## Advanced Features

### Spring Animations

The component uses spring-based animations for a natural, responsive feel that mimics the satisfying button press experience found in apps like Duolingo:

```tsx
// Custom spring configuration (built-in)
<AnimatedButton
  title="Spring Button"
  onPress={() => {}}
  // Uses: stiffness: 300, damping: 20, mass: 0.4
/>
```

### RTL Language Support

Automatically detects and adapts to right-to-left languages:

```tsx
// Icon automatically swaps to right side in RTL languages
<AnimatedButton
  title="Continue"
  icon="arrow-right"
  // iconPosition not specified - auto-detects RTL
/>
```

### Accessibility Features

Enhanced accessibility with proper labels, hints, and touch targets:

```tsx
<AnimatedButton
  title="Accessible Button"
  onPress={() => {}}
  accessibilityLabel="Primary action button"
  accessibilityHint="Double tap to perform the main action"
  hitSlop={{ top: 10, bottom: 10, left: 10, right: 10 }}
  testID="primary-button"
/>

// Reduced motion support for accessibility
<AnimatedButton
  title="Static Button"
  onPress={() => {}}
  disableAnimations={true} // No animations for users who prefer reduced motion
/>
```

### Press Lock Mechanism

Prevents accidental double-presses with configurable timing:

```tsx
<AnimatedButton
  title="Protected Button"
  onPress={() => handleExpensiveOperation()}
  // Automatically prevents rapid double-presses
/>
```

### Reduced Motion Support

Respects user accessibility preferences by allowing animation disabling:

```tsx
<AnimatedButton
  title="Accessible Button"
  onPress={() => {}}
  disableAnimations={true} // Respects user's reduced motion preference
/>
```

## Haptic Feedback

The component uses Expo Haptics for tactile feedback. You can customize the intensity:

- `'Light'` - Subtle feedback
- `'Medium'` - Moderate feedback  
- `'Heavy'` - Strong feedback (default)

```tsx
<AnimatedButton
  title="Light Haptic"
  onPress={() => {}}
  hapticStyle="Light"
/>
```

## TypeScript Support

This package is written in TypeScript and includes full type definitions. You'll get excellent IntelliSense support and type safety:

```tsx
import { AnimatedButton, AnimatedButtonProps, IconType, HapticStyle, ButtonType, IconPosition } from 'react-native-3d-animated-buttons';

// All props are fully typed
const MyButton: React.FC = () => {
  const handlePress = (): void => {
    console.log('Button pressed!');
  };

return (
    <AnimatedButton
      title="Typed Button"
      onPress={handlePress}
      hapticStyle="Medium" // Autocomplete available: 'Light' | 'Medium' | 'Heavy'
      icon="apple" // Autocomplete available: 'apple' | 'google' | 'phone' | 'facebook'
      type="capsule" // Autocomplete available: 'normal' | 'capsule'
      iconPosition="right" // Autocomplete available: 'left' | 'right'
    />
  );
};
```

## Test App

This package includes a comprehensive test app demonstrating all features:

```bash
cd test-app
npm install
npx expo start
```

The test app showcases:
- ✅ **All button features** - Basic, social, icons, types, loading
- ✅ **Icon positioning** - Left/right placement examples
- ✅ **Font customization** - Typography styling options
