Steps to Reproduce / Code Snippets / Screenshots
Create RN app, install required modules (redux, react-redux, react-native-navigation, react-vector-icons) and run code on Android device.
Add relevant code, App.js and component that causes the error. I tried running Navigation.push with this.props.componentId but when I press the button there is no response
App.js
import { Navigation } from 'react-native-navigation';
import { Provider } from 'react-redux';
import AuthScreen from './src/screens/Auth/Auth';
import SharePlaceScreen from './src/screens/SharePlace/SharePlace';
import FindPlaceScreen from './src/screens/FindPlace/FindPlace';
import PlaceDetailScreen from './src/screens/PlaceDetail/PlaceDetail';
import configureStore from './src/store/configureStore';
const store = configureStore();
// Register Screens
Navigation.registerComponentWithRedux("awesome-places.AuthScreen", () => AuthScreen, Provider, store);
Navigation.registerComponentWithRedux("awesome-places.SharePlaceScreen", () => SharePlaceScreen, Provider, store);
Navigation.registerComponentWithRedux("awesome-places.FindPlaceScreen", () => FindPlaceScreen, Provider, store);
Navigation.registerComponent("awesome-places.PlaceDetailScreen", () => PlaceDetailScreen);
// Start an App
Navigation.events().registerAppLaunchedListener(() => {
Navigation.setRoot({
root: {
component: {
name: 'awesome-places.AuthScreen'
}
}
});
});
FindPlace.js
import React, { Component } from 'react';
import { View, Text } from 'react-native';
import { connect } from 'react-redux';
import { Navigation } from 'react-native-navigation';
import PlaceList from '../../components/PlaceList/PlaceList';
class FindPlaceScreen extends Component {
Navigation.push(this, {
component: {
name: 'awesome-places.AuthScreen',
}
})
}
render () {
return(
<View>
<PlaceList places={this.props.places} onItemSelected={this.itemSelectedHandler} />
</View>
);
}
}
const mapStateToProps = state => {
return {
places: state.places.places
}
}
export default connect(mapStateToProps)(FindPlaceScreen);
Environment
React Native Navigation version: 2.17.0
React Native version: 0.59.4
Platform(s) (iOS, Android, or both?): Android
Device info (Simulator/Device? OS version? Debug/Release?): Android 7.1.2, Debug

I noticed you're pushing the screen with this instead of an explicit componentId.
When calling Navigation.push, the first argument needs to be a componentId. See the docs for reference.
Also, this might not be a problem, but registerComponentWithRedux is deprecated and you should register the screen with the new api

null is not an object (evaluating 'this.nativeCommandsModule.push')

I am using WIX-React-Native-Navigation and while pushing a component in the stack I am getting this error.
Error
One thing to say, I am using Viro-React ARScene Navigation (Scene Navigation) in WIX-React-Native-Navigation.
Here's my code
index.js
import { AppRegistry } from 'react-native';
var OpenDoor = require('./app/base')
import Stack from './app/navigation';
import { Navigation } from "react-native-navigation";
AppRegistry.registerComponent('ViroSample', () => OpenDoor);
Navigation.events().registerAppLaunchedListener(() => {
Navigation.setRoot({
root: {
stack: Stack
}
});
});
navigation.js
import { Navigation } from "react-native-navigation";
import Base from './base';
import Menu from './components/Menu/menu';
Navigation.registerComponent('Base', () => Base);
Navigation.registerComponent('Menu', () => Menu);
const Stack = {
children: [{
component: {
name: 'Base'
},
}
]
};
export default Stack;
base.js
import React, {Component} from 'react';
import {
Alert,
View
} from 'react-native';
import {ViroARSceneNavigator} from 'react-viro';
import { Navigation } from 'react-native-navigation';
import APIKeys from './index';
import Camera from './components/Camera/camera';
import MenuButton from './components/Menu/menu_button';
class Base extends Component {
constructor(props) {
super(props);
this.navigateScreen = this.navigateScreen.bind(this);
}
navigateScreen(location) {
Navigation.push(this.props.componentId, {
component: {
name: location
}
});
}
render() {
return(
<View style={styles.container}>
<ViroARSceneNavigator
initialScene = {{
scene: Camera
}}
apiKey = {APIKeys.ViroReact}
style = {styles.ar_scene}
/>
<MenuButton navigation={this.navigateScreen}/>
</View>
);
}
};
const styles = {
container: {
flex: 1
}
};
export default Base;
module.exports = Base;
Correct me, If I am wrong somewhere.
What I am doing is, creating an application where users can decorate home virtually with the help of Augmented Reality. The mobile app is created on React-Native while the library used for augmented reality is Viro-React.
So, When I want to navigate from One Screen to another, then while pushing component in the stack I am getting this error.
Thanks.

