What architectural approaches are known in Flutter?

The following architectural approaches are known:

• BLoC (Business Logic Component): Based on data streams. Separates logic (BLoC) and UI. Reactive approach, suitable for complex applications.
• Provider: The simplest and recommended Google approach for state management. Uses InheritedWidget. Flexible and suitable for most cases.
• Riverpod: An improved version of Provider. Solves some of its problems (runtime errors, boilerplate), more typed.
• GetX: Lightweight and powerful framework. Offers state management, dependency injection, navigation, and more. Often criticized for excess and "magic".
• MobX: Uses Observable for state management. Suitable for complex reactive scenarios.
• MVC (Model-View-Controller): Classic pattern. Not native to Flutter. Requires adaptation.
• MVVM (Model-View-ViewModel): Also a classic pattern. ViewModel acts as an intermediary between View and Model.

Chosen depending on the complexity of the project, team preferences, and the need for specific features (e.g., reactivity, simplicity, etc.).
