Use case

In my app I want to give the customer the choice between a dozen of themes. So I am creating a theme changer.
My themes contain various outlinedButtons() with different colors (like in the picture). I know how to set up a theme for all of these outlinedButtons() with a themedata() widget. I also know how to set up a special theme for a particularoutlinedButtons() by wrapping it in a theme() widget. However, setting up the theme changer with a dozens themes is really painful with this type of design.

Proposal

It would be great if we could set up different themes for outlined buttons directly in the themeData() widget. We can do that with text(bodytext1,bodytext2, headline1, headline2...). Something like outlinedButtonTheme1, outlinedButtonTheme2 would be great.
