A secure and modern mobile banking application built with Flutter, following best practices and clean architecture principles.

📱 App Architecture

1. Clean Architecture

The app follows Clean Architecture principles with the following layers:

lib/ ├── core/ # Core functionality and utilities ├── data/ # Data layer (repositories, data sources) ├── domain/ # Business logic and entities ├── presentation/ # UI layer (screens, widgets) └── main.dart

🔧 Layer Details

• Core: 🛠️ Contains common utilities, constants, and shared components
• Data: 💾 Handles data operations and external services
• Domain: 🏢 Contains business logic and use cases
• Presentation: 🎨 Manages UI components and state management

2. ⭐ Key Features

• 🔐 Secure authentication (Biometric, 2FA)
• 👤 Account management
• 📊 Transaction history
• 💸 Fund transfers
• 💳 Bill payments
• 📄 Account statements
• 🔔 Push notifications
• ⚙️ Profile management

3. 🔄 State Management

• 🧩 BLoC (Business Logic Component) pattern for state management
• 🔀 Clear separation of UI and business logic
• ⚡ Predictable state transitions

🔒 Security Best Practices

1. 🔑 Authentication & Authorization
