From 6d1cf5fac3218ba600237ba5e42cf4743b2b6a15 Mon Sep 17 00:00:00 2001 From: Mikkeli Matlock Date: Sun, 31 Aug 2025 01:15:00 +0900 Subject: [PATCH] feat: implement GpsDataManager architecture with modular design MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Add GpsDataManager singleton service for centralized GPS data processing - Refactor main app to use processed GPS data streams instead of raw position data - Add haptic feedback to all main UI tap interactions (theme, unit, navigation) - Implement faster GPS update frequency (500ms timeLimit in LocationSettings) - Clean up verbose debug logging while preserving essential error logs - Remove unused debug variables and imports - Preserve existing background survival mechanisms and overlay lifecycle - Add temporary GPS simulation while resolving geolocator engine conflicts Architecture improvements: - Clean data flow: GPS Hardware โ†’ GpsDataManager โ†’ Main App โ†’ Overlay - Single source of truth for processed GPS data in manager - Separation of concerns: GPS logic isolated from UI components - Foundation ready for intelligent caching logic implementation Technical notes: - GPS engine conflict detected, temporarily using simulation data - All functionality tested and working with test data - Real GPS integration pending engine conflict resolution ๐Ÿค– Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- lib/gps_service.dart | 1 + lib/main.dart | 285 +++++++++-------------------- lib/services/gps_data_manager.dart | 210 +++++++++++++++++++++ 3 files changed, 298 insertions(+), 198 deletions(-) create mode 100644 lib/services/gps_data_manager.dart diff --git a/lib/gps_service.dart b/lib/gps_service.dart index 8e6d644..362f614 100644 --- a/lib/gps_service.dart +++ b/lib/gps_service.dart @@ -10,6 +10,7 @@ class GpsService { locationSettings: const LocationSettings( accuracy: LocationAccuracy.bestForNavigation, distanceFilter: 0, + timeLimit: Duration(milliseconds: 500), // Force updates every 500ms for faster GPS refresh ), );
