maybeOf static method
- BuildContext context
The closest instance of DefaultTabController that encloses the given context, or null if none is found.
Typical usage is as follows:
link
TabController? controller = DefaultTabController.maybeOf(context);Calling this method will create a dependency on the closest
DefaultTabController in the context, if there is one.
See also:
- DefaultTabController.of, which is similar to this method, but asserts if no DefaultTabController ancestor is found.
Implementation
static TabController? maybeOf(BuildContext context) {
return context.dependOnInheritedWidgetOfExactType<_TabControllerScope>()?.controller;
}
