Map<String, String> env = new Platform().environment(); Unfortunately, this is a bit hard to test at this point. I will move on to implement support for providing an environment to processes that are started. At that point we can test it properly. Another follow-up change will be to remove the instantiation for Platform. I would like this to be just Map<String, String> env = Platform.environment(); R=sgjesse@google.com BUG=dartbug.com/752 TEST= Review URL: https://chromiumcodereview.appspot.com//10112002 git-svn-id: https://dart.googlecode.com/svn/branches/bleeding_edge/dart@6646 260f80e4-7a28-3924-810f-c04153c831b5
