|
||||
|
||||
## Pre-Deployment Verification
|
||||
|
||||
### ✅ Step 1: Update Dependencies
|
||||
```bash
|
||||
cd /config/Desktop/Github/xtremflow
|
||||
flutter pub get
|
||||
```
|
||||
**Expected Output:** All 13 new packages downloaded and linked
|
||||
- lottie, animations, flutter_animate, percent_indicator, subtitle
|
||||
- dio_downloader, http_client_adapter, and others
|
||||
|
||||
### ✅ Step 2: Verify Compilation
|
||||
```bash
|
||||
flutter pub run build_runner build # if using codegen
|
||||
flutter test # Run existing tests
|
||||
```
|
||||
**Expected Result:** No errors, all tests pass
|
||||
|
||||
### ✅ Step 3: Review New Files
|
||||
Verify all 11 new files exist:
|
||||
|
||||
**Services:**
|
||||
- [ ] `lib/core/services/adaptive_bitrate_service.dart`
|
||||
- [ ] `lib/core/services/network_service.dart`
|
||||
- [ ] `lib/core/services/cache_service.dart`
|
||||
- [ ] `lib/core/services/streaming_optimizer.dart`
|
||||
- [ ] `lib/features/iptv/services/subtitle_service.dart`
|
||||
- [ ] `lib/features/iptv/services/download_service.dart`
|
||||
|
||||
**Providers & Widgets:**
|
||||
- [ ] `lib/features/iptv/providers/recommendations_provider.dart`
|
||||
- [ ] `lib/features/iptv/widgets/quality_selector_widget.dart`
|
||||
- [ ] `lib/features/iptv/widgets/continue_watching_widget.dart`
|
||||
- [ ] `lib/features/iptv/screens/epg_grid_screen.dart`
|
||||
|
||||
**Configuration:**
|
||||
- [ ] `lib/core/config/optimization_config.dart`
|
||||
|
||||
### ✅ Step 4: Update pubspec.yaml
|
||||
Verify these dependencies were added:
|
||||
```yaml
|
||||
dependencies:
|
||||
lottie: ^3.1.0
|
||||
animations: ^2.0.0
|
||||
flutter_animate: ^4.0.0
|
||||
percent_indicator: ^4.1.0
|
||||
subtitle: ^0.0.6
|
||||
dio_downloader: ^2.1.4
|
||||
http_client_adapter: ^1.0.0
|
||||
(and others for UI enhancement)
|
||||
```
|
||||
|
||||
**Status:** Should already be updated ✅
|
||||
|
||||
## Integration Steps
|
||||
|
||||
### Step 1: Initialize Services in Main App
|
||||
|
||||
Add to your `main.dart` or `main_widget.dart`:
|
||||
|
||||
```dart
|
||||
import 'package:xtremflow/core/services/network_service.dart';
|
||||
import 'package:xtremflow/core/services/cache_service.dart';
|
||||
import 'package:xtremflow/core/services/streaming_optimizer.dart';
|
||||
import 'package:xtremflow/core/config/optimization_config.dart';
|
||||
|
||||
void main() {
|
||||
// Calibrate optimization for this device
|
||||
RuntimeOptimizations.calibrateForDevice();
|
||||
|
||||
// Print config summary for debugging
|
||||
OptimizationConfig.printSummary();
|
||||
|
||||
runApp(const MyApp());
|
||||
}
|
||||
```
|
||||
|
||||
### Step 2: Use Adaptive Bitrate in Player
|
||||
|
||||
In your video player screen:
|
||||
|
||||
```dart
|
||||
final qualitySelector = ref.watch(qualitySelectorProvider);
|
||||
|
||||
// Manually change quality
|
||||
qualitySelector.setQuality(QualityLevel.hd720);
|
||||
|
||||
// Enable auto quality
|
||||
qualitySelector.autoQuality = true;
|
||||
```
|
||||
|
||||
### Step 3: Add Recommendation Widgets
|
||||
|
||||
In your home/dashboard screen:
|
||||
|
||||
```dart
|
||||
import 'package:xtremflow/features/iptv/widgets/continue_watching_widget.dart';
|
||||
|
||||
@override
|
||||
Widget build(BuildContext context) {
|
||||
return Column(
|
||||
children: [
|
||||
ContinueWatchingWidget(), // Auto-loads from recommendations
|
||||
SizedBox(height: 20),
|
||||
TrendingWidget(),
|
||||
SizedBox(height: 20),
|
||||
RecentlyAddedWidget(),
|
||||
],
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
### Step 4: Display EPG Grid
|
||||
|
||||
In a dedicated tab or screen:
|
||||
|
||||
```dart
|
||||
import 'package:xtremflow/features/iptv/screens/epg_grid_screen.dart';
|
||||
|
||||
// Use as full-screen widget
|
||||
EpgGridScreen()
|
||||
|
||||
// Or in a tab
|
||||
DefaultTabController(
|
||||
length: 3,
|
||||
child: Scaffold(
|
||||
body: TabBarView(
|
||||
children: [
|
||||
DashboardScreen(),
|
||||
EpgGridScreen(),
|
||||
PlaylistsScreen(),
|
||||
],
|
||||
),
|
||||
),
|
||||
)
|
||||
```
|
||||
|
||||
### Step 5: Add Quality Selector Widget
|
||||
|
||||
In your player overlay:
|
||||
|
||||
```dart
|
||||
import 'package:xtremflow/features/iptv/widgets/quality_selector_widget.dart';
|
||||
|
||||
// Show quality selector dialog
|
||||
QualitySelectorWidget.show(context);
|
||||
|
||||
// Or use as persistent indicator
|
||||
QualityIndicator() // Shows current quality badge
|
||||
```
|
||||
|
||||
## Testing & Validation
|
||||
|
||||
### Unit Tests to Run
|
||||
|
||||
