title: react native animated flatlist item after item
body: <p>I'm looking a way to make animated flatlist item after item. when one item finish his animation so next item(from the flatlist) will be on the screen</p>
  
  <pre><code>class AnimatedFlatList extends React.PureComponent {
      state = {selected: (new Map(): Map&lt;string, boolean&gt;)};
      let data = {[
          {"first_name":"ltorrejon0@si.edu"},
          {"first_name":"ichadbourne1@icq.com"},
          {"first_name":"ascorthorne2@mediafire.com"},
          {"first_name":"jlathwood3@xing.com"},
          {"first_name":"molkowicz4@ftc.gov"},
          {"first_name":"motridge5@tiny.cc"},
          {"first_name":"rcess6@hostgator.com"},
          {"first_name":"mmaundrell7@php.net"},
          {"first_name":"ufairburne8@instagram.com"},
          {"first_name":"pangel9@biglobe.ne.jp"}]
      };
  
      _keyExtractor = (item, index) =&gt; item.id;
  
      _onPressItem = (id: string) =&gt; {
          // updater functions are preferred for transactional updates
          this.setState((state) =&gt; {
              // copy the map rather than modifying state.
              const selected = new Map(state.selected);
              selected.set(id, !selected.get(id)); // toggle
              return {selected};
          });
      };
  
      _renderItem = (item) =&gt; (
          &lt;View style={Styles.viewItem}}&gt;
              &lt;Text style={Styles.textItem&gt;{item.text}&lt;/Text&gt;
          &lt;/View&gt;
      );
  
      render() {  
          return (
              &lt;FlatList
                  data={data}
                  extraData={this.state}
                  keyExtractor={this._keyExtractor}
                  renderItem={this._renderItem}
              /&gt;
          );
      }
  }
  </code></pre>
  
  <p>When I did <code>animatedView</code> into the <code>renderItem</code> it runs all together and it not what I'm looking for.</p>
  
  <p>Kind of <a href="https://www.youtube.com/watch?time_continue=3&amp;v=q_jh0dl8iH0" rel="noreferrer">this way</a> (but without press on the button, it will load automatically)</p>
