MultipleAnswerController<T> class

A controller for managing ControlledMultipleAnswer selections programmatically.

This controller extends ValueNotifier<Iterable<T>?> to provide reactive state management for multiple selection components. It implements ComponentController to integrate with the controlled component system, allowing external control and listening to selection changes.

Example:

final controller = MultipleAnswerController<String>(['option1', 'option2']);
controller.addListener(() {
  print('Selected items: ${controller.value}');
});
