Does not work on iOS

[besserwisser]

I tested it on an iPad (iOS 12.3.1) and it had no effect. Not in my app and not with the example app.

Screen rotation is allowed in iOS.

Here a screen recording of the example app: https://streamable.com/vve0p

Hey @besserwisser
thats no a problem with iOS, it's a problem with iPad's in general, which is an offical flutter issue.

Nope, I did not fix it. You have to manually rotate the iPad.

setPreferredOrientations method
Future setPreferredOrientations (
List orientations
)
Specifies the set of orientations the application interface can be displayed in.

The orientation argument is a list of DeviceOrientation enum values. The empty list causes the application to defer to the operating system default.

Limitations
This setting will only be respected on iPad if multitasking is disabled.

You can decide to opt out of multitasking on iPad, then setPreferredOrientations will work but your app will not support Slide Over and Split View multitasking anymore.

Should you decide to opt out of multitasking you can do this by setting "Requires full screen" to true in the Xcode Deployment Info.
code here

void main() async {
  AutoOrientation.landscapeLeftMode();
  runApp( MyApp());
}
