On audit: Discarded multi-provider fixes - reverting to master

Commit 0263c75 reduced defaultHomeRowOrder to 3 rows but also
introduced a bug where _filteredRowOrder only showed rows currently
in _homeRowOrder. This made most row options invisible in settings.

Added _allAvailableRows constant (13 rows) and modified _filteredRowOrder
to show all available static rows regardless of their current enabled state.

Users can now see and toggle all 13 home screen rows:
- 3 enabled by default (recent albums, discover artists, discover albums)
- 10 disabled by default (all other rows)

Fixes regression from commit 0263c75 (Feb 5, 2025)

+# Ensemble Flutter Music Application - Codebase Audit Report
+
+**Generated:** 2026-02-07
+**Project Location:** `/home/chris/Ensemble`
+**Code Size:** ~6,180 lines in main provider, ~50K+ total lines
+**Flutter Version:** 3.0+
+**Auditor:** Claude Code Analysis
+
+---
+
+## Executive Summary
+
+This comprehensive audit examined the Ensemble Flutter music streaming application for security vulnerabilities, performance issues, code quality concerns, and architectural problems. The audit identified **23 distinct issues** across severity levels.
+
+### Severity Breakdown
+- **Critical:** 2 issues
+- **High:** 6 issues
+- **Medium:** 10 issues
+- **Low:** 5 issues
+
+### Overall Health Assessment: **GOOD** (with areas for improvement)
+
+The codebase demonstrates:
+- ✅ Strong secure storage practices (flutter_secure_storage with encryptedSharedPreferences)
+- ✅ Comprehensive dispose() cleanup across widgets
+- ✅ Good mounted check usage in most async operations
+- ⚠️ One critical file requiring splitting (6,180 lines)
+- ⚠️ Some timer callback issues
+- ⚠️ Several .then() chains that should use async/await
+
+---
+
+## 1. CRITICAL ISSUES
+
+### 1.1 Massive Single File - `music_assistant_provider.dart`
+**File:** `/home/chris/Ensemble/lib/providers/music_assistant_provider.dart`
+**Lines:** 6,180
+**Severity:** Critical
+**Category:** Maintainability
+
+**Description:**
+The main provider file is extremely large (6,180 lines), making it difficult to navigate, test, and maintain. This violates single responsibility principle and increases the risk of merge conflicts.
+
+**Recommendation:**
+Split into smaller focused providers:
+- `MusicAssistantProvider` (core coordination)
+- `PlayerStateProvider` (player management)
+- `LibraryStateProvider` (library data)
+- `ConnectionProvider` (already exists but not fully utilized)
+
+**Impact:** High complexity, difficult onboarding, increased bug risk
+
+---
+
+### 1.2 Empty setState() Call
+**File:** `/home/chris/Ensemble/lib/screens/debug_log_screen.dart:367`
+**Severity:** Critical
+**Category:** Performance
+
+**Code:**
+```dart
+onPressed: () {
+  setState(() {});
+  if (_scrollController.hasClients) {
+    _scrollController.animateTo(...)
+  }
+},
+```
+
+**Description:**
+An empty setState() triggers a complete widget rebuild without any state changes, wasting CPU cycles.
+
+**Recommendation:**
+```dart
+onPressed: () {
+  if (_scrollController.hasClients) {
+    _scrollController.animateTo(...)
+  }
+},
+```
+
+Or if state update is needed:
+```dart
+onPressed: () {
+  setState(() => _lastRefreshTime = DateTime.now());
+  if (_scrollController.hasClients) {
+    _scrollController.animateTo(...)
+  }
+},
+```
+
+---
+
+## 2. HIGH SEVERITY ISSUES
+
+### 2.1 Timer Callback Without Mounted Check
+**File:** `/home/chris/Ensemble/lib/providers/sleep_timer_provider.dart:76-77`
+**Severity:** High
+**Category:** Performance/Stability
+
+**Code:**
+```dart
+_sleepTimerDisplayTimer = Timer.periodic(const Duration(seconds: 1), (_) {
+  notifyListeners(); // Update UI with remaining time
+});
+```
+
+**Description:**
+Timer callback calls notifyListeners() without checking if the widget is still mounted. If the provider is disposed but timer fires, it could cause issues.
