title: Render multiple marker in react-native-maps
body: <p>Hye, Im new in react native and want to ask how do I render multiple markers in maps.</p>
  
  <p>This is my code</p>
  
  <p>inside class:-</p>
  
  <pre><code>constructor(props) {
  super(props);
  
    this.state = {
     coordinate: ([{
       latitude: 3.148561,
       longitude: 101.652778,
       title: 'hello'
     },
     {
       latitude: 3.149771,
       longitude: 101.655449,
       title: 'hello'
     }
    ]),
   };
  </code></pre>
  
  <p>}</p>
  
  <p>inside render:-</p>
  
  <pre><code>&lt;MapView
          style={styles.map}
          showsUserLocation={true}
          followUserLocation={true}
          zoomEnabled={true}
          //annotations={markers}
        &gt;  
              &lt;MapView.Marker
                coordinate={this.state.coordinate}
                title={this.state.coordinate.title}
              /&gt;
        &lt;/MapView&gt;
  </code></pre>
  
  <p>I want to render this two marker inside maps and I have no idea how to make loop yet in react native to render this. I already try what in documentation but still not working.</p>
  
  <p>Thank you in advance :)</p>
