title: Android licenses in Flutter
body: <p>Everything was working fine 4 days ago - I did an update and the licenses stopped going through... what I did so far.</p>
  
  <ol>
  <li>the tools obsolete thing is checked -> does not work</li>
  <li>flutter doctor --android-licenses -> does not work</li>
  <li>sdkmanager --licenses -> did not work</li>
  <li>uninstall and reinstall android at least 3 times -> did not work</li>
  <li>downloaded manually cmdline-tools folder and put in the Sdk folder -> did not work</li>
  <li>delete folder tools and replaced with new one -> did not work</li>
  </ol>