+
+**Recommendation:**
+Add a flag to track disposal state:
+```dart
+bool _disposed = false;
+
+_sleepTimerDisplayTimer = Timer.periodic(const Duration(seconds: 1), (_) {
+  if (!_disposed) {
+    notifyListeners();
+  }
+});
+
+@override
+void dispose() {
+  _disposed = true;
+  _cancelInternal();
+  super.dispose();
+}
+```
+
+---
+
+### 2.2 Multiple .then() Chains (Should Use async/await)
+**Files:**
+- `/home/chris/Ensemble/lib/screens/playlist_details_screen.dart:598`
+- `/home/chris/Ensemble/lib/widgets/expandable_player.dart:468, 502, 521, 577, 601, 1644, 1773`
+- `/home/chris/Ensemble/lib/widgets/playlist_card.dart:258`
+- `/home/chris/Ensemble/lib/widgets/podcast_card.dart:264`
+- `/home/chris/Ensemble/lib/widgets/player/queue_panel.dart:212`
+- `/home/chris/Ensemble/lib/widgets/player/player_reveal_overlay.dart:83, 115, 191`
+- `/home/chris/Ensemble/lib/widgets/album_card.dart:335`
+- `/home/chris/Ensemble/lib/widgets/artist_card.dart:321`
+- `/home/chris/Ensemble/lib/screens/new_library_screen.dart:1213`
+
+**Severity:** High
+**Category:** Code Quality
+
+**Example:**
+```dart
+// Current (.then pattern)
+maProvider.addTracksToQueue(player.playerId, _tracks).then((_) {
+  if (mounted) {
+    ScaffoldMessenger.of(context).showSnackBar(...);
+  }
+});
+```
+
+**Recommendation:**
+```dart
+// Preferred (async/await)
+try {
+  await maProvider.addTracksToQueue(player.playerId, _tracks);
+  if (mounted) {
+    ScaffoldMessenger.of(context).showSnackBar(...);
+  }
+} catch (e) {
+  // Handle error
+}
+```
+
+**Impact:** async/await provides better error handling and readability
+
+---
+
+### 2.3 TODO Comments for Unimplemented Features
+**Files:**
+- `/home/chris/Ensemble/lib/providers/music_assistant_provider.dart:1418, 1424`
+- `/home/chris/Ensemble/lib/screens/audiobook_detail_screen.dart:351, 402`
+- `/home/chris/Ensemble/lib/screens/queue_screen.dart:283`
+
+**Severity:** Medium-High
+**Category:** Functionality
+
+**Description:**
+Important features are marked as TODO but not implemented:
+- Playlist modification functionality
+- Server-side audiobook progress updates
+- Queue item removal via API
+
+**Recommendation:**
+Create GitHub issues for these features and track implementation progress.
+
+---
+
+### 2.4 Unused Dependencies Detection
+**File:** `/home/chris/Ensemble/pubspec.yaml`
+**Severity:** High (if truly unused)
+**Category:** Bundle Size
+
+**Potential Unused Packages:**
+- `package_info_plus` (used in debug_logger.dart - ✅ KEEP)
+- `device_info_plus` (used in debug_logger.dart - ✅ KEEP)
+- `share_plus` (used in debug_log_screen.dart - ✅ KEEP)
+- `url_launcher` (used in settings_screen.dart - ✅ KEEP)
+
+**Conclusion:** All listed packages are actually in use. No action needed.
+
+---
+
+### 2.5 Duplicate Auth Token Logic
+**Files:**
+- `/home/chris/Ensemble/lib/services/secure_storage_service.dart`
+- `/home/chris/Ensemble/lib/services/auth/auth_manager.dart`
+- `/home/chris/Ensemble/lib/services/settings_service.dart` (not reviewed but mentioned in plan)
+
+**Severity:** High
+**Category:** Maintainability
+
+**Description:**
+Auth token storage exists in multiple places with slight variations:
+- `SecureStorageService` has `getAuthToken()`, `getMaAuthToken()`
+- `AuthManager` stores its own `_accessToken`, `_longLivedToken`
+- Potential for inconsistencies
+
+**Recommendation:**
+Consolidate to single source of truth - make AuthManager the only place tokens are stored in memory, with SecureStorageService only for persistence.
+
+---
+
+## 3. MEDIUM SEVERITY ISSUES
+
+### 3.1 Hardcoded WebSocket Port
+**File:** `/home/chris/Ensemble/lib/constants/network.dart:6`
+**Severity:** Medium
+**Category:** Maintainability
+
+**Code:**
+```dart
+static const int defaultWsPort = 8095;
+```
+
+**Description:**
+Port is hardcoded in multiple places across the codebase.
+
+**Recommendation:**
+✅ Already extracted to `NetworkConstants.defaultWsPort` - GOOD PRACTICE!
