Incentive

Most of the languages(i.e. Java, Scala, Kotlin, Swift) can specify a different syntax highlighting color on Interface,class, abstract class, protocol in Intellij IDE.

• It is a common language features provided by the "Analysis Server" out of box.
• This feature helps programmers to distinguish the typing when they are writing/reading code.

Example: Kotlin

Become Inefficient when reading codes that are written by others

without this feature, Coder will lose a lot of valuable information that can improve productivity.

IDE Features Request

I submitted "Feature request: Dart syntax highlight enhancement for mixin & abstract class" and got responded that they use Dart Analysis Server to do syntax highlight.

Dart code highlighting is powered by the Dart Analysis Server, a tool from the Dart SDK. IDE only highlights what the server tells it to highlight. The variety of highlighting types is also managed by the server. Current server API doesn't have separate highlighting types for mixins and abstract classes. See HighlightRegionType definition.

You might want to file a request in the Dart SDK's issue tracker and paste a link to the issue here. Once it's done on the server end we'll be able to support it on the Dart plugin end. -- Alexander Doroshko 1 Apr 2019 17:34

Disclaimer: I have built an universal color scheme for Intellij IDEs across different languages.

@kevmoo, I think area-analyzer would be the right label here. See my comment quoted at the end of the issue description.
