i try to change the font size of the MDTopAppBarTitle.font_size but it didn't work too

[Dariosky-01]

I took a look and did some tests, even if I'm not an expert (and therefore for an objective working method it's always better to try and test what I publish even for you experts) I wasn't able to move the title, it always returns to the left, while the group of buttons on the right move to the right but not if they conflict with the text, and this happens if it is present at the same height, I noticed this when using appbar.type='large'. Changing this parameter brings it down and the buttons move to the right but not the title.

I did some tests because I'm making a summary of the problems I noticed in the various dependencies. I'll post something about it soon.
