The purpose of demo.dart is to show that if you write unit tests that way, they will fail when your property is violated. The goal is for the user to run dart example/demo.dart and to observe the output on the console to get a feeling of what it is like to use the lib. So I'd rather not catch the exceptions.

If I don't catch the error, then the test fails. I figured that was due to the unittest API at the time not having a way to expect an error to be thrown.
I tried expect(sc.check(badProperty), throwsA(equals('falsified after 11 tests\n' ' argument 1: [true]\n' ' argument 2: [false]\n' ''));
But I couldn't get it to work as expected (no pun intended).

The point is that demo.dart is not a test of the propcheck library. Instead it is a file meant to showcase the library and its tests fail on purpose to showcase the error messages.

Okay, then I think I did the try-catch before I realized enumerators need to be updated. Once that is done, I can retest this propcheck branch to ensure nothing broke (at least according to the tests).

Okay, this is the error that occurs when I run demo.dart. I added it to a gist with a version of the output from the master branch for comparison.

Nit: can you please drop this newline? (Same below.)

Part of a larger effort to migrate to Dart 2, but figured I would separate out the efforts.
