title: Flutter Android - Gradle task bundleRelease failed with exit code 1
body: <p>I am trying to run the command "<code>flutter build appbundle --verbose</code>" to generate the android version of my app and i am receiving the error "<code>Gradle task bundleRelease failed with exit code 1</code>".</p>
  
  <p>I don't know yet a lot of things about gradle and your dependencies to each package, I have read some stack-overflow answers, refactored the <code>bundle.properties</code> file among other things without success. Here is my build information:</p>
  
  <p><code>flutter build appbundle --verbose</code> part of output</p>
