What tools or approaches to state management in applications are you familiar with?

In Flutter, various tools and approaches are used for state management in applications, including:

• setState — the basic way to update state within a StatefulWidget.
• InheritedWidget / InheritedModel — for passing data down the widget tree.
• Provider — a popular package for state management using the InheritedWidget pattern, convenient and simple.
• Bloc (Business Logic Component) — an architectural pattern using streams for separating logic and UI.
• Riverpod — a modern alternative to Provider with improved safety and flexibility.
• Redux — a state management pattern with a centralized store and immutable states.
• MobX — reactive state management with automatic change tracking.

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}'),
)
