title: Font family in Text Input React native
body: <p>I am trying to implement a text input, where the font family is Zila Slab Bold, But the font family only works for the place holder of the text input, It doesn't work for the inputted text instead it shows the default android text, but when I use Zila Slab Medium it works for both the placeholder and Inputted text, Please what may  I be doing wrong, I'm using RN 0.55.0</p>
  
  <p>This is what I want to get</p>
