Architecture Patterns

Clean Architecture - Separation of concerns with clear boundaries
Repository Pattern - Abstraction layer for data access
Provider Pattern - State management with Riverpod
Service Layer - Business logic abstraction
MVVM - Model-View-ViewModel pattern for UI

🎨 Design System

Design Tokens

Colors - Primary, secondary, semantic colors with light/dark variants
Typography - Inter font family with consistent text styles
Spacing - 8px grid system for consistent spacing
Breakpoints - Mobile (≤450px), Tablet (451-800px), Desktop (≥801px)

Components

AppButton - Consistent button styling with variants
AppInput - Form inputs with validation and accessibility
ThemeToggleButton - System/light/dark theme switcher
MainLayout - Responsive navigation shell

Responsive Design

Mobile - Bottom navigation with hamburger menu
Tablet - Navigation rail with compact layout
Desktop - Persistent sidebar navigation with full features

🔐 Authentication

Mock Authentication Service

The app includes a mock authentication service for development and testing:

Demo Credentials:

Email: demo@vtrader.in
Password: password123

Service Abstraction

The authentication system is designed with abstraction in mind:

AuthService - Abstract base class
MockAuthService - Development implementation
Easy to swap with Firebase Auth, REST API, or other providers

Features

Sign up with email/password
Sign in with session persistence
Password reset flow
Profile management
Secure session storage

💾 Data Management

Local Storage

Hive - Primary local database for offline-first architecture
SharedPreferences - User preferences and settings
Secure Storage - Authentication tokens and sensitive data

Data Models

UserModel - User profile and preferences
TradeModel - Trading transactions with P&L calculations
BrokerModel - Broker connections and sync settings
StrategyModel - Trading strategies with risk management
PositionModel - Current market positions

Data Flow

UI Layer - Widgets and pages
State Layer - Riverpod providers and notifiers
Service Layer - Business logic and validation
Repository Layer - Data access abstraction
Storage Layer - Local database and preferences

🔄 State Management

Riverpod Architecture

Providers - Dependency injection and state management
StateNotifiers - Complex state management with immutable updates
FutureProviders - Async data loading with error handling
StreamProviders - Real-time data updates

Key Providers

themeModeProvider - Theme state management
routerProvider - Navigation configuration
authStateProvider - Authentication state
tradesProvider - Trade data management

📱 Platform Support

Web

Responsive design for desktop and mobile browsers
PWA capabilities (future enhancement)
URL-based routing with deep linking

Android

Material Design 3 components
Adaptive layouts for phones and tablets
Android-specific optimizations

iOS

Cupertino design elements where appropriate
iOS-specific navigation patterns
Safe area handling
