I've been reading through a few posts, and from as far as I can tell, it is possible to change to color of the entire application bar so it doesn't use the default light/dark themes.
However, I'm writing an app where it would be convenient for the color of a single app bar button to change, i.e. On press, colour = default magenta
, and it remains like this untill it has been clicked again.
I have a feeling that this isn't possible, and I'll have to rely on using various images to describe what's going on.
So I'm wondering if there is a solution that doesn't involve doing this?
