Issue with add-to-app #195

Closed mikhail-karan closed 4 years ago

mikhail-karan commented 4 years ago

Hi,

This is a probably a very niche use case but what I'm doing is adding multiple flutter modules to my already created Cordova iOS application. I am then Launching the modules using flutter Add-to-app and PlatformChannel communication from iOS to flutter. I essentially have one Umbrella module that handles the importing and navigation between all my other flutter modules.

The issue is that when I try to run the .scan() function it gives me this error:

2020-03-18 15:03:25.713703-0400 WMVC[1706:1430482] Warning: Attempt to present <UINavigationController: 0x1441eb000> on <CDVViewController: 0x143e09fe0> which is already presenting <FlutterViewController: 0x144979800>

The barcode scanning works on its own, but when I add it to my iOS app (through the umbrella app) it gives me the above error.

Thanks and let me know if you need to see any of my code.
