import { useWatch } from "https://deno.land/x/netzo@0.4.78/deps/react-hook-form.ts";

useWatch<TFieldValues extends FieldValues = FieldValues>(props: { defaultValue?: DeepPartialSkipArrayKey<TFieldValues>; control?: Control<TFieldValues>; disabled?: boolean; exact?: boolean; }): DeepPartialSkipArrayKey<TFieldValues>

Subscribe to the entire form values change and re-render at the hook level.

useWatch<TFieldValues extends FieldValues = FieldValues, TFieldName extends FieldPath<TFieldValues> = FieldPath<TFieldValues>>(props: { name: TFieldName; defaultValue?: FieldPathValue<TFieldValues, TFieldName>; control?: Control<TFieldValues>; disabled?: boolean; exact?: boolean; }): FieldPathValue<TFieldValues, TFieldName>

Custom hook to subscribe to field change and isolate re-rendering at the component level.
