maybeOf static method
- BuildContext context
Retrieves the HeroController from the closest HeroControllerScope ancestor, or null if none exists.
Calling this method will create a dependency on the closest
HeroControllerScope in the context, if there is one.
See also:
- HeroControllerScope.of, which is similar to this method, but asserts if no HeroControllerScope ancestor is found.
Implementation
static HeroController? maybeOf(BuildContext context) {
final HeroControllerScope? host = context.dependOnInheritedWidgetOfExactType<HeroControllerScope>();
return host?.controller;
}
