Duvet generates nice-looking coverage reports for your Dart projects.

Add Duvet to your project by adding the following to your pubspec.yaml:

dev_dependencies:
  duvet: ^1.0.0

You can also install duvet globally with the following:

$ pub global activate duvet

Once added to a project, you can generate a coverage report by running:

$ pub run duvet:duvet_cover

If you installed duvet globally, you can generate a report by running:

$ duvet_cover

duvet will then run your tests and collect coverage, outputting the report to a coverage directory. You can also pass the --serve option to automatically start a webserver to access the coverage reports.

You can view a sample coverage report for the dart_style package here.

duvet works by running the test package against your project, and then using the coverage package to collect coverage information. It then assembles reports using hyper, and serves the reports using shelf.
