The body of the constructor assigns "Alice" to the name property. When the

Another option is to build and serve the app using <code>pub serve</code>,
and then to run it by visiting http://localhost:8080/index.html in a browser.
The JavaScript generated using this option is large, for now;
it'll be much better soon, when a transformer becomes available
