title: Flutter app shows a black screen before loading the app
body: <p>I have noticed this problem with flutter apps, when I open a flutter app from cold boot, I see a black screen popping before the actual app is loaded. I have seen the problem with the Newsvoice production app and as well as with a test app I installed.</p>

  <p>Is it a bug in the Flutter SDK?</p>
