CupertinoSliverNavigationBar should respect accessibility text scaling #167248
Description
Use case
When the text scale is changed in the iOS settings app, CupertinoSliverNavigationBar does not respect the new text scale.
CupertinoNavigationBar allows contents to be text-scaled if the contents are wrapped in a MediaQuery with text scaling. CupertinoSliverNavigationBar does not.
Proposal
Update CupertinoSliverNavigationBar to respect accessibility text scaling.
In the photos below, notice how the nav bar remains unscaled.
