Yes, in Flutter projects I have used the Scoped Model pattern for state management. Scoped Model allows organizing the application's state into models that are accessible to child widgets via context.

Key points:

  • The model inherits from Model and contains data and methods to modify it.
  • Widgets subscribe to model changes through ScopedModelDescendant, which allows automatic UI updates when the state changes.

Example:

class CounterModel extends Model {
  int _count = 0;

  int get count => _count;

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

// In widget
ScopedModel<CounterModel>(
  model: CounterModel(),
  child: ScopedModelDescendant<CounterModel>(
    builder: (context, child, model) => Text('Count: \\${model.count}'),
  ),
)

This approach is simple and suitable for small to medium applications, but for more complex projects, more powerful solutions like Provider or Bloc are often used.
