This issue was originally filed by esprehn@chromium.org

All the code samples on the dart website have:

new Future.delayed(const Duration(seconds:1), () {
  // ...code goes here...
});

but passing an function that takes no arguments to Future.delayed gives an error in the Dart editor about an argument of type 'path/to/my/app.dart' cannot be passed as an argument of type ''.

Also my program always crashes with:

Exception: type '() => dynamic' is not a subtype of type '(dynamic) => dynamic' of 'f'. (http://127.0.0.1:8080/fc-app.dart:22)
Breaking on exception: type '() => dynamic' is not a subtype of type '(dynamic) => dynamic' of 'f'.

so I'm not sure how to use Future, it doesn't seem to work at all.

I use it like in your above code example all the time and it works fine. Can you please provide the complete code for a working example that causes the errors for you.
What Dart version are you using?

I cannot reproduce the reported behavior, so I'm guessing that the issue was fixed.
