title: Different behaviours between platforms in react-native-keyboard-aware-scroll-view
body: <p>I have a problem with the library <a href="https://github.com/APSL/react-native-keyboard-aware-scroll-view" rel="nofollow noreferrer">react-native-keyboard-aware-scroll-view</a>.</p>
  
  <p>I have configured in Android <code>windowSoftInputMode="adjustPan"</code> and I'm using <code>enableOnAndroid</code> and with the same code I have different behaviours when I use a fixed element at the bottom, outside the <code>KeyboardAwareScrollView</code>.</p>
  
  <p>The problem is that in iOS I have an extra padding with the same heigth that the outside component.</p>
  
  <p>This is my test code:</p>
  
  <pre><code>import React from 'react';
  import {
    View,
    Text,
    TextInput,
  } from 'react-native';
  import {KeyboardAwareScrollView} from 'react-native-keyboard-aware-scroll-view'
  
  const App = () =&gt; {
    return (
      &lt;&gt;
      &lt;KeyboardAwareScrollView enableOnAndroid extraHeight={0}&gt;
          &lt;View style={{height: 600}}/&gt;
          &lt;TextInput 
          placeholder='hey' 
          style={{
            width: '100%',
            borderWidth: 1,
            height: 60
          }} /&gt;
      &lt;/KeyboardAwareScrollView&gt;
      &lt;View style={{backgroundColor: '#f0f', paddingVertical: 20, width: '100%'}}&gt;
        &lt;Text&gt;Hello, I'm bottom View&lt;/Text&gt;
      &lt;/View&gt;
      &lt;/&gt;
    );
  };
  
  export default App;
  </code></pre>
  
  <p>And this is the behaviour:</p>
  
  <p><strong>iOS</strong> </p>
  
  <p>As you can see, height padding between TextInput and Keyboard is bigger than in Android and is exactly equal than bottom View height.</p>

  <p><strong>Android</strong></p>

  <p>How can I do to solve this? Thanks in advance :)</p>
