title: I cloned a flutter project from github but I am unable to run it
body: <p>I have cloned a flutter project from Github (project link: <a href="https://github.com/abuanwar072/Covid-19-Flutter-UI.git" rel="nofollow noreferrer">https://github.com/abuanwar072/Covid-19-Flutter-UI.git</a>) and I have not changed anything in the code. I have cloned it in VS Code however when I try to run it on my android emulator, I run into an error.</p>

  <p>I have already tried updating my android SDK from the android studio and running flutter doctor (It showed something about licenses so I fixed it by saying yes to all licenses it showed me). It still is producing the above message. I am not sure I did the SDK update part correctly but please help in understanding how to do it correctly.</p>
