BOT!

The Dart Bag-of-Tricks

A collection of (mostly) general libraries to make working with Dart more productive.

Starting by porting bits of the PL javascript library and Google's Closure javascript library to enable some interesting scenarios.

Projects using BOT

Try It Now

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. For example:

dependencies:
  bot: ">=0.9.0 <0.10.0"    # works with M2 SDK (r16251)

Versions change within the range when we release small bug fixes, but it changes outside of the range on any breaking change. 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:

Versioning

  • We follow Semantic Versioning.
  • We are not planning a V1 for BOT until Dart releases V1. In the mean time, the version will remain 0.Y.Z. Changes to the minor version - Y - will indicate breaking changes. * Changes to the patch version - Z - indicate non-breaking changes.

Dart SDK dependency

  • We're going to try to keep BOT in line with the latest integration build of the Dart SDK and Editor.
  • At this point, each SDK release tends to introduce breaking changes, which usually require breaking changes in BOT.
  • Keep an eye on the changelog to see how BOT aligns with each SDK release.
