## Next Steps for Developers

### Phase 1: Review & Understanding (Est. 30 min)

- [ ] Read `THEME_INTEGRATION_GUIDE.md` section "Quick Start"
- [ ] Browse `DESIGN_SYSTEM.md` color palette section
- [ ] Review typography examples in `DESIGN_SYSTEM.md`
- [ ] Check widget showcase in `THEME_INTEGRATION_GUIDE.md`

### Phase 2: Update Screens (Depends on scope)

For each screen in `lib/features/iptv/screens/`:

- [ ] Replace old color references with `AppColors.*`
  ```dart
  // Old
  Color(0xFF6C63FF) → AppColors.primary
  Color(0xFFAAAAAA) → AppColors.textSecondary
  ```

- [ ] Update text styles to use theme
  ```dart
  // Old
  style: TextStyle(fontSize: 20)
  
  // New
  style: Theme.of(context).textTheme.titleLarge
  ```

- [ ] Replace spacing values with constants
  ```dart
  // Old
  padding: EdgeInsets.all(16)
  
  // New
  padding: EdgeInsets.all(AppTheme.spacing16)
  ```

- [ ] Update animations to use theme durations
  ```dart
  // Old
  Duration(milliseconds: 300)
  
  // New
  AppTheme.durationMd
  ```

- [ ] Replace old widgets with new ones
  ```dart
  // Old static cards → Use TvModernCard
  // Old channel cards → Use new ChannelCard
  // Hero section → Use HeroCarousel
  // Lists → Use TvHorizontalList or TvChannelGrid
  ```

### Phase 3: Component Integration

For screens not yet using new widgets:

- [ ] `home_screen.dart` - Add HeroCarousel + TvHorizontalList sections
- [ ] `browse_screen.dart` - Switch to TvChannelGrid + TvTopNavBar
- [ ] `details_screen.dart` - Use TvModernCard for related content
- [ ] `player_screen.dart` - Update quality selector colors
- [ ] `settings_screen.dart` - Update to new button styles
- [ ] Mobile screens - Test responsive layouts

### Phase 4: Testing Checklist

- [ ] Check memory usage on low-end device
- [ ] Disable shadows during scroll if needed

### Phase 6: Deployment

Before deploying to production:

## Common Implementation Examples

### Using Colors
```dart
import 'lib/core/theme/app_colors.dart';

// Primary action
FloatingActionButton(
  backgroundColor: AppColors.primary, // Cyan
  child: Icon(Icons.play_arrow),
)

// Text hierarchy
Column(
  children: [
    Text('Title', style: TextStyle(color: AppColors.textPrimary)),
    Text('Subtitle', style: TextStyle(color: AppColors.textSecondary)),
    Text('Helper', style: TextStyle(color: AppColors.textTertiary)),
  ],
)

// Status indicator
Chip(
  backgroundColor: AppColors.success,
  label: Text('Available'),
)
```

### Using Spacing
```dart
import 'lib/core/theme/app_theme.dart';

// Standard padding
Padding(
  padding: EdgeInsets.all(AppTheme.spacing16),
  child: content,
)

// Asymmetric spacing
Container(
  padding: EdgeInsets.symmetric(
    horizontal: AppTheme.spacing32, // 32px left/right
    vertical: AppTheme.spacing16,   // 16px top/bottom
  ),
  child: content,
)

// List spacing
ListView.separated(
  itemCount: items.length,
  separatorBuilder: (_, __) => SizedBox(height: AppTheme.spacing12),
  itemBuilder: (_, index) => ItemCard(items[index]),
)
```

### Using Animations
```dart
import 'lib/core/theme/app_theme.dart';

// Fade transition
FadeTransition(
  opacity: animation,
  child: ContentWidget(),
)

// Scale animation
AnimatedScale(
  scale: isHovered ? 1.05 : 1.0,
  duration: AppTheme.durationMd,
  curve: AppTheme.curveDefault,
  child: Card(),
)

// Smooth page transition
Navigator.push(
  context,
  PageRouteBuilder(
    transitionDuration: AppTheme.durationLg,
    pageBuilder: (_, __, ___) => NextPage(),
    transitionsBuilder: (_, anim, __, child) =>
        ScaleTransition(scale: anim, child: child),
  ),
)
```

### Using Widgets
```dart
// Hero carousel for featured content
HeroCarousel(
  items: featuredShows,
  autoPlay: true,
  height: 400,
)

// Channel grid
TvChannelGrid(
  children: channels.map((ch) => ChannelCard(...)).toList(),
  horizontalSpacing: 20,
  verticalSpacing: 20,
)

// Modern content card
TvModernCard(
  id: show.id,
  title: show.title,
  imageUrl: show.posterUrl,
  rating: '8.7/10',
  year: '2024',
  onPlayTap: () => play(show),
)

// Top navigation
TvTopNavBar(
  title: 'Browse',
  onSearch: () => showSearch(),
  notificationCount: 3,
)
```

## Troubleshooting

### Issue: Colors look wrong/washed out
**Solution:**
- Ensure `scaffoldBackgroundColor: AppColors.background` in theme
- Check for old color overrides in code
- Verify OLED display settings (pure black should be visible)

### Issue: Text is hard to read
**Solution:**
- Use `textPrimary` for main content
- Use `textSecondary` for secondary content (≥ 60% opacity)
- Never use `textTertiary` on dark backgrounds
- Check contrast ratio with tool

### Issue: Cards don't have glass effect
**Solution:**
- Use `GlassContainer`, not plain `Container`
- Ensure `BackdropFilter` is not constrained
- Check `blur` value (default 15.0)

### Issue: Animations are jerky/laggy
**Solution:**
- Use `AppTheme.durationMd` instead of hardcoded values
- Avoid nested `AnimationController`
- Profile with DevTools to find culprit
- Reduce animation complexity on low-end devices

### Issue: Responsive grid not adjusting
**Solution:**
- Use `TvChannelGrid` for automatic behavior
- Check `MediaQuery.of(context).size.width` breakpoints
- Ensure `Expanded` parent for full width
- Test on multiple screen sizes
