title: React Native Snap Carousel: Invariant Violation: inputRange must be monotonically increasing NaN,NaN,NaN
body: <p>I'm very new to React Native and I'm trying to use this component:
  <a href="https://github.com/archriss/react-native-snap-carousel" rel="noreferrer">https://github.com/archriss/react-native-snap-carousel</a></p>
  
  <p>I tried using that code they provided in the usage portion to create the simplest working version:</p>
  
  <pre><code>    return (
          &lt;Carousel
            ref={(c) =&gt; { this._carousel = c; }}
            data={this.state.entries} // this seems to be the problem
            renderItem={this._renderItem}
            sliderWidth='100%'
            itemWidth='80%'
          /&gt;
      );
  </code></pre>
  
  <p>Where "entries" is an array. This results in the following error:</p>
  
  <pre><code>Invariant Violation: inputRange must be monotonically increasing NaN,NaN,NaN
  </code></pre>
  
  <p>Edit: Here's the _renderItem method</p>
  
  <pre><code>_renderItem ({item, index}) {
      return (
          &lt;View style={styles.slide}&gt;
              &lt;Text style={styles.title}&gt;{ item.title }&lt;/Text&gt;
          &lt;/View&gt;
      );
    }
  </code></pre>
