useRef()
is among react hooks which are meant to be used in Functional components. But if you want to create a reference in a class-based component, you can do it from the class constructor like the code below:
constructor(props) {
super(props);
this.myRef = React.createRef();
}
OR
constructor(props) {
super(props);
this.state = { myRef: React.createRef() }
}
Check React.createRef().
