<Navigator.Config />

The Config component is a a component that is used to configure the current screen and navigation bar. The component itself does not result in any UI being rendered in the current react view hierarchy, but instead is used as a declarative interface for the screen.

The Config component can be rendered at any point in the react view hierarchy, and multiple instances of the component can be rendered in the same hierarchy, with the props of each getting merged together with the preference being given to the instances in the order that they mount.

Usage

import React from 'react';
import Navigator from 'native-navigation';

export default class Screen extends React.Component {
  render() {
    const {
      children,
      title,
    } = this.props;

    return (
      <Navigator.Config
        title={title}
        backgroundColor="#F7F7F7"
        elevation={4}
        onBackPress={() => console.log('onBackPress')}
        onLeftPress={() => console.log('onLeftPress')}
        onRightPress={(index) => console.log('onRightPress', index)}
        onAppear={() => console.log('onAppear')}
