title: How to set the custom font family globally at once and use throughout the react-native app without calling in every 'Text' component?
body: <p>As per this <a href="https://stackoverflow.com/questions/29310828/use-custom-font-in-react-native">stack overflow</a> solution custom font can be used by calling it in each and every <code>Text</code> component. But we may happen to miss the same font family when we have some thousands of <code>Text</code> components in our App. Then we lose consistency in case of font family.</p>
  
  <p>Hence, Is there any way to use custom font family by not calling in every <code>Text</code> component?</p>
