How to transform the Material UI functional component Mini variant drawer into a class component in ReactJS

I have been working with the mini variant drawer component from the official material-ui website and I am encountering some issues when trying to convert it into a class component. The errors seem to be related to hooks and are occurring within the node modules. Has anyone successfully used this component in a class-based component before?

  import React from 'react'
  import clsx from 'clsx'
  // More imports...
  
  // Component code...

If you are working with a class component, remember that hooks cannot be used in them. Instead, create a state property within your class and utilize that to manage state.

According to the React documentation: Converting a Function to a Class

You can easily convert a function component like Clock into a class by following these five steps:

  • Create an ES6 class with the same name that extends React.Component.
  • Add a render() method which is initially empty.
  • Transfer the code from the original function into the render() method.
  • Adjust props to use this.props within the render() method.
  • Delete any remaining unnecessary functions.
class Clock extends React.Component {
  constructor(props) {
    super(props);
    this.state = {date: new Date()};
  }

  render() {
    return (
      <div>
        <h1>Hello, world!</h1>
        <h2>It is {this.state.date.toLocaleTimeString()}.</h2>
      </div>
    );
  }
}
