ViewModelStoreOwnerFactory

public static final @NonNull ViewModelStoreOwner create(
    @NonNull ViewModelStore viewModelStore,
    @NonNull SavedState defaultArgs,
    @NonNull CreationExtras defaultCreationExtras,
    @NonNull ViewModelProvider.Factory defaultFactory
)

Creates a ViewModelStoreOwner by composing a store, factory, and creation extras.

    @NonNull ViewModelStore viewModelStore,
    @NonNull SavedStateRegistryOwner savedStateRegistryOwner,
    @NonNull SavedState defaultArgs,
    @NonNull CreationExtras defaultCreationExtras,
    @NonNull ViewModelProvider.Factory defaultFactory
)

Creates a ViewModelStoreOwner that also acts as a SavedStateRegistryOwner, composing a store, state registry, lifecycle, factory, and creation extras.

While the simpler ViewModelStoreOwner factory handles standard ViewModels, this overload provides the necessary infrastructure for ViewModels that rely on SavedStateHandle. By bundling the SavedStateRegistryOwner with the store, it creates a fully equipped scope capable of properly wiring up state-saving mechanisms for its ViewModels.
