- Add OverlayError enum (permission, creationFailed, communicationDegraded)
- Add OverlayService dependency via constructor injection
- Add onError callback field for error surfacing (set by SpeedometerScreen)
- Refactor showOverlay to check permission before showing overlay
- Refactor showOverlay to verify overlay creation via isActive check
- Only set _isOverlayActive after verification succeeds
- Replace all FlutterOverlayWindow calls with OverlayService methods
- Add GPS grace period timer (30s) in _handleOverlayClose
- Cancel grace period if overlay reopens within 30s
- Register OverlayService in MultiProvider before OverlayProvider
- Inject OverlayService into OverlayProvider constructor

- Created lib/providers/overlay_provider.dart
- Extends ChangeNotifier for reactive overlay state management
- Centralizes ALL overlay operations: show, close, toggle, status monitoring, messaging
- updateDependencies() called by ProxyProvider when GPS or Settings change
- Subscribes to GpsDataManager.dataStream on first update (persist subscription)
- Skips overlay sends when inactive (if-check, not unsubscribe)
- _isDisposed guards on all async-accessible methods
- showOverlay() sends initial data with overlay size info
- _pushDataToOverlay() sends GPS data with current theme/unit
- _startListeningToOverlayMessages() handles overlay→main IPC
- _startOverlayStatusCheck() polls overlay status at 1s interval
- _handleOverlayClose() manages cleanup and optional bring-to-front
- pushCurrentData() public method for background heartbeat usage
- dispose() cancels 4 subscriptions/timers, calls super.dispose() last
- Created lib/providers/settings_provider.dart
- Extends ChangeNotifier for reactive state management
- Constructor accepts pre-initialized SharedPreferences instance
- Loads theme index and speed unit synchronously from SharedPreferences
- cycleTheme() and cycleUnit() methods with haptic feedback
- Persists settings to SharedPreferences on every change
- Both cycle methods call notifyListeners() for reactive UI updates
- No notifyListeners() in constructor (runs before first build)
Features added:
- Auto-rotate support for portrait/landscape orientations
- Interactive gauge: tap to switch between digital and analog modes
- Extended speed units: added knots with quick selector buttons
- New SpeedUnitSelector widget for convenient unit switching
Known issues identified:
- 10 package dependencies need updates to latest compatible versions
- Orientation switching needs to override system auto-rotate toggle
- Background color customization moved back to TODO (build issues)
