@material-ui/styles: Usage in a Class Component?

How does one use the makeStyles API within a class component? The documentation only shows examples for function components.

When I try to use this within a class component’s render method, I get the following error:

Invalid hook call. Hooks can only be called inside of the body of a function component. This could happen for one of the following reasons:
1. You might have mismatching versions of React and the renderer (such as React DOM)
2. You might be breaking the Rules of Hooks
3. You might have more than one copy of React in the same app
See https://fb.me/react-invalid-hook-call for tips about how to debug and fix this problem.

i used withStyles instead of makeStyle like this…

import React from 'react';
import { withStyles } from '@material-ui/core/styles';

const styles = (theme) => ({
  fab: {
    position: 'fixed',
    bottom: theme.spacing(2),
    right: theme.spacing(2),
  },
});

class LoginComponent extends React?Component {
  render() {
    const { classes } = this.props;
    /** your UI components... */
  }
}

export default withStyles(syles)(LoginComponent);

You can’t use the hooks inside a class component. You need a functionnal component or to use the higher order (withStyles).
