title: Invalid depfile: Flutter
body: <p>I am following a tutorial from a udemy course and recently I built a new pc so the hard drive that stored my code is secondary right now. When I compile the code, it gives me the following error. To explain it better, I am posting a picture of one warning in my code but I am pretty sure it is an error flutter is making as it usually does with imports. <a href="https://i.stack.imgur.com/TZqTx.png" rel="noreferrer">Error in Code</a>
      I have tried running a test app by making a default app from cmd and that works fine. So obviously, flutter doctor shows no error. the error is repetitive and long so I am pasting some of it below.</p>
  
  <p>The error-</p>
