I don't think Material UI provides progress bar as shown in your image above.
However, you can make use of React Bootstrap package and get things done.
Here is the link - https://react-bootstrap.github.io/components/progress/

You could display this.state.completed which shows the percentage value of the progress and the just add some style to it. Of course, you'll have to concatenate a % at the end if you want to be more explicit because it is nothing but a number.
