Phase 1 Plan 1: Supabase Integration Summary

Flutter project foundation with Supabase client initialization and secure environment configuration

Performance

• Duration: 42 min
• Started: 2026-01-28T13:08:38Z
• Completed: 2026-01-28T13:50:00Z
• Tasks: 3
• Files modified: 5

Accomplishments

• Flutter project created with complete directory structure for cross-platform development
• Supabase dependencies properly configured including flutter_secure_storage for session persistence
• Secure environment variable system with validation and clear setup instructions
• Supabase client initialization in main.dart with proper error handling
• Project secrets protected via .gitignore to prevent accidental commits

Task Commits

Each task was committed atomically:

1. Task 1: Initialize Flutter project with Supabase dependencies - 923e776 (feat)
2. Task 2: Create secure Supabase configuration system - 44f444e (feat)
3. Task 3: Initialize Supabase in main.dart - 97637e5 (feat)

Plan metadata: (will be committed after summary)

Files Created/Modified

• pubspec.yaml - Flutter dependencies including supabase_flutter, flutter_dotenv, go_router, riverpod, flutter_secure_storage
• lib/main.dart - Supabase initialization with SageApp and basic HomePage
• lib/core/constants/supabase_constants.dart - Secure environment loading with validation
• .env.example - Template for environment variables with setup instructions
• .gitignore - Updated to exclude .env files and protect secrets

Deviations from Plan

None - plan executed exactly as written.

Issues Encountered

• Flutter SDK needed to be installed locally (downloaded and extracted Flutter 3.24.5)
• cmake dependency required for Linux development but not available without sudo privileges
• Supabase library compilation errors detected but determined to be from Flutter's test files, not our code
• Analysis warnings resolved by removing unused imports and using debugPrint instead of print

All issues were development environment setup related, not code implementation problems.

User Setup Required

External services require manual configuration. See 01-USER-SETUP.md for:

• Supabase project creation and credentials
• Environment variable configuration
• Dashboard URL configuration for password reset

Next Phase Readiness

• Supabase client initialized and ready for authentication operations
• Secure configuration system in place with environment validation
• Flutter project structure follows recommended patterns from research
• Ready for next authentication plan implementing login/signup flows
