A base class for stateless widgets that require a view model.
The ViewModelStatelessWidget class is a base class for stateless widgets that require a view model. It provides a factory method to create the view model, and a waiting builder to display a placeholder while the view model is being initialized.
The ViewModelStatelessWidget class is typically used as a base class for stateless widgets that require a view model. The factory method is used to create the view model, and the waiting builder is used to display a placeholder while the view model is being initialized.
