+The following command will generate a coverage report for the Dart packages:

+dart test --coverage=coverage && dart pub global run coverage:format_coverage --lcov --in=coverage --out=coverage/lcov.info --packages=.dart_tool/package_config.json --check-ignore
+```

+We don't yet have a recommended way to view the coverage report but there are
+several extensions available in VSCode.
