@isoos – not sure what you need to do to make the publish check happy...

[isoos]

Package validation found the following potential issue:
* The name of "lib/builder.dart", "builder", should match the name of the package, "shelf_router_generator".
  This helps users know what library to import.

@jonasfj: should we also include the lib/shelf_router_generator.dart file exporting builder.dart?

[kevmoo]

Oh! We should just ignore that bit, then. This is just how we do builders.
