title: Flutter app is not running on real iOS device
body: <p>I have a mobile app in Flutter, it works fine on Android and iOS simulators as well as real devices (except only real iPads with iOS 12.0 and above)</p>
  
  <p>The problem is with running the app in iPad - after the launch I see a white screen for 5 seconds, than a black screen for 3 seconds and that's the finish. The app is not running further. 
  It even does not show a launching screen.</p>
  
  <p>I am testing in Firebase Test Lab and I have done flutter upgrade before every build of product.
  And this is my flutter doctor:</p>
  
  <pre><code>    flutter doctor

  <p>Do you have any ideas what could it be?</p>
