How do you structure the architecture of components in an application considering scalability and support?

To ensure scalability and maintainability, the architecture of components in Flutter is usually built considering the following principles:

• Separation of concerns: each widget or component is responsible for its part of the UI or logic.
• Use of state management patterns: such as Provider, BLoC, Riverpod, to separate business logic from UI.
• Modularity: components should be reusable and independent.
• Clean architecture: separation into layers (presentation, business logic, data) facilitates maintenance and testing.

Example structure:

/lib
  /models      # data models
  /services    # working with API, database
  /blocs       # business logic and state management
  /widgets     # reusable UI components
  /screens     # application screens

This approach makes it easy to add new features, change implementation without affecting other parts of the application, and simplifies testing.
