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.*

  // Old
  Color(0xFF6C63FF) → AppColors.primary
  Color(0xFFAAAAAA) → AppColors.textSecondary
  

• Update text styles to use theme

  // Old
  style: TextStyle(fontSize: 20)
  
  // New
  style: Theme.of(context).textTheme.titleLarge
  

• Replace spacing values with constants

  // Old
  padding: EdgeInsets.all(16)
  
  // New
  padding: EdgeInsets.all(AppTheme.spacing16)
  

• Update animations to use theme durations

  // Old
  Duration(milliseconds: 300)
  
  // New
  AppTheme.durationMd
  

• Replace old widgets with new ones

  // 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

Testing Requirements:

• Desktop Web

  • Homepage loads correctly
  • Colors match design system
  • Hover animations work smoothly
  • Text contrast is readable
  • Responsive grid adjusts columns
  • No visual glitches

• Mobile Web/Android

  • Layout adapts to small screen
  • Bottom navigation visible
  • Touch targets ≥ 48px
  • Scrolling is smooth
  • No horizontal scroll
  • Text is readable

• Tablet

  • Landscape layout proper
  • Grid shows 3-4 columns
  • Navigation accessible
  • Large text readable

• Animations

  • Hover scale works (1.0 → 1.08)
  • Fade transitions smooth (200ms)
  • Loading spinners display
  • No jank at 60fps

• Colors & Contrast

  • All text ≥ 4.5:1 contrast
  • Focus states visible
  • Gradients render smoothly
  • No color banding

Phase 5: Performance Optimization

• Profile app with DevTools
• Check frame rate (target 60fps)
• Verify image caching works
• Test scroll performance (large lists)
• Check memory usage on low-end device
• Disable shadows during scroll if needed

Phase 6: Deployment

Before deploying to production:

• Run static analysis (flutter analyze)
• Check all tests pass
• Verify no compile warnings
• Test on actual TV resolution (if possible)
• Get design team approval
• Create release notes

Common Implementation Examples

Using Colors

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

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

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

// 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
