title: How do I listen to keyboard input in React Native
body: <p>I have a Honeywell Scanner that outputs text when scanning bar codes.
  I can use it as a "keyboard" for text inputs, which comes in very handy because I don't have to interface anything.
  But it has the downside of having to focus an input and thus displaying the virtual keyboard of the mobile device, which is unacceptable for the project I'm working on.</p>
  
  <p>Is there any way to get the value scanned without having to focus an input? I believe that listening for the keyPress events or the likes of it would be the way to go, storing the value inputted in a variable elsewhere than the textInput.</p>
  
  <p>If there's a better way of achieving this, I'm all ears!</p>
