How to style components using makeStyles and still have lifecycle methods in Material UI?

128

I get the below error whenever I try to use makeStyles() with a component with lifecycle methods:

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

Below is a small example of code that produces this error. Other examples assign classes to child items as well. I can't find anything in MUI's documentation that shows other ways to use makeStyles and have the ability to use lifecycle methods.

    import React, { Component } from 'react';
    import { Redirect } from 'react-router-dom';

    import { Container, makeStyles } from '@material-ui/core';

    import LogoButtonCard from '../molecules/Cards/LogoButtonCard';

    const useStyles = makeStyles(theme => ({
      root: {
        display: 'flex',
        alignItems: 'center',
        justifyContent: 'center',
      },
    }));

    const classes = useStyles();

    class Welcome extends Component {
      render() {
        if (this.props.auth.isAuthenticated()) {
          return <Redirect to="/" />;
        }
        return (
          <Container maxWidth={false} className={classes.root}>
            <LogoButtonCard
              buttonText="Enter"
              headerText="Welcome to PlatformX"
              buttonAction={this.props.auth.login}
            />
          </Container>
        );
      }
    }

    export default Welcome;

Hi instead of using hook API, you should use Higher-order component API as mentioned here

I'll modify the example in the documentation to suit your need for class component

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

const styles = theme => ({
  root: {
    background: 'linear-gradient(45deg, #FE6B8B 30%, #FF8E53 90%)',
    border: 0,
    borderRadius: 3,
    boxShadow: '0 3px 5px 2px rgba(255, 105, 135, .3)',
    color: 'white',
    height: 48,
    padding: '0 30px',
  },
});

class HigherOrderComponentUsageExample extends React.Component {
  
  render(){
    const { classes } = this.props;
    return (
      <Button className={classes.root}>This component is passed to an HOC</Button>
      );
  }
}

HigherOrderComponentUsageExample.propTypes = {
  classes: PropTypes.object.isRequired,
};

export default withStyles(styles)(HigherOrderComponentUsageExample);

I used withStyles instead of makeStyle

EX :

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

const useStyles = theme => ({
        root: {
           flexGrow: 1,
         },
  });

class App extends Component {
       render() {
                const { classes } = this.props;
                return(
                    <div className={classes.root}>
                       Test
                </div>
                )
          }
} 

export default withStyles(useStyles)(App)
