title: Flatlist is making my app very slow
body: <p>I need to render about 1000 rows with <code>Flatlist</code>. Unfortunately, after rendering a few ones without problems, my app begins to be very slow and freezing so that it become totally impossible to manipulate. I'm looking for a solution to use instead of <code>Flatlist</code> which showed its limit. I need a module that can handle hundreds of rows without any problem.</p>
  
  <p>Can someone provide me some advices ?</p>
  
  <pre><code>   &lt;FlatList
  
     data={this.state.data}
      onEndReached={this.props.onEndReached}
      initialNumToRender={5}
      keyExtractor={(item, index) =&gt; item.objectID}
      renderItem={this._renderItem}
    /&gt; 
  </code></pre>
