Each example has its own directory, inside which is a short readme and a sole Dart file. To run the example, make sure you have Dart installed and then just do

dart <example directory>/<example name>.dart

Take State, for example:

> dart state/state.dart

The light switch is off.
Toggling the light switch...
  Touching the Stateful...
  Handler of StatusOff is being called!
The light switch is on.

If you have any questions or see any issues, please feel free to file an issue.

Enjoy!
