title: flutter: command not found
body: <p>I've just finished coding my very first Flutter app but I have a problem: I can't release the APK to publish the app.</p>
  
  <p>I did all of the signing processes, which works properly, but when I write the command <code>flutter build apk</code>, the terminal says: </p>
  
  <pre><code>bash: flutter: command not found
  </code></pre>
  
  <p>After researching for I while I've discovered that the <code>PATH</code> is assigned to Python. That may be because few months I tried Python, but then I uninstalled it. But the Python thing is still is stuck in the Terminal, although the Python app is not in the Mac anymore, and it doesn't allow me to use flutter commands and indeed release the app.</p>
  
  <p>How can I solve this?</p>
