    Some class names has their name changed so I was unable to verify if this issue is still valid. I looked in the following files:

    https://github.com/flutter/flutter/blob/master/packages/flutter/lib/src/rendering/sliver_list.dart
    https://github.com/flutter/flutter/blob/master/packages/flutter/lib/src/rendering/sliver_fixed_extent_list.dart
