I have the same error with TabNavigator.
I also have executed the official react-navigation example (https://github.com/react-community/react-navigation/blob/master/examples/NavigationPlayground/js/SimpleTabs.js) with no success (same error).
My guess is that this is a bug of latest versions of Expo/React Native.
What versions are you using?
I'm using:
"dependencies": {
"expo": "^22.0.2",
"react": "16.0.0-beta.5",
"react-native": "^0.49.5",
"react-navigation": "^1.0.0-beta.20"
}
Confirmed: ejecting from Create React Native App solves the problem.
So, it seems to be a bug on Create React Native App or Expo.

What I want to do
I wanna make tabs in bottom using createBottomTabNavigator.
Home and My Page tabs.
Error that I'm facing
Error: Creating a navigator doesn't take an argument. Maybe you are trying to use React Navigation 4 API with React Navigation 5?
ps
I'm using
"#react-navigation/native": "^5.2.3",
"#react-navigation/stack": "^5.2.8",
"#react-navigation/bottom-tabs": "^5.0.6",
I would appreciate it if you could give me any advices.
const MyTabs = () => {
return(
<Tab.Navigator>
<Tab.Screen name="Home" component={HomeScreen} />
<Tab.Screen name="Mypage" component={MypageScreen} />
</Tab.Navigator>);
}
Can you try this? I think I missed the return statement
Add the bottomTabNavigator inside a StackNavigator. In future, if you are adding more screens you can add it to the stack
import React from 'react';
import {NavigationContainer} from '#react-navigation/native';
import {createStackNavigator} from '#react-navigation/stack';
import { createBottomTabNavigator } from 'react-navigation-tabs';
import { Icon } from 'react-native-elements';
import HomeScreen from 'app/src/screens/home/Index';
import MypageScreen from 'app/src/screens/mypage/Index';
const Stack = createStackNavigator();
const Tab = createBottomTabNavigator();
const MyTabs = () => {
<Tab.Navigator>
<Tab.Screen name="Home" component={HomeScreen} />
<Tab.Screen name="Mypage" component={MypageScreen} />
</Tab.Navigator>
}
const AuthStack = () => (
<Stack.Navigator>
<Stack.Screen name="Tabs" component={MyTabs} />
</Stack.Navigator>
);
const AuthenticationNavigator = () => (
<NavigationContainer>
<AuthStack />
</NavigationContainer>
);
export default AuthenticationNavigator;

Using FontAwesome in a tabbar with React Native

I am new to react native and am trying to create a tabbar using createBottomTabNavigator. I would like each tab to have its own icon.
I have followed the following tutorial which uses FontAwesome to display the tab icon.
Tutorial
When I run my app in the iso simulator the tabs display but the icons don't.
Here is my code
import { createStackNavigator } from 'react-navigation-stack';
import { createAppContainer } from 'react-navigation';
import { createBottomTabNavigator } from 'react-navigation-tabs';
import Icon from "react-native-vector-icons/FontAwesome5";
import HomeScreen from './HomeScreen';
import SecondActivity from './second';
const TabNavigator = createBottomTabNavigator({
Home: { screen: HomeScreen,
defaultNavigationOptions: {
tabBarIcon: ({tintColor}) =>
<Icon name="home" size={25} color={tintColor} />
}
},
Events: { screen: SecondActivity,
defaultNavigationOptions: {
tabBarIcon: ({tintColor}) =>
<Icon name="chart-bar" size={25} color={tintColor} />
}
}
}
);
const MyStack = createStackNavigator({
Tabs: {
screen: TabNavigator
},
Home: {
screen: HomeScreen
},
Events: {
screen: SecondActivity
}
},
{
initialRouteName: 'Tabs',
}
);
export default createAppContainer(MyStack);
How do I get the icons to display?
I have a solution for you that is a bit different that what you did in there .. so
const config = Platform.select({
web: { headerMode: "screen" },
default: {}
})
const HomeStack = createStackNavigator(
{
Home: HomeScreen
},
config
)
HomeStack.navigationOptions = {
tabBarIcon: ({ focused }) => (
<TabBarIcon
focused={focused}
name={Platform.OS === "ios" ? "ios-calendar" : "md-calendar"}
/>
)
}
HomeStack.path = ""
and them you can do like this in createBottomTabNavigator
const tabNavigator = createBottomTabNavigator(
{
HomeStack,
},
{
activeColor: '#000'
}
// You can import Ionicons from #expo/vector-icons if you use Expo or
// react-native-vector-icons/Ionicons otherwise.
import Ionicons from 'react-native-vector-icons/Ionicons';
import { createAppContainer } from 'react-navigation';
import { createBottomTabNavigator } from 'react-navigation-tabs';
export default createBottomTabNavigator(
{
Home: HomeScreen,
Settings: SettingsScreen,
},
{
defaultNavigationOptions: ({ navigation }) => ({
tabBarIcon: ({ focused, horizontal, tintColor }) => {
const { routeName } = navigation.state;
let IconComponent = Ionicons;
let iconName;
if (routeName === 'Home') {
iconName = focused
? 'ios-information-circle'
: 'ios-information-circle-outline';
// Sometimes we want to add badges to some icons.
// You can check the implementation below.
IconComponent = HomeIconWithBadge;
} else if (routeName === 'Settings') {
iconName = focused ? 'ios-list-box' : 'ios-list';
}
// You can return any component that you like here!
return <IconComponent name={iconName} size={25} color={tintColor} />;
},
}),
tabBarOptions: {
activeTintColor: 'tomato',
inactiveTintColor: 'gray',
},
}
);

