Developer Overview

Architecture: The app follows a clean, modular architecture using Riverpod providers for state management and Firebase as the data source. The codebase is organized into layers: UI (screens and widgets), providers (business logic), repositories (data access), and services (external integrations). This separation ensures testability, maintainability, and scalability.

Initialization: AppManager handles the initialization of core services including Firebase, Stripe, Google Mobile Ads, SharedPreferences, and notification services. It also sets up Crashlytics and Analytics for monitoring, ensuring everything is ready before the app starts.

Routing: GoRouter manages all navigation including deep links, onboarding flow, authentication state, and session routing. The router determines the initial screen based on user state (loading, onboarding, logged in/out) and handles complex navigation scenarios.

Cloud Functions: Server-side Firebase Cloud Functions handle critical backend operations including payment intent creation, order confirmations, email notifications, admin notifications, product statistics updates, and various Firestore triggers for real-time data synchronization.

Data Flow: UI → Providers → Repositories → Data Sources (Firebase Firestore, Firebase Storage, Cloud Functions). This unidirectional data flow pattern makes debugging easier and ensures predictable app behavior.
