When I try to create a ViewModel in a Composable I get this error:
"java.lang.ClassCastException: java.lang.Object cannot be cast to androidx.lifecycle.ViewModel"
The line is as show in the docs:
val model: ContactSellerViewModel by viewModel()
Any ideas?

[robnik]

And yes, the class inherits from ViewModel...
private class ContactSellerViewModel: ViewModel() { ...

private ?

I tried removing private, but I get the same error.

@robnik what about val model by viewModel<ContactSellerViewModel>() ?

[robnik]

That gives me an error about a missing getValue function and doesn't provide an import suggestion.
I wonder also if I have a Gradle problem: when I click on the stack trace it shows two jars. (Screenshot attached)

Well I got rid of the double jars by listing some explicit deps in my build.gradle file. I can debug step into the viewModel(...) function and see that it's not getting its reified type parameter correctly. The call looks like viewModel(VM::class.java, key, factory) but that first param just Object, not my class. I guess I will manually create my models for now, like: val model = remember { MyViewModel() }.
