The best architecture for Flutter using Clean Architecture is a combination of MVVM (Model-View-ViewModel) and GetX for state management. This structure ensures separation of concerns, making the app scalable, maintainable, and testable.

The architecture follows Uncle Bob's Clean Architecture Principles with layers:

1. Presentation Layer (UI & State Management)

• Contains: View (UI), Controller (ViewModel)
• Handles: User interactions, UI updates
• Uses: GetX for state management

2. Domain Layer (Business Logic)

• Contains: Entities, Abstract Repositories and Use Cases
• Handles: Business logic independent of frameworks

3. Data Layer (Repositories & Data Sources)

• Contains: Models, Repositories, Data Sources
• Handles: Data fetching from API, Database, Local Storage

✅ Separation of Concerns

✅ Easier Testing & Maintainability

✅ Reusability of Business Logic

✅ Scalable for Large Projects

✅ GetX for Simplified State Management
