title: How to use ever() with Flutter getx variable in GetxController if I didn't add .obs
body: <p>I am using Flutter getx package.</p>
  <p>I know how to use &quot;ever&quot; with (.obs) variable like this</p>
  <pre><code>class CountController extends GetxController {
      final count = 0.obs;
              
      @override
      void onInit() {
          ever(count1, (_) =&gt; print(&quot;$_ has been changed&quot;));
          super.onInit();
      }
      
  }
  </code></pre>
  <p>But how to use &quot;ever()&quot; or triggering specific callbacks when variable change if the variable doesn't have (.obs) because I am using GetBuilder (not : Obx  or GetX) in my view</p>