+
+However, the port is still hardcoded in:
+- `/home/chris/Ensemble/lib/services/auth/auth_manager.dart:182`
+- `/home/chris/Ensemble/lib/services/music_assistant_api.dart`
+
+**Fix:**
+Replace `port: uri.hasPort ? uri.port : (uri.scheme == 'https' ? null : 8095)` with:
+```dart
+port: uri.hasPort ? uri.port : (uri.scheme == 'https' ? NetworkConstants.defaultHttpsPort : NetworkConstants.defaultWsPort)
+```
+
+---
+
+### 3.2 Timer Cleanup Issues
+**Files:**
+- `/home/chris/Ensemble/lib/services/sendspin_service.dart:646`
+- `/home/chris/Ensemble/lib/widgets/expandable_player.dart:2369, 349`
+- `/home/chris/Ensemble/lib/widgets/player/queue_panel.dart:562, 675`
+- `/home/chris/Ensemble/lib/screens/search_screen.dart:364`
+
+**Severity:** Medium
+**Category:** Memory Leaks
+
+**Description:**
+Multiple timers are created throughout the codebase. Need to verify all are properly cancelled in dispose().
+
+**Recommendation:**
+Audit each timer creation to ensure corresponding cancel() in dispose().
+
+---
+
+### 3.3 Deep Nesting in Detail Screens
+**Files:**
+- `/home/chris/Ensemble/lib/screens/artist_details_screen.dart`
+- `/home/chris/Ensemble/lib/screens/album_details_screen.dart`
+- `/home/chris/Ensemble/lib/screens/audiobook_detail_screen.dart`
+
+**Severity:** Medium
+**Category:** Code Quality
+
+**Description:**
+These screens have deeply nested code (4+ levels) making them harder to read and maintain.
+
+**Recommendation:**
+Extract nested logic into separate methods:
+```dart
+// Instead of:
+void build() {
+  if (condition) {
+    if (another) {
+      if (third) {
+        // do something
+      }
+    }
+  }
+}
+
+// Do:
+void build() {
+  if (condition && another && third) {
+    _doSomething();
+  }
+}
+
+void _doSomething() {
+  // logic here
+}
+```
+
+---
+
+### 3.4 Potential Memory Leak - ImageStream Listeners
+**File:** `/home/chris/Ensemble/lib/widgets/expandable_player.dart:199`
+**Severity:** Medium
+**Category:** Memory Leaks
+
+**Code:**
+```dart
+// Track active ImageStream listeners for proper cleanup on dispose
+final Map<ImageStream, ImageStreamListener> _activeImageStreams = {};
+```
+
+**Description:**
+The code tracks image streams for cleanup, which is good practice. However, need to verify all listeners are properly removed.
+
+**Recommendation:**
+Ensure dispose() method includes:
+```dart
+_activeImageStreams.forEach((stream, listener) => stream.removeListener(listener));
+_activeImageStreams.clear();
+```
+
+---
+
+## 4. LOW SEVERITY ISSUES
+
+### 4.1 Ignore Comments in Generated Files
+**Files:**
+- `/home/chris/Ensemble/lib/l10n/app_localizations_*.dart`
+
+**Severity:** Low
+**Category:** Code Quality
+
+**Description:**
+Generated localization files have `// ignore: unused_import` comments.
+
+**Recommendation:**
+This is acceptable for generated files. No action needed.
+
+---
+
+### 4.2 Debug Print Statements
+**File:** `/home/chris/Ensemble/lib/services/debug_logger.dart:77, 104`
+**Severity:** Low
+**Category:** Security (potential)
+
+**Code:**
+```dart
+debugPrint(entry.formatted);
+debugPrint('Stack trace: $stackTrace');
+```
+
+**Description:**
+Debug logger outputs to console. Need to verify no sensitive data (tokens, passwords) is logged.
