I have a Flutter app that is almost just the basic Android Studio template. When I run the app on the Android emulator or the iOS simulator it works just fine and displays my widgets, and when I make a release build for Android it also works just fine, but when I make a release build for iOS and run it on a iPhone I am only seeing a white/blank screen with no widgets displayed. I have googled this and tried with flutter clean before my build but I can not figure out why this is happening. Please any ideas here?
I have now also tried running on the device from the XCode workspace, there I also get a white/blank screen and this in the console log:

I have ziped my entire project here: https://www.dropbox.com/s/v8olmovqjquxveg/thisisit.zip?dl=0
Thank you

The solution was to delete the ios folder and recreate it by calling "flutter create" on the project folder.
