React - Material UI Typography how to break long string to multiple lines

I'm using ReactJS and the components library called MaterialUI. I'm having an issue with the Typography component.

What happens is that if I write a long text it exceed its container and doesn't go on a new line:

import React from "react";
import { Redirect } from "react-router";
import { withRouter } from "react-router-dom";

import Container from "@material-ui/core/Container";
import CssBaseline from "@material-ui/core/CssBaseline";
import Typography from "@material-ui/core/Typography";

function Homepage() {
  return (
    <div>
      <React.Fragment>
        <CssBaseline />
        <Container fixed>
          <Typography variant="h1" component="h2" align="center">
            123 456 789 qwertyuiopasdfghjklzxcvbnm
          </Typography>
        </Container>
      </React.Fragment>
    </div>
  );
}

export default withRouter(Homepage);

This happens in the mobile mode and also in desktop mode.

Do you know how to fix this behavior? I would like the long words will be split on a new line if the maximum width of the container has been reached.

Solution

Use word-wrap, it works for Material-UI's Typography.

wordWrap: "break-word"

Ref: QA: wrap long string without any blank

Demo

<Typography
  variant="h1"
  component="h2"
  align="center"
  style={{ wordWrap: "break-word" }}
>
  123 456 789 qwertyuiopasdfghjklzxcvbnmdfsafasfasfadfaf
</Typography>
