react-define-form/lib/FormSpyProps.d.ts

React define form offers alternative typescript bindings for [react-final-form](https://github.com/final-form/react-final-form). It requires you to "define" a form type, specifying the type of the form data.

import { FormState, FormSubscription } from 'define-form';
import RenderableProps from './RenderableProps';
import { SubsetFormApi } from './FormProps';
export interface FormSpyRenderProps<FormData, ErrorValue> extends FormState<FormData, ErrorValue>, SubsetFormApi<FormData> {
}
export default interface FormSpyProps<FormData, ErrorValue> extends RenderableProps<FormSpyRenderProps<FormData, ErrorValue>> {
    onChange?: (formState: FormState<FormData, ErrorValue>) => void;
    subscription?: FormSubscription;
}
