  • Check whether android command line tools are installed or not. You can follow this github wiki and solve the issue: https://github.com/flutter/flutter/issues/57017 – Midhun MP Dec 23 '20 at 10:29

    Okay so here's how I solved it . 1) Install Android Studio 2) Go to SDK Manager > SDK Platforms > download SDK for Android 11(R) and Android 10(Q) 3) go to SDK tools tab and download Android SDK Command line tools . And the errors were gone ! I guess the command line tools were missing which i forgot to reinstall that caused this issue . Thanks alot – Rudr Thakur Dec 23 '20 at 10:43
  • Happy to know that it worked. Happy Coding!!! – Midhun MP Dec 23 '20 at 10:46

OK!

  1. I see no IDE (Android Studio / VS Code)
  2. you need to download one of the Android SDK to continue
  3. No Connected devices (which also means, you didn't enable the web also)
  4. After resolving these you should go for android licenses.
