of static method
The NavigationThemeData for context.
Returns Material defaults when no NavigationTheme is present in the
tree above context, so navigation pages always render with valid
colors even in an unconfigured app.
Implementation
static NavigationThemeData of(BuildContext context) {
final inherited = context
.dependOnInheritedWidgetOfExactType<NavigationTheme>();
return inherited?.data ?? const NavigationThemeData();
}
