title: Delaying display of page until [ngClass] has been evaluated
body: <p><strong>Background</strong> I have a header component having [ngClass] attached to top div.</p>
  
  <p><strong>Question</strong> Is it possible to delay displaying of page until [ngClass] has been evaluated? We used to have ng-cloak in AngularJs. Do we have something similar in Angular?</p>
  
  <p><strong>Why I need it</strong> This would help me in avoiding the undesirable flicker effect.</p>
  
  <p><strong>Header template</strong></p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;div [ngClass]="{'no-hero': headerType === 400, 'restaurant-page': headerType === 200, 'restaurant-list': headerType === 300}"
      class="top-section"&gt;
    &lt;div class="top-section-bg"&gt;
    &lt;/div&gt;
   // Code removed for brevity
  &lt;/div&gt;</code></pre>
  </div>
  </div>
  </p>
