dart: get object within anonymous function

Question

I want to access the object itself within a listen-callback.

SomeObject o = new SomeObject()
    ..onEvent.listen((Event ev){

        //now I want to access Object o.

    });

It works if I call onEvent.listen after o is created, but I want to access it by the constructor, because some events are fired during construction. Is it somehow possible to access the object within this callback?!

Answer 1

What you try to do is recursive initialization.
You can do it like:

SomeObject o;
o = new SomeObject()
    ..onEvent.listen((Event ev){

        //now I want to access Object o.

    });
