title: vuetify child component property
body: <p>I want to wrap a vuetify component into another one and select which property is configured from the parent. </p>
  
  <p>I.e.Child component myToolbar</p>
  
  <pre><code>&lt;template&gt;
     &lt;v-toolbar app fixed&gt;&lt;/..&gt;
  &lt;/templare&gt;
  </code></pre>
  
  <p>in parent I would like to configure the fact that the child uses a black, flat attribute like:</p>
  
  <pre><code>&lt;my-toolbar black flat&gt;...&lt;/my-toolbar&gt;
  </code></pre>
  
  <p>How can I know from my child component which attributes where passed by the parent and enable them on the v-toolbar ?</p>
  
  <p>I seem to be stuck with the fact that those are booleans so dark=true does not seem to work.</p>
  
  <p>Any help would be welcome,</p>
  
  <p>Thanks</p>
  
  <p>Pat</p>
