assets/icons/AshLogo.svg. Source: ash_logo.dart.
API
That’s the whole API — deliberately minimal. The logo always tints (there is no
useOriginalColor here); by default it follows the theme’s contrastStrong, so it’s dark on light surfaces and light on dark ones.
AshLogo.svg lives in assets/icons/ but is not part of the AshIcons enum — the logo is brand lockup, not an icon, and has its own widget.
