dart - How do I pass multiple entry_points to polymer transformer in pubspec.yaml?

Question

Now that pub build supports building Polymer apps, how do I pass multiple entry_points to the Polymer transformer in my pubspec.yaml file?

When I try to build with this syntax both files have errors:

transformers:
- polymer:
    entry_points: web/reports.html, web/index.html

And when I try passing them in the following manner, only the last listed entry point is built:

transformers:
- polymer:
    entry_points: web/index.html
    entry_points: web/reports.html

In YAML, a sequence is created by wrapping a comma separated list in square brackets [ 0, 1, 2, ] or by putting each entry on a line by itself prepended by a hyphen - So your example would look like this:

transformers:
- polymer:
    entry_points: [ web/index.html, web/reports.html ]

Or this:

transformers:
- polymer:
    entry_points: 
      - web/index.html
      - web/reports.html
