Sorry, I wasn’t trying to be sarcastic. And as I said, I understand the problem you are talking about.

I would like to add that Flutter (being reactive) is not particularly trying to maintain MVC structure. There is significantly less need for controllers when the view (widget tree) is immutable.

And I believe that separation of concerns is not automatically always a good thing. It can sometimes cause problems itself. For example, CSS and HTML, which tried to completely separate layout from content. That turned out to not be a particularly helpful thing in the mobile world.
