How do I do the equivalent of setTimeout + clearTimeout in Dart?

I'm porting some JavaScript to Dart. I have code that uses window.setTimeout to run a callback after a period of time. In some situations; that callback gets canceled via window.clearTimeout.

What is the equivalent of this in Dart? I can use new Future.delayed to replace setTimeout, but I can't see a way to cancel this. Nor can I find away to call clearTimeout from Dart.

As answered on SO. Use Timer for a timeOut that can be cancelled. Use Delayed for one you don't expect to need to cancel.
