I've installed Dart according to instructions from the official website (https://www.dartlang.org/tools/debian.html). To be more exactly:

$ sudo apt-get update

$ sudo apt-get install apt-transport-https

# Get the Google Linux package signing key.

$ sudo sh -c 'curl https://dl-ssl.google.com/linux/linux_signing_key.pub | apt-key add -'

# Set up the location of the stable repository.

$ sudo sh -c 'curl https://storage.googleapis.com/download.dartlang.org/linux/debian/dart_stable.list > /etc/apt/sources.list.d/dart_stable.list'

$ sudo apt-get update

$ sudo apt-get install dart

Installation was successful, but some time later I found that there is no other related commands like pub, dart2js.

pub: command not found

dart2js: command not found

What's wrong?

OS: Ubuntu 14.10
