title: React Native FlatList with object
body: <p>I want to render object with React Native's FlatiList but this component doesn't return the expected result.
  My dictionary is like this:</p>
  
  <pre><code>Object {
    "Lisa.Sky": Object {
      "name": "Lisa",
      "surname": "Sky",
      "age": 21,
      "sex": female
    },  
    "Thomas.Prat": Object {
      "name": "Thomas",
      "surname": "Prat",
      "age": 33,
      "sex": male
    },  
    "Paul.Sing": Object {
      "name": "Paul",
      "surname": "Sing",
      "age": 88,
      "sex": male
    },
    "Andrew.Brown": Object {
      "name": "Andrew",
      "surname": "Brown",
      "age": 23,
      "sex": male
    },
  }
  </code></pre>
  
  <p>I have implemented a FlatList like this, but I have white screen</p>
  
  <pre><code>   &lt;View&gt;
         &lt;ScrollView&gt;
             &lt;FlatList
                  data={this.props.nameList}
                  renderItem={({item}) =&gt; 
                      &lt;View key={item.name + "." + item.surname}&gt;  
                          &lt;Text style={styles.viewDetail}&gt;{item.name}&lt;/Text&gt;
                          &lt;Text style={styles.viewDetail}&gt;{item.surname}&lt;/Text&gt;
                          &lt;Text style={styles.viewDetail}&gt;{item.age}&lt;/Text&gt;
                          &lt;Text style={styles.viewDetail}&gt;{item.sex}&lt;/Text&gt;
                      &lt;/View&gt;
                  }
                  keyExtractor={(index) =&gt; index.toString()}
             /&gt;
         &lt;/ScrollView&gt;
     &lt;/View&gt;
  </code></pre>
  
  <p>Thanks</p>
