title: zsh: command not found: flutter?
body: <p>I've tried to install flutter multiple times, and could run flutter doctor once, but after closing the terminal I couldn't. Don't know how I did it, and this keeps coming on the screen.</p>
  <pre><code>user@users-MacBook-Pro flutter % export PATH=&quot;$PATH: /Users/user/Desktop/flutter/bin&quot;
  user/users-MacBook-Pro flutter % flutter --version
  zsh: command not found: flutter
  user@users-MacBook-Pro flutter %  
  </code></pre>
  <p>So I have changed my path, changed the shell to -zsh, because I work with macOS Catalina, but nothing seems to work. What should I do?</p>
