title: Accessibility focus event in React Native
body: <p>I'm programming a react native game app for blind kids to help them with maths. There is a game in which they have to count how many animals are in the screen; when an animal is pressed it emits a sound.</p>
  
  <p>In react native there is the <code>onPress</code> property of <code>&lt;TouchableWithouFeedback /&gt;</code> which allows me to play the sound, but when it comes to visually impaired users I have to announce that there is an animal instead of just playing the sound.</p>
  
  <p>How can I know if a certain <code>View</code> is focused by the screen reader and call a function to do that?</p>
