How to change screen orientation in Maui?

Question

In Xamarin there was a class called DeviceInfo with a settable CurrentOrientation property.
This class appears to not exist for Maui. I can't figure out how you can change the screen orientation and I can't find an example that can show how's it's accomplished. Can anyone here provide me with some guidance. Thanks in advance.

Hello,​

Maui doesn't provide a cross platform property to change the screen orientation, but Maui gives access to the underlying native API

Please refer to this document about Invoke platform code

Android we can change the Orientation by RequestedOrientation, set the ScreenOrientation directly.

   //Set ScreenOrientation to Landscape  
                   MainActivity.Instance.RequestedOrientation = ScreenOrientation.Landscape;  
     
   //Set ScreenOrientation to Portrait  
                   MainActivity.Instance.RequestedOrientation = ScreenOrientation.Portrait;  

Note: MainActivity.Instance comes from MainActivity.cs, I define a public static property

iOS: we can use UIDevice.CurrentDevice.SetValueForKey and set it for different Orientation.

   //Set ScreenOrientation to Landscape  
                   UIDevice.CurrentDevice.SetValueForKey(NSNumber.FromNInt((int)(UIInterfaceOrientation.LandscapeLeft)), new NSString("orientation"));  
   //Set ScreenOrientation to Portrait  
                   UIDevice.CurrentDevice.SetValueForKey(NSNumber.FromNInt((int)(UIInterfaceOrientation.Portrait)), new NSString("orientation"));

for android, just add

ScreenOrientation= ScreenOrientation.Landscape  

in Platforms\Android\mainActivity.cs, before public class MainActivity : MauiAppCompatActivity it will look like this:

[Activity(Theme = "@style/Maui.SplashTheme", MainLauncher = true, ScreenOrientation= ScreenOrientation.Landscape, ConfigurationChanges = ConfigChanges.ScreenSize | ConfigChanges.Orientation | ConfigChanges.UiMode | ConfigChanges.ScreenLayout | ConfigChanges.SmallestScreenSize | ConfigChanges.Density)]

Hi, I tried the iOS solution, unfortunately it doesn't work for iOS / .NET 7
