Dart templates not seen in new Dart project - dart

Question

I am trying to use Webstorm for my Dart project since it is recommended. I have installed it and point it to the Dart sdk and dartium path. On creating a new Dart project, I only see Dart Web App and Dart Command Line App. No polymer template or any other template. What can I do to see those template.
RELEVANT VERSIONS OF DART OFFERINGS:
Dart 1.11.0 (ref 65704b3) DEV (SDK)
Dart 1.11.0 (ref 65704b3) (STABLE) DARTIUM
EDIT 1 (relates to first comment by Gunter)
I deleted and attempted to reinstall stagehand but I am getting the following errors

Several attempts simply result in the same error.
I did a pub cache repair but the result is the same.
