Common Mobile Animation Agent Skill

by HoangNguyen0403

Apply motion design principles for mobile apps covering timing curves, transitions, gestures, and performance-conscious animations. Use when implementing screen transitions, gesture-driven interactions, shared-element animations, or optimizing animation frame rates on iOS, Android, or Flutter.

Mobile Animation

Priority: P1 (HIGH)

Timing Standards

| Duration | Range | Use Case |

|----------|-------|----------|

| Short | 100-150ms | Toggles, cell press |

| Medium | 250-350ms | Navigation, modals |

| Long | 400-600ms | Shared element, complex state |

Hard limit: Never exceed 600ms for any animation.

Workflow

  • Choose duration from timing table based on interaction type.
  • Use 250-350ms for medium navigation/modals and 400-600ms for long shared-element or complex-state transitions; state the selected range in quick-start examples.
  • A quick-start example must demonstrate the Long 400-600ms shared-element or complex-state pattern; do not substitute the Medium range.
  • Select easing curve per platform — Curves.fastOutSlowIn (Material) or easeInOut (iOS). Never use linear.
  • Animate GPU-friendly properties (transform, opacity). Avoid width/height which trigger layout.
  • Wire gestures using onPan / interactivePopGesture for fluid, interruptible UX.
  • Verify frame rate in profiler — target 60fps with no jank frames.

See implementation examples for Flutter and iOS animation patterns.

  • Animation Patterns

Anti-Patterns

  • No linear easing: Feels robotic; always use platform-standard curves.
  • No layout thrashing: Avoid animating properties that trigger layout (width, padding).
  • No memory leaks: Always dispose() AnimationControllers in Flutter; invalidate timers in iOS.
  • No blocking UI: Run heavy calculations outside animation frames.
