body: <p><strong>Due to character limit, I posted the same problem in Github, Contains detailed operating information。<a href="https://github.com/flutter/flutter/issues/101572" rel="nofollow noreferrer">https://github.com/flutter/flutter/issues/101572</a></strong></p>
  <p>Flutter suddenly runs errors, this is still normal a few days ago, I didn't make any changes during the period.</p>
  <pre><code>FAILURE: Build failed with an exception.
  
  * What went wrong:
  Unable to start the daemon process.
  This problem might be caused by incorrect configuration of the daemon.
  For example, an unrecognized jvm option is used.
  Please refer to the User Manual chapter on the daemon at https://docs.gradle.org/6.7/userguide/gradle_daemon.html

  <p>I have tried some methods, for example:</p>
  <ul>
  <li>'if u are using a laptop and using a mobile hotspot from your laptop turn it off and run the program i hope this will solve your problem it worked for me.'</li>
  <li>delete 'org.gradle.jvmargs=-Xmx1536M' or changed to 'org.gradle.jvmargs=-Xmx1024m'，and restart the project。
  unfortunately, these are useless to me.</li>
  </ul>
