when I run the official example https://popper.js.org/react-popper/v2/
import React, { useState } from 'react';
import { usePopper } from 'react-popper';
const Example = () => {
const [referenceElement, setReferenceElement] = useState(null);
const [popperElement, setPopperElement] = useState(null);
const [arrowElement, setArrowElement] = useState(null);
const { styles, attributes } = usePopper(referenceElement, popperElement, {
modifiers: [{ name: 'arrow', options: { element: arrowElement } }],
});
return (
<>
Reference element
);
};
I got a ts error as below:
`ERROR in src/components/UserSearch/test.tsx:18:12
TS2322: Type 'Dispatch<SetStateAction>' is not assignable to type 'LegacyRef | undefined'.
Type 'Dispatch<SetStateAction>' is not assignable to type '(instance: HTMLDivElement | null) => void'.
Types of parameters 'value' and 'instance' are incompatible.
Type 'HTMLDivElement | null' is not assignable to type 'SetStateAction'.
Type 'HTMLDivElement' is not assignable to type 'SetStateAction'.
Type 'HTMLDivElement' provides no match for the signature '(prevState: null): null'.
