title: Can an annotation be overriden in Dart?
body: <p>Update: As a clarification by "get rid" of the annotation I mean suppressing the warnings the analyzer throws without changing anything in the analyzer itself</p>
  
  <p>I'm extending a class with an annotation and I want to override the parent class annotation, more particularly, get it rid of it. Is it possible to do so?</p>
  
  <p>For example:</p>
  
  <pre class="lang-dart prettyprint-override"><code>@immutable
  class A {}
  
  /// get rid of @immutable annotation
  class MutableA extends A {}
  </code></pre>