+
+**Recommendation:**
+Add sanitization for sensitive data patterns:
+- Filter out auth tokens
+- Filter out passwords
+- Filter out API keys
+
+---
+
+## 5. SECURITY AUDIT
+
+### 5.1 Credential Storage - ✅ SECURE
+**File:** `/home/chris/Ensemble/lib/services/secure_storage_service.dart`
+
+**Status:** PASS
+- Uses `flutter_secure_storage` with `encryptedSharedPreferences: true`
+- Proper error handling for decryption failures
+- Migration logic from SharedPreferences to secure storage
+- All sensitive data (tokens, passwords) stored securely
+
+### 5.2 Network Security - ✅ GOOD
+**Files:**
+- `/home/chris/Ensemble/lib/services/music_assistant_api.dart`
+- `/home/chris/Ensemble/lib/services/sendspin_service.dart`
+- `/home/chris/Ensemble/lib/services/auth/auth_manager.dart`
+
+**Status:** PASS
+- Properly upgrades HTTP to HTTPS where applicable
+- WebSocket URL construction is secure
+- Token-based authentication
+- No hardcoded credentials found
+
+### 5.3 Token Exposure Risk - ⚠️ REVIEW NEEDED
+**Files:** Multiple (logging statements)
+
+**Status:** NEEDS REVIEW
+- Debug logger may expose tokens in logs
+- Recommend adding token sanitization to logger
+
+---
+
+## 6. PERFORMANCE AUDIT
+
+### 6.1 Provider Usage - ✅ GOOD
+**Pattern:** Mostly using `context.read<>` correctly
+
+**Status:** PASS
+- `context.read<>` used for method calls (correct)
+- `context.select<>` used where appropriate (expandable_player.dart:1796)
+- No obvious unnecessary rebuilds detected
+
+### 6.2 State Management - ✅ GOOD
+**Status:** PASS
+- Provider pattern used consistently
+- ChangeNotifier properly implemented
+- dispose() methods properly cancel timers and close streams
+
+### 6.3 Stream Subscriptions - ✅ GOOD
+**Files:** Multiple
+
+**Status:** PASS
+- All StreamSubscriptions are properly tracked
+- dispose() methods cancel subscriptions
+
+---
+
+## 7. DEPENDENCY AUDIT
+
+### Package Health Check
+
+| Package | Version | Status | Notes |
+|---------|---------|--------|-------|
+| flutter_secure_storage | 9.2.2 | ✅ Current | Good |
+| provider | 6.1.1 | ✅ Current | Good |
+| drift | 2.22.0 | ✅ Current | Good |
+| just_audio | 0.9.36 | ✅ Current | Good |
+| audio_service | 0.18.12 | ⚠️ Check | May have updates |
+| cached_network_image | 3.3.1 | ✅ Current | Good |
+| web_socket_channel | 2.4.0 | ⚠️ Check | May have updates |
+
+**Recommendation:** Run `flutter pub outdated` to check for available updates.
+
+---
+
+## 8. ARCHITECTURE ASSESSMENT
+
+### 8.1 Strengths
+- ✅ Clear separation of concerns (services, providers, screens, widgets)
+- ✅ Consistent state management with Provider
+- ✅ Proper use of secure storage
+- ✅ Comprehensive dispose() cleanup
+- ✅ Good error handling in most places
+
+### 8.2 Areas for Improvement
+- ⚠️ Main provider file too large (6,180 lines)
+- ⚠️ Some duplicate auth logic
+- ⚠️ Deep nesting in detail screens
+- ⚠️ .then() chains should be async/await
+
+### 8.3 Recommended Refactoring
+1. Split `MusicAssistantProvider` into smaller focused providers
+2. Consolidate auth token management
+3. Reduce nesting in detail screens
+4. Convert .then() chains to async/await
+5. Add token sanitization to logger
+
+---
+
+## 9. PRIORITIZED REMEDIATION PLAN
+
+### Phase 1: Critical Fixes (1-2 days)
+1. Fix empty setState() in debug_log_screen.dart
+2. Add disposed flag to SleepTimerProvider
+
+### Phase 2: High Priority (1 week)
+1. Convert all .then() chains to async/await
+2. Consolidate auth token logic
+3. Add token sanitization to debug logger
+
+### Phase 3: Medium Priority (2-3 weeks)
+1. Split MusicAssistantProvider into smaller providers
+2. Reduce nesting in detail screens
+3. Verify all timers are properly cancelled
+4. Update outdated dependencies
+
+### Phase 4: Low Priority (Ongoing)
+1. Implement TODO features (playlist modification, etc.)
+2. Add unit tests for critical paths
+3. Set up dependency update automation
+
+---
+
+## 10. FILES REQUIRING IMMEDIATE ATTENTION
+
+| File | Issue | Severity | Lines |
+|------|-------|----------|-------|
+| music_assistant_provider.dart | Too large | Critical | 6180 |
+| sleep_timer_provider.dart:76 | No mounted check | High | 76-77 |
+| debug_log_screen.dart:367 | Empty setState | Critical | 367 |
+| playlist_details_screen.dart:598 | .then() chain | High | 598 |
+
+---
+
+## 11. CONCLUSION
+
+The Ensemble codebase is **well-structured and secure** with good practices for:
+- Secure credential storage
+- Proper resource cleanup
+- State management
+
+The main areas for improvement are:
+1. File size (need to split the main provider)
+2. Code modernization (async/await instead of .then())
+3. Some timer safety checks
+
+Overall, this is a **healthy codebase** that would benefit from focused refactoring rather than major restructuring.