undefined is not an object (evaluating '_reactNativeNavigation.default.push')

I just updated RNN to version 2 and I'm stuck with my first push
I get an error :
undefined is not an object (evaluating '_reactNativeNavigation.default.push')
other answers on stack overflow didn't help me much so far
I guess my issue is related to this.props.componentId but I couldn't find any help in the official doc as well.
or perhaps it's coming from a wrong call to the stack since I never use the id property set in App.js
I'm also wondering if I have to provide an id manually for each screen or, as it is said in the doc it will be done automatically by RNN
if someone can guide me, I'm a bit lost -_-
my code :
App.js
import { Navigation } from 'react-native-navigation';
import { Provider } from 'react-redux';
import LandingScreen from './src/screens/Landing/Landing';
import AuthScreen from './src/screens/Auth/Auth';
import configureStore from './src/store/configureStore';
import strings from './src/global/strings';
const store = configureStore();
// Landing
Navigation.registerComponentWithRedux(strings.screens.screenLanding, () => LandingScreen, Provider, store);
// Auth
Navigation.registerComponentWithRedux(strings.screens.screenAuth, () => AuthScreen, Provider, store);
// Start App
Navigation.events().registerAppLaunchedListener(() => {
Navigation.setRoot({
root: {
stack:{
id:"appStack",
children: [
{
component: {
name: strings.screens.screenLanding,
options: {
topBar:{
title:{
text:"Welcome"
}
}
}
}
}
]
},
}
});
});
Landing.js
import React, { Component } from 'react';
import { View, Button } from 'react-native';
import Navigation from 'react-native-navigation';
import strings from '../../global/strings';
class Landing extends Component {
goToScreen = (screenName) => {
Navigation.push(this.props.componentId, {
component: {
name: screenName
}
})
}
render() {
return (
<View>
<Button
title="Connexion"
onPress={() => this.goToScreen(strings.screens.screenAuth.toString())}
/>
</View>
)
}
}
export default Landing;
as indicated by jinshin1013 in RNN issue tracker In Landing.js,
I should have import Navigation like this :
import { Navigation } from 'react-native-navigation

How to fix "Requested prototype of a value that is not an object" when use react-native-navigation

im using react-native and react-native-navigation but when I run the project, occur this error "Requested prototype of a value that is not an object".
i did not to use redux
App.js :
import {Navigation} from 'react-native-navigation';
import {HomeComponent} from './src/home';
Navigation.registerComponent("navigation.playground.HomeComponent", () => HomeComponent);
Navigation.events().registerAppLaunchedListener(() => {
Navigation.setRoot({
root: {
component: {
name: 'navigation.playground.HomeComponent'
}
}
});
});
index.js :
import {Navigation} from "react-native-navigation";
import {App} from './App';
Navigation.registerComponent(`navigation.playground.HomeComponent`, () => App);
Navigation.events().registerAppLaunchedListener(() => {
Navigation.setRoot({
root: {
component: {
name: "navigation.playground.HomeComponent"
}
}
});
});
home.js :
import React, {Component} from 'react';
import { Text, View} from 'react-native';
class HomeComponent extends Component{
render() {
return (
<View>
<Text>This is Home</Text>
</View>
);
}
}
export default HomeComponent;
and then end,
result:
You are having this problem when your Gradle is not compatible with your version of react-native
https://wix.github.io/react-native-navigation/#/docs/Installing
7 and 8 section is very important and the solution of the problem
If you read the documentation carefully, wouldn't happen!
Although the implementation of react-native-navigation is really complicated!
at the end use Gradle 4.4 instead of 4.6 for react-native57

