Move state outside NavigationRootContainer, so you can combine navigator state into your redux reducer.

NavigationRootContainer modified props

• navState navigation state in redux store
• onNavigation navigation handler

NavigationReducer wrapper

import { NavigationReducer } from 'navigation-rfc';

const initialState = {routes: ['first page'], index: 0};

export default function navigation(state = initialState, action = {}) {
    return NavigationReducer(state, action);
}