```bash
|
||||
# Test cache service
|
||||
flutter test test/services/cache_service_test.dart
|
||||
|
||||
# Test network service
|
||||
flutter test test/services/network_service_test.dart
|
||||
|
||||
# Test recommendations
|
||||
flutter test test/providers/recommendations_provider_test.dart
|
||||
```
|
||||
|
||||
### Integration Tests
|
||||
|
||||
```bash
|
||||
# Test on web
|
||||
flutter run -d chrome
|
||||
|
||||
# Test on device
|
||||
flutter run
|
||||
|
||||
# Test build
|
||||
flutter build web --web-renderer canvaskit
|
||||
```
|
||||
|
||||
### Performance Verification
|
||||
|
||||
1. **Memory Usage:**
|
||||
- Check before: Use DevTools → Memory tab
|
||||
- Load 50+ items in recommendation widgets
|
||||
- Check after: Should remain under 100MB
|
||||
|
||||
2. **Network Efficiency:**
|
||||
- Monitor: DevTools → Network tab
|
||||
- Load streams multiple times
|
||||
- Verify: Cache hits increase (200% -> 400%)
|
||||
|
||||
3. **Quality Switching:**
|
||||
- Test on various networks (simulate with DevTools)
|
||||
- Quality should auto-adjust within 2-3 seconds
|
||||
- No stuttering during transition
|
||||
|
||||
4. **Download Manager:**
|
||||
- Try downloading 3+ files simultaneously
|
||||
- Pause/Resume operations
|
||||
- Verify: Max 3 concurrent, queue works
|
||||
|
||||
## Deployment to Production
|
||||
|
||||
### Pre-Production Checklist
|
||||
|
||||
- [ ] All new files exist and compile
|
||||
- [ ] Dependencies installed successfully
|
||||
- [ ] Code follows Flutter best practices
|
||||
- [ ] No console errors or warnings
|
||||
- [ ] Performance tests passed
|
||||
- [ ] Device calibration runs successfully
|
||||
- [ ] All widgets display correctly
|
||||
- [ ] Network operations use configured timeout
|
||||
|
||||
### Production Deployment Steps
|
||||
|
||||
1. **Version Bump:**
|
||||
```yaml
|
||||
# In pubspec.yaml
|
||||
version: 1.1.0+11 # was 1.0.0+10
|
||||
```
|
||||
|
||||
2. **Generate Build:**
|
||||
```bash
|
||||
# For web
|
||||
flutter build web --release
|
||||
|
||||
# For desktop
|
||||
flutter build windows --release
|
||||
```
|
||||
|
||||
3. **Deploy:**
|
||||
- Upload to server/CDN
|
||||
- Update index.html manifest if needed
|
||||
- Verify in production environment
|
||||
|
||||
4. **Monitor:**
|
||||
- Track streaming metrics
|
||||
- Monitor for network errors
|
||||
- Collect performance data
|
||||
|
||||
## Rollback Plan (If Needed)
|
||||
|
||||
If issues arise:
|
||||
|
||||
1. **Revert pubspec.yaml** to previous version
|
||||
2. **Remove new service files** (6 files)
|
||||
3. **Run:** `flutter pub get && flutter clean && flutter pub get`
|
||||
4. **Rebuild:** `flutter build web --release`
|
||||
|
||||
The app is designed to be modular, so removals don't break existing code.
|
||||
|
||||
## Configuration Tweaks
|
||||
|
||||
### For Low-End Devices
|
||||
|
||||
```dart
|
||||
RuntimeOptimizations.setDeviceProfile(DeviceProfile.lowMemory);
|
||||
OptimizationConfig.enableAdaptiveBitrate = false; // Use fixed quality instead
|
||||
OptimizationConfig.maxMemoryCacheMb = 50; // Reduce cache
|
||||
```
|
||||
|
||||
### For High-End Devices
|
||||
|
||||
```dart
|
||||
RuntimeOptimizations.setDeviceProfile(DeviceProfile.highPerformance);
|
||||
OptimizationConfig.maxMemoryCacheMb = 200;
|
||||
OptimizationConfig.maxImageCacheMb = 100;
|
||||
OptimizationConfig.defaultQuality = QualityLevel.hd1080;
|
||||
```
|
||||
|
||||
### For Streaming Servers
|
||||
|
||||
```dart
|
||||
OptimizationConfig.connectionTimeout = Duration(seconds: 15);
|
||||
OptimizationConfig.maxRetryAttempts = 5;
|
||||
OptimizationConfig.enableProxySupport = true;
|
||||
```

## Support & Troubleshooting
|
||||
|
||||
### Common Issues
|
||||
|
||||
**❌ Problem:** "Package not found" error
|
||||
```
|
||||
✅ Solution: flutter pub get
|
||||
```
|
||||
|
||||
**❌ Problem:** Quality selector doesn't show options
|
||||
```
|
||||
✅ Solution: Ensure QualitySelector is initialized in provider
|
||||
ref.watch(qualitySelectorProvider)
|
||||
```
|
||||
|
||||
**❌ Problem:** Recommendations show no items
|
||||
```
|
||||
✅ Solution: Verify watch history exists
|
||||
watchHistoryProvider must have data
|
||||
```
|
||||
|
||||
**❌ Problem:** EPG grid loads slow
|
||||
```
|
||||
✅ Solution: Implement lazy loading with PageView
|
||||
Load only visible days, not all 7 at once
|
||||
```
|
||||
|
||||
**❌ Problem:** Memory usage too high
|
||||
```
|
||||
✅ Solution: Call cacheServiceProvider.clearCache()
|
||||
Adjust OptimizationConfig.maxMemoryCacheMb
|
||||
```
