While running apk with 1.0.1 lib it crashes with missing implementation medhod getInfoModel(). Is there any other dependency which should be included for galaxy fold device?

Hello, I made this simple example. When I debugged this application everything worked fine. As soon as I wanted to deploy it in release mode an error ("java.lang.AbstractMethodError: abstract method "void androidx.window.sidecar.SidecarInterface$SidecarCallback.onDeviceStateChanged(androidx.window.sidecar.SidecarDeviceState)"") came which I resolved by adding dependencies { implementation "androidx.window:window:1.0.0-beta04" } to the build.gradle file. Now the app runs but it seems to not think the device is not Spanned when it is spanned so I always just see the first child from TwoPageLayout.

MultiScreenInfo(builder: (info) {
        print(info.surfaceDuoInfoModel.isSpanned);
}); **returns false;**

SurfaceDuoPlatformHandler.getIsSpanned().then((value) => print(value)); **returns true**

It would be helpful to have a way to know if an app has been spanned from a particular widget. For example, let's say we have a list of items as the child for our TwoPageLayout, and a DetailView widget representing the contents of an item in the list. When not spanned, you'll see the list of items, and tapping on an item brings you into the DetailView to see the contents for that item, like so:

When spanned, you'll see the list on the left and the DetailView on the right, like so:

This is all fine, except when spanning from within the DetailView. So when not spanned, you tap on an item, and from the DetailView you span the app. You'd expect to see the list on the left again, right? What actually happens is that the DetailView will span across both screens:

It would therefore be useful to be able to tell when we have spanned from a particular widget.
