Can not access to firebase.database.ServerValue.TIMESTAMP in React-Native
<p>After upgraded to Firebase <em>3.2.0</em> (react-native <em>0.30</em>), I'm trying to set a <code>TIMESTAMP</code> as described in the docs:</p>

<pre><code>  import Firebase from 'firebase'
    ...
  let config = {
    apiKey:  `${ Config.firebase.apiKey }`,
    authDomain: `${ Config.firebase.authDomain }`,
    databaseURL: `${ Config.firebase.databaseURL }`,
    storageBucket: `${ Config.firebase.storageBucket }`
  }

  const firebase = Firebase.initializeApp(config)
  const created_at = firebase.database.ServerValue.TIMESTAMP
</code></pre>

<p>then I get</p>

<blockquote>
  <p>created_at = undefined</p>
</blockquote>

<p>when debugging with Chrome' Developer Tools, <code>firebase.database</code> is a function without any <code>ServerValue</code> in it.</p>

<p>Any idea ?</p>
