  <p>Dear Developer,
  We identified one or more issues with a recent delivery for your app, &quot;AppName&quot;. &gt; Please correct the following issues, then upload again.</p>
  <p>ITMS-90338: Non-public API usage - The app references non-public
  symbols in Frameworks/Flutter.framework/Flutter: _ptrace. If method
  names in your source code match the private Apple APIs listed above,
  altering your method names will help prevent this app from being
  flagged in future submissions. In addition, note that one or more of
  the above APIs may be located in a static library that was included
  with your app. If so, they must be removed. For further information,
