Hello, I am trying to “multiplatform” the ViewModel class from androidx:

public abstract class ViewModel {
    protected void onCleared() {
    }
}

I hoped the following would work:

expect abstract class ViewModel {
     protected fun onCleared()
}

And on Android declare it this way:

actual typealias ViewModel = androidx.lifecycle.ViewModel

But because protected means different things in Kotlin and Java, I get the following error: protected final expect fun onCleared(): Unit is incompatible because visibility is different from protected/*protected and package*/ open fun onCleared(): Unit. Am I stuck here or is there a way to go around this?
