What is your experience with implementing and using various state management systems in applications?

In my Flutter projects, I have used several state management systems, including Provider, Bloc, and Riverpod. For example, Provider is convenient for managing simple states such as toggles or counters due to its simplicity and integration with widgets. Bloc is suitable for more complex applications with a clear separation of business logic and UI, providing stream-based state management through events and states. Riverpod is appreciated for its flexibility and lack of dependency on context, which simplifies testing and scaling the application.

Example of using Provider:

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}'),
)
