Navigation Interaction Conflict Prevention +**Problem**: When navigation sheet is open (route planning or route overview) and user taps a node to view tags, competing UI states create conflicts and inconsistent behavior. + +**Root Cause**: Two interaction modes trying to operate simultaneously: +- **Route planning/overview** (temporary selection states) +- **Node examination** (inspect/edit individual devices) + +**Solution**: **Prevention over management** - disable conflicting interactions entirely: +- Nodes and suspected locations are **dimmed and non-clickable** during `isInSearchMode` or `showingOverview` +- Visual feedback (0.5 opacity) indicates interactive elements are temporarily disabled +- Clean UX: users must complete/cancel navigation before examining nodes + +**Brutalist Approach**: Prevent the conflict from ever happening rather than managing complex state transitions. Single condition check disables taps and applies dimming consistently across all interactive map elements. + +### 2. Node Edge Blinking Bug +**Problem**: Nodes appear/disappear exactly when their centers cross screen edges, causing "blinking" effect as they pop in/out of existence at screen periphery. + +**Root Cause**: Node rendering uses exact `camera.visibleBounds` while data prefetching expands bounds by 3x. This creates a mismatch where data exists but isn't rendered until nodes cross the exact screen boundary. + +**Solution**: Expanded rendering bounds by 1.3x while keeping data prefetch at 3x: +- Added `kNodeRenderingBoundsExpansion = 1.3` constant in `dev_config.dart` +- Added `_expandBounds()` method to `MapDataManager` (reusing proven logic from prefetch service) +- Modified `getNodesForRendering()` to use expanded bounds for rendering decisions +- Nodes now appear before sliding into view and stay visible until after sliding out + +**Brutalist Approach**: Simple bounds expansion using proven mathematical logic. No complex visibility detection or animation state tracking. + +### 3. Route Overview Follow-Me Management +**Problem**: Route overview didn't disable follow-me mode, causing unexpected map jumps. Route resume didn't intelligently handle follow-me based on user proximity to route. + +**Root Cause**: No coordination between route overview display and follow-me mode. Resume logic didn't consider user location relative to route path. + +**Solution**: Smart follow-me management for route overview workflow: +- **Opening overview**: Store current follow-me mode and disable it to prevent map jumps +- **Resume from overview**: Check if user is within configurable distance (500m) of route path +- **Near route**: Center on GPS location and restore previous follow-me mode +- **Far from route**: Center on route start without follow-me +- **Zoom level**: Use level 16 for resume instead of 14 + +**Brutalist Approach**: Simple distance-to-route calculation with clear decision logic. No complex state machine - just store/restore with proximity-based decisions. + +## Files Modified + +### Core Logic Changes +- `lib/widgets/map/map_data_manager.dart` - Added bounds expansion for node rendering +- `lib/dev_config.dart` - Added rendering bounds expansion constant + +### Navigation Interaction Prevention +- `lib/widgets/map/marker_layer_builder.dart` - Added dimming and tap disabling for conflicting navigation states +- `lib/widgets/map/node_markers.dart` - Added `enabled` parameter to prevent tap handler fallbacks +- `lib/widgets/map/suspected_location_markers.dart` - Added `enabled` and `shouldDimAll` parameters for consistent behavior +- Removed navigation state cleanup code (prevention approach eliminates need) + +### Route Overview Follow-Me Management +- `lib/screens/coordinators/navigation_coordinator.dart` - Added follow-me tracking and smart resume logic +- `lib/dev_config.dart` - Added route proximity threshold and resume zoom level constants + +### Version & Documentation +- `pubspec.yaml` - Updated to v1.6.2+28 +- `assets/changelog.json` - Added v1.6.2 changelog entry +- `V1.6.2_CHANGES_SUMMARY.md` - This documentation + +## Technical Implementation Details + +### Navigation Interaction Prevention Pattern +```dart +// Disable node interactions when navigation is in conflicting state +final shouldDisableNodeTaps = appState.isInSearchMode || appState.showingOverview; + +// Apply to all interactive elements +onNodeTap: shouldDisableNodeTaps ? null : onNodeTap, +onLocationTap: shouldDisableNodeTaps ? null : onSuspectedLocationTap, +shouldDim: shouldDisableNodeTaps, // Visual feedback via dimming +``` + +This pattern prevents conflicts by making competing interactions impossible rather than trying to resolve them after they occur. + +### Bounds Expansion Implementation +```dart +/// Expand bounds by the given multiplier, maintaining center point. +/// Used to expand rendering bounds to prevent nodes blinking at screen edges. +LatLngBounds _expandBounds(LatLngBounds bounds, double multiplier) { + final centerLat = (bounds.north + bounds.south) / 2; + final centerLng = (bounds.east + bounds.west) / 2; + + final latSpan = (bounds.north - bounds.south) * multiplier / 2; + final lngSpan = (bounds.east - bounds.west) * multiplier / 2; + + return LatLngBounds( + LatLng(centerLat - latSpan, centerLng - lngSpan), + LatLng(centerLat + latSpan, centerLng + lngSpan), + ); +} +``` + +The expansion maintains the center point while scaling the bounds uniformly.
