Error: The argument type 'FutureOr <dynamic> Function ... can't be assigned to the parameter type 'FutureOr <dynamic> Function

Hi, I am in the process of learning to use Parallel.run but I am running into a problem. I get the error:
Error: The argument type 'FutureOr <dynamic> Function ({int? Test})' can't be assigned to the parameter type 'FutureOr <dynamic> Function ({dynamic item})'.
Apart from the argument, the signature seems to be the same.

My idea is that clicking a button triggers a Parallel.run that works on a local database.

My Function:

FutureOr<dynamic> processWork ({int? Test} async { ... return 0; }

I call her in an ElevatedButton
ElevatedButton (
onPressed: oisvc.getExportJsonsToEmail,
...

and getExportJsonSToEmail is of the form
Future<void> getExportJsonsToEmail () async { final result = await Parallel.run ( processWork, // entryValue: 1, ); log ('result: $ result'); }

Whether I integrate the processWork function inside the static class or outside the class I always get a similar error.

I tested like the example void isOven by putting void processWork. And that's where my disappointments started.

Can you update the doc to use the static Parallel.run method to give a working example please?

Best regards,
