[bug] react-select-fetch's `url` is improperly marked required. It is only required if you don't override `get`.

[soteri-scottmmjackson]

url is marked required on react-select-fetch components. No it isn't. That isn't true.

Or, more specifically, it's only true iff get isn't overridden. Then it's... the url parameter that gets injected into your get method's first parameter. Whatever. My get method can easily hardcode that, and then I have to use one less prop. Or I would, if it wasn't marked as a required prop on the component.

Why don't we, as a compromise, mark url nullable and then say about here we do a runtime check to make sure we actually have a url or throw.
