motion-and-haptics
Enforces designed interaction feedback instead of the framework default — every committing interaction acknowledged in the same frame, motion that decorates state but never IS the state (the end state is identical with animations off), a named catalog of moments each declaring its trigger, duration role, haptic slot and reduced-motion fallback at design time, haptics as a HapticTheme event-to-intensity map fired exactly once on the commit frame (never per animation frame, never per coalesced input, never heavyImpact for an error) behind one central toggle, every animation interruptible so a tap resolves it to its end state, a bounded celebration that plays once and never loops or blocks input, an explicit stop condition on every repeating animation (off-route, backgrounded, reduced motion), and feedback on more than one channel so haptics and sound survive reduced motion. Use when adding or tuning an animation, a success or error state, a haptic, a celebration, or a screen transition.
Install
With your agent
Install OMGSkills skill "zakariaf/flutter-skills:skills/motion-and-haptics" into this agent's normal skills directory: call the OMGSkills MCP get_install_plan tool for your agent and run the script it returns (it installs only the pinned commit and verifies SKILL.md), and stop if MCP or the pin is unavailable. Do not overwrite or change existing skills without asking me.
Manual command
git clone https://github.com/zakariaf/Flutter-Skills /tmp/Flutter-Skills && ln -s /tmp/Flutter-Skills/skills/motion-and-haptics ~/.claude/skills/motion-and-hapticsFrom README
Motion and haptics What fires, when, exactly once, and how it degrades. Feedback is the layer users feel rather than read — an app whose taps land, whose errors are felt, and whose success is acknowledged reads as finished; the same app with default Material feedback reads as a prototype. Scope boundary. Motion tokens — duration roles, curve slots, the no-raw-values gate, and resolveMotion collapsing to Duration.zero under reduced motion — are owned by design-system-structure. Painter/ticker mechanics are owned by custom-canvas-and-gestures. Which surface a message uses — loading, empty, error, snackbar, banner, dialog, Undo, and screen-reader announcements — is owned by ui-states-and-feedback. This skill owns the sensory layer those decisions ride on: which moments exist, what each one commits to, how haptics are mapped and fired, and what survives when the animation does not. Non-negotiable rules Every committing interaction is acknowledged in the same frame it happens.
