maybeOf static method

DrawerController? maybeOf(BuildContext context)

The closest instance of DrawerController that encloses the given context, or null if none is found.

Typical usage is as follows:

DrawerController? controller = DrawerController.maybeOf(context);

Calling this method will create a dependency on the closest DrawerController in the context, if there is one.

See also:

• DrawerController.of, which is similar to this method, but asserts if no DrawerController ancestor is found.
