How can I use https://github.com/sass/dart-sass with angular2dart.
For example, I have following component:
styleUrls: const ['login_component.css'],
I don't think there is an easy way currently, because there is no transformer. What you can do is build some watcher or script file that searches all files and compiles them to CSS. You can for example use https://github.com/dart-lang/build but it requires some development. It won't do anything out-of-the-box
I'd suggest using https://pub.dartlang.org/packages/dart_sass_transformer until tooling is available.
