title: Flutter Build APK: Failed - Execution failed for task ':keyboard_visibility:verifyReleaseResources'
body: <p>I am facing a strange problem after I have updated flutter or android studio. I was able to run flutter build apk command before. But I can export ipa for iOS version of same application.</p>
  <p>I have updated the latest versions of packages. Checked &quot;compilesdkversion 28&quot;. Everything looks ok I think.</p>
  <p>You can see my failed packages below.</p>
  <ul>
  <li>keyboard_visibility</li>
  <li>connectivity</li>
  </ul>
  <p>Here is the error output;</p>
