svelte-multistep-form VS redux-form

I was looking for a svelte library, who can help me to create multistep form and I have found out this abandoned library : https://github.com/edenriquez/svelte-multistep-form.

Handling form defaults

kyleboyle's proposal here simply doesn't work. When I call nextProps.handleSubmit from componentWillReceiveProps, I get this familiar error, Uncaught Error: You must either pass handleSubmit() an onSubmit function or pass onSubmit as a prop

redux-form is a very compelling library for providing redux bindings for forms in a react application, which should be super-convenient. Unfortunately, using the library's own examples, I'm failing to actually bind anything, which is super in-convenient.
