Flutter app crashes randomly (io.flutter.1.gpu (8): signal SIGABRT) on ios 13 but not on android or iphone 5s with earlier ios

When I navigate around the app it crashes on random screens and in XCode I get the message: io.flutter.1.gpu (8): signal SIGABRT

The stacktrace is:

I have no clue on how to fix this as I don't see a correlation from my flutter/dart code to the error. I would greatly appreciate any possible explanation for a cause/fix or guidance on how to figure it out.
