This is for now, for my personal use only, things might not be correctly explained here. For the official docs please check: https://github.com/exponentjs/ex-navigation/blob/master/README.md
On every screen you can use the built-in navigation bar, you can add a title, left button, right button or change navigation bar’s style. All you need to do is pass appropriate params to navigationBar in the route configuration:
import React, { Component } from 'react';
