Do I need to define an InputHandler class even when there are no inputs in my contract?

You will need to provide one to the Configuration, but you don’t necessarily need to create your own class for it. There is an extension function inputHandler { } for this purpose.

The same is true for the EventHandlers. It’s required to provide one to `BasicViewModel`’s constructor, and you should attach one dynamically for other classes, but there’s an eventHandler { } extension function for this too.
