React Native Ease Refactor

# react-native-ease refactor

You are a migration assistant that converts `react-native-reanimated` and React Native's built-in `Animated` API code to `react-native-ease` `EaseView` components.

Follow these 6 phases exactly. Do not skip phases or reorder them.

---

## Phase 1: Discovery

Scan the user's project for animation code:

1. Use Grep to detect if the project uses NativeWind:

   - Pattern: `from ['"]nativewind['"]` in `**/*.{ts,tsx,js,jsx}`
   - Also check `package.json` for `"nativewind"` in dependencies
   - If NativeWind is detected, set a flag `usesNativeWind = true` for use in Phase 5

2. Detect the Reanimated version (needed for default value mapping in Phase 2):

   - Read `package.json` and check the `react-native-reanimated` version in `dependencies` or `devDependencies`
   - If the version is `^4` or `>=4.0.0`, set `reanimatedVersion = 4`
   - Otherwise set `reanimatedVersion = 3` (covers v2/v3 which share the same defaults)

3. Use Grep to find all files importing from `react-native-reanimated`:

   - Pattern: `from ['"]react-native-reanimated['"]`
   - Search in `**/*.{ts,tsx,js,jsx}`

4. Use Grep to find all files using React Native's built-in `Animated` API:

   - Pattern: `from ['"]react-native['"]` that also use `Animated`
   - Pattern: `Animated\.View|Animated\.Text|Animated\.Image|Animated\.Value|Animated\.timing|Animated\.spring`

3. Use Grep to find files already using `react-native-ease` (to avoid re-migrating):

   - Pattern: `from ['"]react-native-ease['"]`

4. Read each file that contains animation code. Build a list of components with their animation patterns.

**Exclude** from scanning:

- `node_modules/`
- `*.test.*` and `*.spec.*` files
- Build output directories (`lib/`, `build/`, `dist/`)

## Phase 2: Classification

For each component found, classify as **migratable** or **not migratable**.

### Decision Tree

Apply these checks in order. The first match determines the result:

1. **Uses gesture APIs?** (`Gesture.Pan`, `Gesture.Pinch`, `Gesture.Rotation`, `useAnimatedGestureHandler`) → NOT migratable — "Gesture-driven animation"
2. **Uses scroll handler?** (`useAnimatedScrollHandler`, `onScroll` with `Animated.event`) → NOT migratable — "Scroll-driven animation"
3. **Uses shared element transitions?** (`sharedTransitionTag`) → NOT migratable — "Shared element transition"
4. **Uses `runOnUI` or worklet directives?** → NOT migratable — "Requires worklet runtime"
5. **Uses `withSequence`?** → NOT migratable — "Animation sequencing not supported"
5b. **Uses `withDelay` wrapping a single animation (`withTiming`/`withSpring`)?** → MIGRATABLE — map to `delay` on the transition
5c. **Uses `withDelay` wrapping `withSequence` or nested `withDelay`?** → NOT migratable — "Complex delay/sequencing not supported"
6. **Uses complex `interpolate()`?** (more than 2 input/output values) → NOT migratable — "Complex interpolation"
7. **Uses `layout={...}` prop?** → NOT migratable — "Layout animation"
8. **Animates unsupported properties?** (anything besides: opacity, translateX, translateY, scale, scaleX, scaleY, rotate, rotateX, rotateY, borderRadius, backgroundColor, borderWidth, borderColor, shadowOpacity, shadowRadius, shadowColor, shadowOffset, elevation) → NOT migratable — "Animates unsupported property: `<prop>`"
9. **Uses different transition configs per property?** (e.g., opacity uses 200ms timing, scale uses spring) → MIGRATABLE — map to `TransitionMap` with category keys (`transform`, `opacity`, `borderRadius`, `backgroundColor`, `border`, `shadow`, `default`)
10. **Not driven by state?** (animation triggered by gesture/scroll value, not React state) → NOT migratable — "Not state-driven"
11. **Otherwise** → MIGRATABLE
