In Flutter, the following architectural patterns are often used:

BLoC (Business Logic Component) — separates business logic and UI, using Streams to manage state. It allows for easy testing and scaling of the application.
Provider — a simple and popular way to manage state using InheritedWidget, suitable for small and medium projects.
MVVM (Model-View-ViewModel) — separates UI (View), business logic (ViewModel), and data (Model). The ViewModel notifies the View of changes.
Redux — centralized state management through a single store and actions, useful for large applications with complex logic.

Example of using Provider for state management:

class Counter with ChangeNotifier {
  int _count = 0;
  int get count => _count;

  void increment() {
    _count++;
    notifyListeners();
  }
}

// In widget
Consumer<Counter>(
  builder: (context, counter, child) => Text('${counter.count}'),
)
