T-009: Add Plant Feature

Overview

This PR implements a complete plant management system for the DemoFlutterCursor Flutter application, including a list of plants and a UI tool to add plants to the list, following Test-Driven Development (TDD) principles.

Implementation Details

Architecture

• Domain Layer: Plant model with Freezed, repository interface, and use cases (get, add, update)
• Data Layer: API, DAO, and repository implementation with local-first approach
• UI Layer: StateNotifier pattern with Freezed states, components, and widgets
• Testing: Comprehensive test coverage with fake implementations for all layers

Key Features

• ✅ Plant list display with empty state handling
• ✅ Add plant form with name, type, and optional description
• ✅ Plant data persistence through repository pattern
• ✅ Internationalization support using Slang
• ✅ State management using StateNotifier pattern
• ✅ Error handling and loading states

Files Created/Modified

• Task Definition: .status/tasks/T-009_add_plant.md
• Status Update: .status/status.md marked as "In Progress"
• Internationalization: Added plant strings to lib/i18n/strings.i18n.json
• Domain Layer: lib/modules/plants/domain/ (models, repositories, use cases)
• Data Layer: lib/modules/plants/data/ (API, DAO, repository implementation)
• UI Layer: lib/modules/plants/ (page, components, widgets, providers)
• Tests: test/modules/plants/ (comprehensive test coverage for all layers)

Test Results

• ✅ All tests passing: 60 total tests (including 13 plant module tests)
• ✅ Domain layer tests: Use cases with fake repository implementations
• ✅ Data layer tests: Repository with fake API and DAO implementations
• ✅ UI layer tests: StateNotifier with fake use case implementations
• ✅ Code generation: All Freezed files generated successfully
• ✅ Lint check: flutter analyze --no-fatal-infos --no-fatal-warnings passes

TDD Workflow Followed

1. ✅ Created task definition and updated project status
2. ✅ Added internationalization strings
3. ✅ Implemented domain layer with tests first (TDD)
4. ✅ Implemented data layer with tests first (TDD)
5. ✅ Implemented UI layer with tests first (TDD)
6. ✅ Generated code using build_runner
7. ✅ Verified all tests pass

Technical Implementation

• Models: Used sealed class with Freezed for immutable domain models
• State Management: StateNotifier with Freezed states for UI state management
• Repository Pattern: Local-first approach (check DAO, fallback to API)
• Dependency Injection: Riverpod providers for use case and repository injection
• Error Handling: Comprehensive error states and user feedback
• Code Style: Follows project conventions with package imports and naming patterns

Testing Notes

• All unit tests pass successfully
• Fake implementations used instead of mocking for better test reliability
• Test coverage includes success scenarios, error handling, and edge cases
• Local UI testing was attempted but blocked by Firebase web configuration issue (environment setup)

Verification Commands

# Lint check
flutter analyze --no-fatal-infos --no-fatal-warnings

# Run all tests
flutter test

# Run plant module tests specifically
flutter test test/modules/plants/

Notes

• Implementation follows established architectural patterns from example module
• All code generation completed successfully
• Firebase web configuration needed for local UI testing (environment setup issue)
• Plant feature is functionally complete and thoroughly tested
