Problem with pubspec.yaml and duct

[Deleted user]

Here is my pubspec.yaml file:

name: "CSGOBlinks"
dependencies:
  polymer: "^1.0.0-rc.3"
  web_components: ^0.12.0
  reflectable: "^0.3.3"
  polymer_elements: "^1.0.0-rc.2"
  duct:
      git: git://github.com/petrhosek/duct.git ">=0.4.3"
transformers:
- web_components:
    entry_points:
      - web/index.html
- reflectable:
    entry_points:
      - web/index.dart

and here is the output of pub install. Is that something that can be fixed? I have no clue

➜  CSGOBlinks_front git:(dev) ✗ pub install
