title: How do you disable "Swipe down to close" on the Modal component in React Native?
body: <p>I'm using the core <a href="https://facebook.github.io/react-native/docs/modal.html" rel="noreferrer">React Native Modal component</a>. Within the modal content I have a <code>Done</code> button. </p>
  
  <p>Pressing <code>Done</code>is the only way we want users to close the modal. But the Modal component allows swiping down from the top of the screen to close.</p>
  
  <p>How do you turn off "swipe to close"?</p>
