title: Blank Screen in running flutter app in release mode
body: <p>Pretty much this issue <a href="https://github.com/flutter/flutter/issues/36247" rel="noreferrer">https://github.com/flutter/flutter/issues/36247</a> .
  Looking for any support here. </p>
  
  <p>PLEASE NOTE ISSUE WITH IOS ONLY.</p>
  
  <p>The app works perfectly in the simulator and also when connected via USB. 
  But when I build the app for release and distribute through testflight. It is showing blank screen.</p>
  
  <p>I have a simple log to create on my home page which never gets triggered. So it must be before that the app is getting terminated or something.</p>
  
  <p>The app shows no crashes( running crashlytics)</p>
  
  <p>Looking for some help.</p>
