YaruBackButton alignment behavior is inconsistent

[d-loose]

Depending on whether its style is round or not, the button is wrapped in a Center() widget (see #531). Consequently, ubuntu/app-center#1622 lead to a misalignment in the App Center's search page:

Of course, this can be fixed very easily, but I suppose it's worth making the behavior consistent in yaru 🙂

Ideally, doesn't this look better?

It should be in the leading spot of the appbar, when the page is paned, IMO, just like in the yaru.dart example :) or in the firmware updater / settings app / musicpod / etc
Not to distract from the actual issue, but the back button placement was really questionable from the beginning, IMHO 🙏

That sounds like I good idea, but I can't find that in the yaru example?
Can you send a screenshot?

I just had a local change with this back button in the _TitleBar but got confused by the many ways in app center to access the navkey and reverted it

It could look like in this picture in MusicPod, but then on the snap/deb pages the share and flag buttons need to be moved I suppose

That looks a lot better indeed, what do you think @anasereijo?

[anasereijo]

Indeed! This can work well now that we have approved @Feichtmeier's changes to the layout of the side nav. I am happy to proceed with this, make sure it's present on all pages that can have the back button (search results, app page, etc).

The issue remains but when I read Taha Tesser correctly, this issue with flutters leading widget in app bars is fixed, I think we can removed this internal center here, I'll have a look
