The React application ceases to function properly as soon as I introduce a textfield

As a newcomer to React, I am facing an issue while working on the front-end UI of a web application. Whenever I try to add a text field to the box I created, the app fails to render anything other than a blank color on the screen.

Here is how it looks:

Without the text field: https://i.stack.imgur.com/tZDSV.png With the text field: https://i.stack.imgur.com/aQ8oA.png

Here is a snippet of my code:

App.js:

import React, { Component} from 'react'
import 'bootstrap/dist/css/bootstrap.min.css';
import './App.css';
import Text1 from './Text1';
import Helmet from 'react-helmet';

import HRLOGO from './images/logo.png';
import ABCLOGO from './images/Group 20399.png';


export default class App extends Component 
{
  state = {};
  render() 
  {
    
    return (
      <div className="hr">
        <div>
          <img src={HRLOGO} alt="" className="container-div"/>
        </div>
        <div>
          <img src={ABCLOGO} alt="" className="container-div2"/>
        </div>
        <Helmet>
          <style>{'body { background-color: #2d4250; }'}</style>
        </Helmet>
        <div>
          <h1 className="InvoiceStyle">Invoice List</h1>
        </div>
        <div className="Rectangle">
        </div>
        <div className="search">
          <Text1></Text1>
          </div>
       
        
        <footer className="Privacy">
          <p>
            <a href="https://www.highradius.com/privacy-policy/">Privacy Policy </a>
             | &#169;Highradius Corporation. All rights reserved.
          </p>
        </footer >
      </div>
    );
  }
}

The css File App.css:

.App {
  text-align: center;
}

// Remaining CSS styles go here...

Text1.js:

import TextField from "@mui/material/TextField";
const Text1 = () => {
    return (
        <form noValidate autoComplete = "off">
          <TextField id="outlined-basic" label="Outlined" variant="outlined" />
        </form>
      );
}
 
export default Text1;

Answer №1

The main issue seems to be the error message Cannot read properties of null (reading 'useContext'). React introduced ambient Context to streamline passing values down your Component hierarchy. Specifically, the TextField component is configured with a variant theme. To access and apply this theme, it needs to locate a ThemeProvider somewhere in its parent component structure. https://mui.com/material-ui/customization/theming/#theme-provider

Solution: Include a ThemeProvider as a parent component within the render method of your App component.

function render() {
   return (<ThemeProvider ...>
      ...
   </ThemeProvider>);
}

By doing this, the TextField component should successfully access the context through the useContext hook. If you encounter any further issues, review the installation and usage guidelines provided for that library: https://mui.com/material-ui/getting-started/usage/