Uncaught Error: undefined is not an object (evaluating 'Y.props.navigation') touchableHandlePress#[native code]

I'm adding in the react-navigation header a drawerMenuButton to open the Drawer Menu.
The icon appears normally but when pressed returns the error quoted.

const AppDrawerContainer = createAppContainer(DrawerNavigator);
export default AppDrawerContainer;
It is important to note that for screens belonging to const DrawerNavigator = createDrawerNavigator I am using the same code above to render drawerMenuButton and it is working normally, the error occurs only on const screens HomeNavigator = createStackNavigator.
Change your code like this
onPress={() => navigation.toggleDrawer()}>

How to force stackNavigator to target MainScreen?

I have implemented a StackNavigator and a DrawerNavigator, in my DrawerNavigator in the first option I am calling StackNavigator. The problem is that when I'm browsing Stack screens I wanted to go back to the main screen through Drawer but this doesn't happen because Stack stores the last screen the user was on.
I have tried using some Navigation Prop but I am not sure where to insert this code or even which of the commands to use on the stack.

Can you try reset , change method navLink
import { StackActions, NavigationActions } from 'react-navigation';
navLink(nav, text) {
return (
<TouchableOpacity
style={{ height: 50 }}
onPress={() => {
const resetAction = StackActions.reset({
index: 0,
actions: [NavigationActions.navigate({ routeName: nav })]
});
this.props.navigation.dispatch(resetAction);
}}
>
<Text style={styles.link}>{text}</Text>
</TouchableOpacity>
);
}
Try using this.props.navigation.push('your_pagename') this will push new item to the stack. It means when using push componentDidMount() method call again

Why doesn't the nested stack navigation work in react native?

I'm a beginner programmer and I'm trying to created a nested navigator in react native. The stack navigator on the Home screen works but the stack navigator on the MyEvents Screen does not. I use the tabs to navigate between Home and MyEvents and within the those pages I want to use a stack navigator to get to other pages. Please help! (also please let me know if I am being unclear)
This is Router.js
import React from 'react';
import {StackNavigator, TabNavigator} from 'react-navigation';
import InputScreen from './InputPage';
import HomeScreen from './Home';
import DetailsScreen from './Details';
import MyEventsScreen from './MyEvents';
import EditScreen from './EditPage';
import MapScreen from './Map';
const BottomNavigation = require('react-native-bottom-navigation');
export const Tabs = TabNavigator({
Home: {screen: HomeScreen},
EventMap: {screen: MapScreen},
Input: {screen: InputScreen},
MyEvents:{screen: MyEventsScreen},
},{
tabBarOptions: {
activeTintColors: '#e91e63',
//swipeEnabled: true,
}
});
export const EventsStack = StackNavigator({
Home: {
screen: Tabs,
},
Details: {
screen: DetailsScreen,
navigationOptions: {
