This commit adds a comprehensive caching system that loads all data
on app launch and keeps it in memory, eliminating redundant API calls
when navigating between screens.
Core Implementation:
- DataCache: Singleton holding all app data in StateFlow
- DataPrefetchManager: Loads all data in parallel on app launch
- Automatic cache updates on create/update/delete operations
Features:
- ✅ Instant screen loads from cached data
- ✅ Reduced API calls (no redundant requests)
- ✅ Better UX (no loading spinners on navigation)
- ✅ Offline support (data remains available)
- ✅ Consistent state across all screens
Cache Contents:
- Residences (all + my residences + summaries)
- Tasks (all tasks + tasks by residence)
- Documents (all + by residence)
- Contractors (all)
- Lookup data (categories, priorities, frequencies, statuses)
ViewModels Updated:
- ResidenceViewModel: Uses cache with forceRefresh option
- TaskViewModel: Uses cache with forceRefresh option
- Updates cache on successful create/update/delete
iOS Integration:
- Data prefetch on successful login
- Cache cleared on logout
- Background prefetch doesn't block authentication
Usage:
// Load from cache (instant)
viewModel.loadResidences()
// Force refresh from API
viewModel.loadResidences(forceRefresh: true)
Next Steps:
- Update DocumentViewModel and ContractorViewModel (same pattern)
- Add Android MainActivity integration
- Add pull-to-refresh support
