title: component forwarding call to child
body: <p>I'm new ot react native and am having a hard time with the idea of not using inheritance, but rather composition.</p>
  
  <p>My scenario: I'm creating a component (focusedTextInput) which shows one InputText. My component simply adds functionality to change the style of the TextInput on focus.</p>
  
  <p>I'm using FocusedTextInput in another component which contains five focusedTextInput and I configure those to only have one character at a time and to auto-skip to the next FocusedTextInput when the character is entered (using the focus() method).</p>
  
  <p>Where I'm running into issues is the my FocusedTextInput does not have a focus method (and I don't want to expose the TextInput).</p>
  
  <p>So do I need to surface all the method that might be used from TextInput on FocusedTextInput or is there a better way?</p>
