What types of architectural solutions do you apply in your developments?

In Flutter development, the following architectural solutions are often used:

• BLoC (Business Logic Component) — separates business logic and UI, using streams to manage state.
• Provider — a simple and popular way to manage state through dependency injection.
• MVVM (Model-View-ViewModel) — separates presentation from logic, with ViewModel containing state and logic.
• Redux — a centralized state store with predictable changes through actions and reducers.

The choice depends on the complexity of the project and team preferences. For example, for small applications, Provider is often sufficient, while for larger ones, BLoC or Redux are preferred.

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('Count: \\${counter.count}'),
)
