Returns an existing ViewModel from the ViewModelStore owned by the ViewModelStoreOwner. If no existing ViewModel is in the store it creates a new one using a factory provided in factory. If factory is null a factory will be retrieved by calling HasDefaultViewModelProviderFactory.getDefaultViewModelProviderFactory on the ViewModelStoreOwner or a default factory will be used expecting a parameter-less constructor for kotlinClass.
