# Architecture Documentation

This section contains comprehensive technical architecture documentation for the Remind Tools monorepo.

## Architecture Overview

Remind Tools follows a **Clean Architecture + Domain-Driven Design (DDD)** approach, ensuring:

* Separation of concerns
* Testability and maintainability
* Scalability across multiple platforms
* Code reusability through shared packages

## Technology Stack

### Frontend

* **Flutter**: Cross-platform framework (iOS, Android, Web, Desktop)
* **State Management**: BLoC + Riverpod hybrid approach
* **UI Components**: Material Design 3 with custom theming

### Backend

* **Supabase**: PostgreSQL database with real-time capabilities
* **Authentication**: Supabase Auth with social providers
* **Edge Functions**: Serverless compute for business logic

### Integrations

* **AI**: Google Gemini Pro for intelligent features
* **Maps**: MapBox GL for 3D mapping and navigation
* **Analytics**: Custom event tracking and monitoring

## Architectural Principles

1. **Clean Architecture Layers**
   * Presentation Layer (UI/Controllers)
   * Domain Layer (Business Logic/Entities)
   * Data Layer (Repositories/Data Sources)

2. **Domain-Driven Design**
   * Bounded contexts for each application
   * Rich domain models
   * Ubiquitous language

3. **SOLID Principles**
   * Single Responsibility
   * Open/Closed
   * Liskov Substitution
   * Interface Segregation
   * Dependency Inversion

## Performance Considerations

* Lazy loading and code splitting
* Optimized asset management
* Efficient state management
* Database query optimization
* Caching strategies
