Good catch. This is handled by FlutterCompletionContributor, which knows nothing about shades.

Unfortunately, this depends on information not available to FlutterCompletionContributor at this time. I filed an issue with the Dart plugin to get it implemented. https://youtrack.jetbrains.com/issue/WEB-55625/Dart:-Missing-color-info-in-CompletionSuggestion
