Dart pub
Starting by porting bits of the PL javascript library and Google's Closure javascript library to enable some interesting scenarios.
The Dart Bag-of-Tricks ( BOT ) is hosted on pub.dartlang.org. Add the BOT package to your pubspec.yaml file, selecting a version range that works with your version of the SDK. Always check the BOT page on pub to find the latest release.
See the changelog to find the version that works best for you.
If you'd like to track bleeding edge developments, you can reference the the GitHub repository directly:

Package is pre-v1 release.
While there is nothing inherently wrong with versions of
0.*.*, it usually means that the author is still experimenting with the general direction API.
