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.
