title: Were can I find "flutter pub list" or "flutter pub search" command line tools?
body: <p>Where can I find a command line tool for searching and listing installed packaged versions and available upgrade versions? </p>
  
  <p>I can't think of any other package management tool that doesn't include commands to list installed versions or find available upgrades without actually upgrading.</p>
  
  <p>For example, if my pubspec.yaml restricts a version, there is no easy way to check which of my pinned packages could be upgraded if I lift the restriction. Similarly, it might be possible to see what versions of a particular package may be available at the command line.</p>
  
  <p>I'd prefer to use a command line tool because it is a vastly faster workflow than needing to check a website for every package you might be using or have inherited via a dependency.</p>
