@SwiftyFlow The code you provided is long and complex. Please try to simplify the example you are providing to have the minimal code to reproduce this issue |

I have an app that is by design always limited to
DeviceOrientation.portraitUp. We don't allow any other orientations except for one screen, which is used as PDF or Image viewer, I want to allow ONLY this view to rotate freely. It works fine on Android but not on iOS.I have added this in initState:
SystemChrome.setPreferredOrientations([DeviceOrientation.portraitUp, DeviceOrientation.landscapeRight, DeviceOrientation.landscapeLeft]);in that case, all good on Android, but no effect on iOS it's like it has only
DeviceOrientation.portraitUpif I do:
That allows landscape rotations but I cannot do portrait...
Any ideas?
Not mentioned but I do do:
