Angular2 visual cues for required fields
<p>I have the following markup</p>
<h2>.html</h2>
<pre><code>  &lt;div
      class = &quot;mdl-textfield mdl-js-textfield mdl-textfield--floating-label form-group&quot;&gt;
    &lt;input
        required
        type = &quot;text&quot;
        pattern = &quot;{{regex}}&quot;
        [(ngModel)] = &quot;name.first&quot;
        ngControl = &quot;first&quot;
        #first = &quot;ngForm&quot;
        class = &quot;mdl-textfield__input form-control&quot;
        id = &quot;first&quot;&gt;
    &lt;label
        class = &quot;mdl-textfield__label&quot;
        for = &quot;first&quot;&gt;First&lt;/label&gt;
    &lt;span *ngIf = &quot;showErrorMsg()&quot;
          class =
              &quot;mdl-textfield__error&quot;&gt;{{msg}}&lt;/span&gt;
  &lt;/div&gt;
</code></pre>
<p>Does angular2 (and angular2-dart) have any built-in visual-cues to indicate to the user that a field is required?</p>
<p>Thanks</p>
