title: Flutter trying to compile my deleted Project
body: <p>I'm currently working on  a Flutter project named 'health_service' but Flutter is trying to compile other project named 'flare_test1' which was deleted and is in Trash.</p>
  
  <p>I thought there might be a problen in cache.
  So I did <code>flutter clean</code> but the result is same.</p>
  
  <p>Here's output of <code>flutter doctor</code></p>