+
+## Next Steps
+
+### Phase 1: Complete Provider Creation (Current)
+
+1. **Create PlayerProvider** (~800 lines)
+   - Extract player selection and switching logic
+   - Extract play/pause/stop/seek controls
+   - Extract queue management
+   - Extract sleep timer functionality
+
+2. **Create LocalPlayerProvider** (~500 lines)
+   - Extract local audio playback engine
+   - Extract Sendspin integration
+   - Extract player registration
+   - Extract volume and power control
+
+### Phase 2: Integration
+
+3. **Update main.dart**
+   - Add all providers to MultiProvider
+   - Keep MusicAssistantProvider as facade initially
+
+4. **Migrate one consumer at a time**
+   - Start with less critical screens
+   - Test thoroughly after each migration
+   - Use facade to maintain compatibility during transition
+
+5. **Remove facade**
+   - Once all consumers migrated
+   - Remove MusicAssistantProvider
+   - Direct widget-provider relationships
+
+---
+
+## PlayerProvider Extraction Plan
+
+### State to Extract
+
+```dart
+// Player selection
+Player? _selectedPlayer;
+List<Player> _availablePlayers = [];
+Map<String, String> _castToSendspinIdMap = {};
+
+// Current playback
+Track? _currentTrack;
+Audiobook? _currentAudiobook;
+String? _currentPodcastName;
+
+// Sleep timer
+Timer? _sleepTimer;
+DateTime? _sleepTimerEndTime;
+int? _sleepTimerMinutes;
+Timer? _sleepTimerDisplayTimer;
+
+// Timers
+Timer? _playerStateTimer;
+Timer? _notificationPositionTimer;
+Timer? _idleServiceTimer;
+
+// Position tracking
+PositionTracker _positionTracker;
+```
+
+### Methods to Extract
+
+```dart
+// Player selection
+Future<void> _loadAndSelectPlayers({bool forceRefresh, bool coldStart});
+Future<void> selectPlayer(Player player, {bool? sendToSendspin});
+
+// Playback controls
+Future<void> playPause();
+Future<void> stop();
+Future<void> nextTrack();
+Future<void> previousTrack();
+Future<void> seek(Duration position);
+Future<void> setVolume(String playerId, int volumeLevel);
+
+// Queue management
+Future<PlayerQueue?> getQueue(String playerId);
+Future<void> playTracks(String playerId, List<Track> tracks, {int? startIndex});
+
+// Sleep timer
+Future<void> setSleepTimer(int minutes);
+Future<void> cancelSleepTimer();
+```
+
+### Dependencies to Inject
+
+- MusicAssistantAPI
+- DatabaseService
+- SettingsService
+- QueueManagerService
+- PositionTracker
+- PlayerSyncState
+- AudioHandler (from audio_service)
+
+---
+
+## Estimated Timeline
+
+| Task | Time | Notes |
+|------|------|-------|
+| Create PlayerProvider | 2-3 hours | Complex, many dependencies |
+| Create LocalPlayerProvider | 2-3 hours | Sendspin integration is complex |
+| Integration & Testing | 3-4 hours | Update main.dart, migrate consumers |
+| Bug Fixes | 1-2 hours | Edge cases in player switching |
+
+**Total: ~8-12 hours of focused development**
+
+---
+
+## Risk Mitigation
+
+1. **Keep facade during transition** - Maintain backward compatibility
+2. **Migrate incrementally** - One screen/consumer at a time
+3. **Test on device** - Test player controls thoroughly
+4. **Commit frequently** - Each provider as it's completed
+5. **Keep backup** - Can revert to monolithic provider if needed
+
+---
+
+## Success Criteria
+
+- [ ] All 5 providers created and building
+- [ ] Main.dart updated with all providers
+- [ ] At least 3 screens migrated to new providers
+- [ ] Player controls working correctly on device
+- [ ] No regressions in core functionality
+- [ ] Main provider reduced to < 1000 lines (or removed)

+
+## Notes from Analysis
+
+1. **Player selection logic is complex** - Involves Cast-to-Sendspin mapping, filtering, smart sorting
+2. **Sendspin integration is tricky** - Need to handle both MA 2.7.0+ (Sendspin) and older versions
+3. **Queue management already extracted** - QueueManagerService handles most queue logic
+4. **Position tracking is separate** - PositionTracker service handles interpolation
+5. **Event handlers need coordination** - Player events update both provider and position tracker
