title: How to add helper text in date field in material UI?
body: <p>This is my component definition:</p>
  <pre><code>&lt;DateField
        name={formElement.name}
        type=&quot;date&quot;
        label={formElement.name}
        onChange={(date) =&gt; formik.setFieldValue(formElement.name, date)}
        value={formik.values[formElement.name] || null}
        onBlur={blurHandler}
        className={classes.flexGrow}
        // defaultValue={dataMatchHandler(formElement.name) || ''}
        minDate={doj}
        maxDate={Date('1/1/2023')}
        error={formik.touched[formElement.name] &amp;&amp; Boolean(formik.errors[formElement.name])}
        helperText={formik.touched[formElement.name] &amp;&amp; formik.errors[formElement.name]}
  /&gt;
  </code></pre>
  <p>Now when the value changes to below <code>minDate</code> error is triggered fine, but I also want to display a helper text, how do I do that?</p>
