Take Picture - First one works, second one (different screen) fails

[mwawrusch]

Tested this on ios, we have the following setup:
User takes selfie with front camera. Works.
Transitions to another page
User takes photo of license with back camera - fails with exception below.

Any help is very much appreciated.

The following PlatformException was thrown while de-activating platform stream on channel
plugins.flutter.io/camera/imageStream:
PlatformException(error, No active stream to cancel, null)
When the exception was thrown, this was the stack:
