Update LayoutSubviews BarcodeView to prevent NullReferenceException #78

Closed EssentialNRG closed 2 months ago

EssentialNRG commented 2 months ago

Added a couple of extra null checking mechanisms because sometimes a NullReferenceException is thrown on iOS when switching back-and-fort to a page with the barcode scanner.

Stacktrace:

System.NullReferenceException: Arg_NullReferenceException
     in void BarcodeView.LayoutSubviews()
     in int UIApplication.UIApplicationMain(int, string[], IntPtr, IntPtr)
     in void UIApplication.Main(string[], Type, Type)
     in void Application.Main(string[] args)
