dart - pub get does not install redstone package -

i have issue pub. i'm new in dart. followed instructions on redstone web page (http://redstonedart.org/doc/installation.html) use redstone in server project.

i'm using webstorm. here copy-paste of pubspec.yaml :

name: ndolo_server  dependencies: redstone: 

when run pub get on application root folder or on webstorm, pub seem work correctly (it displays "got dependencies") package folder stay empty. ran cache repair (pub cache repair), here seems work correctly, package folder stay empty.

when run pub --trace, following output :

e:\devel\webapps\ndolo2\server> pub --trace resolving dependencies... got dependencies! e:\devel\webapps\ndolo2\server> 

can me?

thank!

you need add space or tab before redstone....
see https://www.dartlang.org/tools/pub/pubspec.html more details.
