title: React-Native-Maps how to draw polylines
body: <p>I've started using <a href="https://github.com/airbnb/react-native-maps" rel="nofollow">https://github.com/airbnb/react-native-maps</a> and having no luck drawing polylines from an array of array coordinates on the map.</p>
  
  <p>I am not sure if I'm passing in the array of coordinates correctly.</p>
  
  <p>this is how I am rendering the polyline:</p>
  
  <pre><code>      {this.state.polylines.map(polyline =&gt; (
          &lt;MapView.Polyline
            key={polyline.id}
            coordinates={polyline.coordinates}
            strokeColor="#000"
            fillColor="rgba(255,0,0,0.5)"
            strokeWidth={1}/&gt;
        ))}
  </code></pre>
  
  <p><strong>polyline.coordinates</strong> looks like: </p>
  
  <pre><code>      [[lat,lng],[lat,lng],[lat,lng]]
  </code></pre>
  
  <p>Thank you for any help/advice :D</p>