Navigation: project.testscreen registration result is 'undefined'

I've just installed react-native-navigation using the installation guides provided on https://wix.github.io/react-native-navigation/#/installation-ios and the usage guide https://wix.github.io/react-native-navigation/#/usage.
I've followed these and checked out multiple example apps, but I cannot figure out why my screens won't register.
The error I receive is: console.error: "Navigation: project.testscreen registration result is 'undefined'".
The registerScreens is called and the registration is completed, but it seems like the registration results to undefined.
index.js
import App from './src/app'
const app = new App();
app.js
import { Navigation } from 'react-native-navigation';
import { registerScreens } from './screens';
registerScreens();
Navigation.startTabBasedApp({
tabs: [{
label: 'Test',
screen: 'project.testscreen',
title: 'Test',
}]
});
screens.js
import { Navigation } from 'react-native-navigation'
import { TestScreen } from './components/testScreen'
export function registerScreens() {
Navigation.registerComponent('project.testscreen', () => TestScreen)
}
testScreen.js
import React, { Component } from 'react';
import { Text, View } from 'react-native';
class TestScreen extends Component {
render() {
return (
<View>
<Text>Hi</Text>
</View>
)
}
}
export default TestScreen
react-native: 0.55.4
react-native-navigation: latest (1.1.479)
change
import { TestScreen } from './testScreen'
to
import TestScreen from './testScreen'
Because TestScreen exports as default

Simple react native app(with react-native-navigation) crash after splash screen

I'm trying to use react-native-navigation as navigation system in my react-native. I've wrote a very simple app for test it, but this app crashes(without giving me any error or info) after the splash screen.
my index.ios.js:
/* eslint-disable no-unused-vars */
import App from './src/app';
my app.ios.js:
import {
Platform
} from 'react-native';
import {Navigation} from 'react-native-navigation';
import { registerScreens } from './screens';
registerScreens(); // this is where you register all of your app's screens
// this will start our app
Navigation.startTabBasedApp({
tabs: [{
label: 'One',
screen: 'AwesomeProject.Home', // this is a registered name for a screen
icon: require('../img/one.png'),
selectedIcon: require('../img/one_selected.png'), // iOS only
title: 'Screen One'
}]
});
my screens.js
import { Navigation } from 'react-native-navigation';
import Home from './containers/Home';
import About from './containers/About';
// register all screens of the app (including internal ones)
export function registerScreens() {
Navigation.registerComponent('AwesomeProject.Home', () => Home);
Navigation.registerComponent('AwesomeProject.About', () => About);
}
my Home.js:
import React, { Component } from 'react';
import { Text } from 'react-native';
class Home extends Component {
render() {
return (
<Text>Home!</Text>
);
}
}
export default Home;
my About.js:
import React, { Component } from 'react';
import { Text } from 'react-native';
class About extends Component {
render() {
return (
<Text>About!</Text>
);
}
}
export default About;
You can see a full gist here: https://gist.github.com/inchr/d0184f4ae91abd6036a2fa61725744c9
I've done very test on how loads the tabs in startTabBasedApp() and I've tried to load only a screen too.
Any idea on the reason of the crash/close after the splash screen ?
Thanks.
Ok the problem was that after I've run: react-native link
I've forgot to edit the AppDelete.m file as explained here:
