body: <p><code>flutter doctor</code> doesn't work on either Command Prompt or PowerShell window?
  I have been trying to install flutter on windows. I have cloned the Flutter SDK as mentioned in the tutorial. I have added git and the flutter to my path. But still  when I try to run the <code>flutter doctor</code> the command prompt reply with this:</p>
  <pre><code>'where' is not recognized as an internal or external command operable program or batch file.
  Error: Unable to find git in your path
  </code></pre>
