There is one warning which I'd like to fix in a separate CL. The rest is because of package:test predicate(). I think Leaf fixed it in https://github.com/dart-lang/matcher/commit/3625f13698346576da0f5baf44e95abc9c56fb49 R=brianwilkerson@google.com Bug: Change-Id: I060f7ced55dbcc460185916251c47ebbd5c838d3 Reviewed-on: https://dart-review.googlesource.com/3404 Commit-Queue: Konstantin Shcheglov <scheglov@google.com> Reviewed-by: Brian Wilkerson <brianwilkerson@google.com>
