title: Why is Flow/Nuclide showing me a warning "not covered by Flow" in my React-Native component?
body: <p>I'm starting to use flow and have a simple component :</p>
  
  <pre class="lang-jsx prettyprint-override"><code>// @flow
  import React, { Component } from 'react';
  import {
    Text,
    ScrollView
  } from 'react-native';
  
  const Conversations = (props: { messages: string }) =&gt; (
    &lt;ScrollView&gt;
      &lt;Text&gt;{props.messages}&lt;/Text&gt;
    &lt;/ScrollView&gt;
  );
  
  export default Conversations;
  </code></pre>
  
  <p>In Nuclide, I see this warning "Warning, type coverage, not covered by Flow". It's pointing at line 9, where I use <code>&lt;ScrollView&gt;</code>.</p>

  <p>Why is that / What does it mean / How can I fix it ?</p>
