title: Is there a way to pass a primitive parameter by reference in Dart?
body: <p>I would like to pass a primitive (int, bool, ...) by reference.  I found a discussion about it (paragraph "Passing value types by reference") here: <a href="https://groups.google.com/a/dartlang.org/forum/#!topic/misc/iP5TiJMW1F8/discussion" rel="noreferrer">value types in Dart</a>, but I still wonder if there is a way to do it in Dart (except using an object wrapper) ? Any development ?</p>
