Federated logout using flutter sdk

Hi, I’m trying to implement a federated logout in my flutter app using auth0 sdk, I need it especially for testing but I’ll most likely need it for production as well. My problem is that every documentation or = previous post I see says that you have to modify a logout url to include a ?federated parameter in the query, however in the flutter sdk you are exposed to a logout method directly which doesn’t (or I wasn’t able to find) allow you to make this modification. Is there a way to achieve this using the sdk? Or maybe I can make direct calls to auth0 API, I have no problem with that either, I just want to achieve federation (at least while I’m testing, to see how user experience turns out)
