NodeFlowActionsMixin<T extends StatefulWidget> mixin

A mixin that provides convenient methods for executing NodeFlow actions from within stateful widgets.

This mixin is useful for widgets that need to programmatically trigger NodeFlow actions, check if actions can be executed, or display keyboard shortcuts in UI elements like menus or tooltips.

Example usage:

class MyWidget extends StatefulWidget {
  const MyWidget({super.key});

  @override
  State<MyWidget> createState() => _MyWidgetState();
}

class _MyWidgetState extends State<MyWidget> with NodeFlowActionsMixin {
  NodeFlowController? _controller;

  @override
  NodeFlowController? get nodeFlowController => _controller;

  void _handleDelete() {
    if (canExecuteAction('delete_selection')) {
      executeAction('delete_selection');
    }
  }

  @override
  Widget build(BuildContext context) {
    final shortcut = getActionShortcut('delete_selection');
    return TextButton(
      onPressed: _handleDelete,
      child: Text('Delete ($shortcut)'),
    );
  }
}
