An Agent Skill that teaches a coding agent which Flutter animation API to reach for, and how to implement it without leaks or silent no-ops.
Demo: https://emadbeltaje.github.io/flutter-animator-example/
Production-style patterns (loading, toggles, lists, navigation, and similar).
| Implicit | Built-in transitions | Hero |
|---|---|---|
 |
 |
 |
| List | Grid | AnimatedSwitcher |
|---|---|---|
 |
 |
 |
| AnimatedIcon | Page transitions |
|---|---|
 |
 |
npx skills add EmadBeltaje/flutter-animatorClaude Code (plugin marketplace — see plugin.json and .claude-plugin/marketplace.json in this repo):
/plugin marketplace add EmadBeltaje/flutter-animator
/plugin install flutter-animator@flutter-animator
Other editors (Cursor, Windsurf, Copilot, and similar): copy skills/flutter-animator/ into that tool’s skills folder (for example .cursor/skills/flutter-animator/). There is no separate marketplace publish for Cursor; manual copy is enough.
Or copy into .claude/skills/, .agents/skills/, or .github/skills/ as needed.
Use this skill whenever you want motion in a Flutter UI and would rather the agent pick the right API than invent a controller from scratch.
| You say | The skill should | Example |
|---|---|---|
| “Make this card expand smoothly” | Implicit AnimatedContainer / AnimatedSize |
Expandable FAQ row, selected product card |
| “Fly this photo into the details screen” | Hero with a unique tag |
Gallery thumbnail → full-screen image |
| “Animate rows being deleted” | AnimatedList / AnimatedGrid |
Dismissible inbox, cart items |
| “Swap the spinner for the content” | AnimatedSwitcher (with keys) |
Loading → data, icon A → icon B |
| “Cross-fade success and error icons” | AnimatedCrossFade |
Form validation, empty vs filled bookmark |
| “Morph menu into close” | AnimatedIcon |
App bar drawer button |
| “Slide this page up” | PageRouteBuilder |
Bottom sheet-style route, onboarding |
| “Snap back after I drag it” | Physics / SpringSimulation |
Draggable card, pull-to-snap |
| “Fade, then slide, then scale” | Staggered animations | First-run hero, list item entrance |
| “Make this smoother” / “add motion” | Decision tree, SDK widgets only | Any widget the user did not name an API for |
In chat, install the skill then just describe the effect. You do not need to name AnimationController or pick a widget — that is the point of the tree.
