maybeOf static method
The strip bars below context should use, or null where they are
horizontal — on every device but iPhone Duo, in inner portrait, with no
GlassNavigationShell above, with GlassVerticalBarBehavior.disabled,
or under GlassVerticalBar.disabled.
Implementation
static GlassVerticalBarData? maybeOf(BuildContext context) =>
context.dependOnInheritedWidgetOfExactType<GlassVerticalBar>()?.data;
