react-navigation - navigating back to previous screen after opening app from deep link not working -


i'm trying implement deep linking in react native app i'm having trouble maintaining expected back-button behavior when closing out of view nested in stack navigator. root navigator stacknavigator has tabnavigator path 'customer'. inside tab navigator there 4 tabs, 1 of has path 'order-now' screen being stacknavigator. ordernow stack has 3 child screens this:

const ordernowtab = stacknavigator({   root: { screen: storesscreen, path: 'show-stores' },   menu: { screen: storeitemsscreen, path: 'show-stores/:store_id'},   item: { screen: itemdetailsscreen, path: 'show-stores/:store_id/:item_id'} });

when follow deep linking guides running adb shell start -w -a android.intent.action.view -d "mychat://mychat/customer/order-now/show-stores/some_store_id/some_item_id" com.sampleapp taken item details screen expected, when press arrow button within navigation header, app appears close screen , land on exact copy of 1 closed (item details). difference new screen doesn't have arrow button within header, giving me impression it's @ root of stack navigator when shouldn't (pressing should have brought me storeitemsscreen).

why happen , how can storeitemsscreen show after pressing button (either navigation header or physical android button) instead?

my package.json file's dependencies section looks this:

"dependencies": {     "react": "16.0.0-alpha.12",     "react-native": "0.48.1",     "react-navigation": "^1.0.0-beta.11"   },

and here file's i'm using:

// src/app.js import react 'react'; import { appregistry, platform } 'react-native'; import { stacknavigator } 'react-navigation';  const sampleapp = stacknavigator({   home: { screen: require('./homescreen') },   customertabbar: { screen: require('./customer/customernavigator'), path: 'customer' },   chat: { screen: require('./customer/chatscreen'), path: 'chat/:user' }, }, {mode: "modal", headermode: "none"});  const prefix = platform.os == 'android' ? 'mychat://mychat/' : 'mychat://'  const mainapp = () => <sampleapp uriprefix={prefix} />  appregistry.registercomponent('sampleapp', () => mainapp);

src/homescreen.js:

import react 'react' import {text, button, view} 'react-native'  class homescreen extends react.component {   static navigationoptions = {     title: 'welcome',   };   render() {     const { navigate } = this.props.navigation;     return (       <view>         <text>hello, chat app!</text>         <button           onpress={() => navigate('chat', { user: 'lucy' })}           title="chat lucy"         />       </view>     );   } }  module.exports = homescreen

customernavigator.js:

import { tabnavigator } 'react-navigation';  const customernavigator = tabnavigator({   ordernow: { screen: require('./ordernowtab'), path: 'order-now' },   futureorders: { screen: require('./futureordersscreen'), path: 'future-order' },   bag: { screen: require('./bagscreen'), path: 'bag-tab' },   yourorders: { screen: require('./yourordersscreen'), path: 'your-orders' },   account: { screen: require('./accountscreen'), path: 'your-account' }, },{   tabbaroptions: {     activetintcolor: '#000',   } })  module.exports = customernavigator

ordernowtab.js:

import react 'react'; import {text} 'react-native'; import { stacknavigator } 'react-navigation';  class storesscreen extends react.component {   static navigationoptions = ({ navigation }) => ({     title: `stores`,   });   render() {     return (       <text>list of stores</text>     )   } }  class storeitemsscreen extends react.component {   static navigationoptions = ({ navigation }) => ({     title: `store items`,   });   render() {     const { params } = this.props.navigation.state;     return (       <text>store items screen store id {params.store_id}</text>     )   } }  class itemdetailsscreen extends react.component {   static navigationoptions = ({navigation}) => ({     title: 'item details'   })   render() {     const { params } = this.props.navigation.state     return (       <text>item details screen item id {params.item_id} , store id {params.store_id}</text>     )   } }  const ordernowtab = stacknavigator({   root: { screen: storesscreen, path: 'show-stores' },   menu: { screen: storeitemsscreen, path: 'show-stores/:store_id'},   item: { screen: itemdetailsscreen, path: 'show-stores/:store_id/:item_id'} });  module.exports = ordernowtab

and here gif of looks like: enter image description here
