Flutter 应用程序卡在溅射屏幕 ios，但应用程序可在 Android 设备上运行

Question

I got a very annoying bug, my app works perfectly on Android devices, but In ios it gets stuck on the splash screen. I don't know how to fix this, in any possible ways that cause the problem? //// I'm testing my ios app in VMware MacOs Catalina, Simulator

How do you think bug comes from code or from system? Or how I can identify what cause the problem, any possible ways?
