, performance, correctness, transitions, physics and accessibility — each with a corrected Dart fragment — plus quick wins, focus areas, and a free instant prescan that flags undisposed controllers, missing vsync, Timer-driven frame math, whole-tree setState listeners, duplicate Hero tags and more before you run anything. Derived from the @flutter/flutter-animating-apps skill (BSD-3-Clause, flutter/agent-plugins).

Every public app is built from a security-scanned skill and must pass a clean scan — skill and frontend — before it can be listed. Have a skill of your own? Turn it into an app — or read the step-by-step walkthrough.
