Defines an access checker that allows specifying a custom method for access.

You should only use it when you are sure that the access callback will not be reused. Good examples in core are Edit or Toolbar module.

The method is called on another instance of the controller class, so you cannot reuse any stored property of your actual controller instance used to generate the output.
