[super_drag_and_drop] Getting 'Invalid argument' error in macOS, but not on web

[LeoRc01]

this is the code snippet:

final child = ....;

return DragItemWidget(
        dragItemProvider: (request) async {
          final item = DragItem(localData: const MyCustomModel(name: 'NAME'));

          return item;
        },
        allowedOperations: () => [DropOperation.move],
        child: DraggableWidget(child: child),
      );
     

and this is the model i'm trying to use;

class MyCustomModel {
  const MyCustomModel({
    required this.name,
  });

  final String name;

  @override
  bool operator ==(Object other) =>
      identical(this, other) ||
      other is MyCustomModel &&
          runtimeType == other.runtimeType &&
          name == other.name;

  @override
  int get hashCode => name.hashCode;
}

but when I try to Drag the item, on macOS I get this error, but on web it works just fine.
