      &lt;/View&gt;
  )
  
  export default () =&gt; (
      &lt;Router&gt;
          &lt;Scene hideNavBar&gt;
  
              &lt;Scene key="tabbar" tabs tabBarStyle={{backgroundColor: '#000'}}&gt;
  
                  &lt;Scene key="list" title="Ahlo" component={List} hideNavBar icon={TabBar} /&gt;
  
                  &lt;Scene key="search" component={search} hideNavBar icon={TabBar} /&gt;
  
                  &lt;Scene key="account" component={account} hideNavBar icon={TabBar} /&gt;
