title: Flutter Build Error: Process 'command 'E:\Flutter Apps\flutter\bin\flutter.bat'' finished with non-zero exit value 1
body: <p>I got this error when I try to generate a signed apk in the android studio of my flutter app - <code>Process 'command 'E:\Flutter Apps\flutter\bin\flutter.bat'' finished with non-zero exit value 1</code></p>
  
  <p>I am able to run the app in both emulator and on my device but this error shows up only when I try to build a signed apk.</p>
  
  <pre><code>flutter doctor

  </code></pre>
  
  <p>Any way to fix this?</p>
  
  <p>Tried <code>flutter clean</code></p>
  
  <p>android studio <code>Build &gt; clean project and rebuild project</code>(same error)</p>
  
  <p>I am doing Build > Generated signed apk > apk > release > V1(Jar signature) > Finish to build the app</p>
