Phase 1 Plan 04: Auth Repository and State Management Summary

Supabase authentication repository with Riverpod global state management, implementing complete auth interface with automatic UI updates

Performance

• Duration: 8 min
• Started: 2026-01-28T15:33:07Z
• Completed: 2026-01-28T15:40:45Z
• Tasks: 2
• Files modified: 2

Accomplishments

• Complete AuthRepository implementation using Supabase authentication methods
• Global authentication state management with Riverpod StateNotifier
• Automatic UI updates through auth state change streams
• Comprehensive error handling with custom exception mapping
• Loading state management for all authentication operations

Task Commits

Each task was committed atomically:

1. Task 1: Implement AuthRepository with Supabase - 294d537 (feat)
2. Task 2: Create AuthProvider for state management - f3397a9 (feat)

Plan metadata: (will be committed with summary)

Files Created/Modified

• lib/features/authentication/data/repositories/auth_repository_impl.dart - Complete Supabase auth implementation with all interface methods
• lib/providers/auth_provider.dart - Riverpod state management with AuthState class and convenience providers

Decisions Made

• Used Riverpod StateNotifier for authentication state management (consistent with project dependencies)
• Implemented comprehensive AuthRepository interface covering all authentication use cases
• Created AuthState class to encapsulate user, loading, and error states
• Added convenience providers for common UI state access patterns (currentUser, isAuthenticated, isLoading, error)

Deviations from Plan

None - plan executed exactly as written.

Issues Encountered

None - implementation proceeded smoothly without issues.

User Setup Required

None - no external service configuration required for this plan.

Next Phase Readiness

Authentication foundation is now complete with:

• AuthRepository implementation ready for Supabase integration
• Global state management that automatically responds to auth changes
• Error handling and loading states properly implemented
• Session persistence will be handled by Supabase automatically

Ready for next phase: 01-05-router-integration (navigation and auth guards).
