title: React-Native onKeyPress Android while having empty string
body: <p>I'm having an issue something.</p>
  
  <p>I have have an app in which I have an Input that creates Chip/Tag. Basically, it's a textInput with a listing underneath and be clicking on a item in the list, it remove the text and add a chip juste before it. </p>
  
  <p>What I'm trying to do is to be able to delete the last Chip by using backspace in the TextInput ONLY WHEN there are no value to it. </p>
  
  <p>So it would be a simple way to delete the chip without having to remove them by clicking on a little x on them. (Basically how the Tags on Stack Overflow works)</p>
  
  <p>I know that since RN-0.53, they added support to the <code>onKeyPress</code> props of the TextInput. However, it does not trigger when making a backspace on an empty value (since the value technically didn't change)</p>
  
  <p>Anyone would have an idea to catch the Backspace action when the textInput is empty? Or possibly a workaround?</p>
  
  <p>Thanks!</p>
