createBottomTabNavigator: hide just one tab from the tabBar - javascript

I'm using createBottomTabNavigator and listing all my pages there in a file called Navigator.js. The problem is that i have one page called 'AboutScreen' and i don't want to show in the TabNavigator. I just need this 'AboutScreen' there to use
onPress={() => this.props.navigation.navigate('AboutScreen')}
on another screen called SettingScreen.js. When i use that function above with the AboutScreen instanced in Navigator.js the navigation works but 'AboutScreen' appears in the bottom tab, that's what i don't want. Is there a way to hide only this page 'AboutScreen' that appears in my bottom tab? My codes below:
//This is Navigator.js
const Tab = createBottomTabNavigator({
Home: {screen: HomeScreen,
navigationOptions: {
tabBarLabel: 'Home',
tabBarIcon: ({tintColor, activeTintColor}) => (
<Icon name="home" size={19} color={tintColor} />
)
},},
Catalog: {screen: CatalogScreen,
navigationOptions: {
tabBarLabel: 'Catalog',
tabBarIcon: ({tintColor, activeTintColor}) => (
<Icon name="local-library" size={19} color={tintColor} />
)
},},
MyLibrary: {screen: MyLibraryScreen,
navigationOptions: {
tabBarLabel: 'My Library',
tabBarIcon: ({tintColor, activeTintColor}) => (
<Icon name="star" size={19} color={tintColor} />
)
},},
Setting: {screen: SettingScreen,
navigationOptions: {
tabBarLabel: 'Setting',
tabBarIcon: ({tintColor, activeTintColor}) => (
<Icon name="settings" size={19} color={tintColor} />
)
},},
AboutScreen: {screen: AboutScreen,
navigationOptions: {
tabBarLabel: 'AboutScreen',
tabBarIcon: ({tintColor, activeTintColor}) => (
<Icon name="home" size={19} color={tintColor} />
)
},},
},{
tabBarPosition: 'bottom',
swipeEnabled: true,
showIcon: true,
tabBarOptions:{
showIcon: true,
showLabel: true,
activeTintColor: '#FEFEFE',
inactiveTintColor: '#614B70',
activeBackgroundColor: '#614B70',
inactiveBackgroundColor: '#FEFEFE',
}
});
//And this is the SettingScreen.js where i want to use the 'AboutScreen'
import React from 'react';
import { Platform, StatusBar, StyleSheet, View, Text, TouchableOpacity, ScrollView, Button, Image, TouchableHighlight } from 'react-native';
import { Icon } from 'react-native-elements';
export default class SettingScreen extends React.Component {
render() {
return(
<ScrollView style={styles.container}>
<TouchableOpacity style={styles.itemContainerTouchable}
onPress={() => this.navigateScreen('Home')}>
<View style={styles.itemContainer}>
<Icon
name="settings"
color={'#614B70'}
style={styles.itemIcon}
/>
<Text style={styles.itemText}>General</Text>
</View>
<View
style={{height: 1, width: '100%', backgroundColor: '#614B70'}}
/>
</TouchableOpacity>
</ScrollView>
);
}
navigateScreen(object) {
this.props.navigation.navigate(object);
}
}
//styles are irrelevant

You have to create a customBottomTabNavigator.
The one I'm using right now is this:
import React from 'react'
import { BottomTabBar } from 'react-navigation-tabs'
import { View, TouchableWithoutFeedback, Dimensions } from 'react-native'
import { StyleSheet } from 'react-native';
var { height } = Dimensions.get("window")
const HiddenView = () => <View style={{ display: 'none' }} />
const TouchableWithoutFeedbackWrapper = ({
onPress,
onLongPress,
testID,
accessibilityLabel,
...props
}) => {
return (
<TouchableWithoutFeedback
onPress={onPress}
onLongPress={onLongPress}
testID={testID}
hitSlop={{
left: 15,
right: 15,
top: 5,
bottom: 5,
}}
accessibilityLabel={accessibilityLabel}
>
<View {...props} />
</TouchableWithoutFeedback>
)
}
export default TabBarComponent = props => {
return <BottomTabBar
{...props}
style={styles.bottomBarStyle}
getButtonComponent={({ route }) => {
if (route.key === "ScreenToHideKey" )
return HiddenView
else return TouchableWithoutFeedbackWrapper
}}
/>
}
const styles = StyleSheet.create({
bottomBarStyle: {
height: (height * 10.625) / 100 //your header height (10.625 is the %)
}
})
Then where you use your createBottomTabNavigator:
{
tabBarPosition: 'bottom',
swipeEnabled: true,
showIcon: true,
tabBarComponent: (props) => (<BottomBar {...props} ></BottomBar>) //remember to import it
tabBarOptions:{
showIcon: true,
showLabel: true,
activeTintColor: '#FEFEFE',
inactiveTintColor: '#614B70',
activeBackgroundColor: '#614B70',
inactiveBackgroundColor: '#FEFEFE',
}

You can use a StackNavigator nested inside of your BottomTabBarNavigator, in the nested StackNavigator you put the SettingsScreen first and then the AboutScreen. Then you remove from your tab bar the AboutScreen. and everything should work as expected

My tab navigation header button doesnt working. How can I fix it?

I'm trying to learn react native and I have a problem. Here I use tab navigation and I want to add an image in my headers right side and when the users touch that image I want use navigator, but it doesn't work.
import React, { useEffect, useState } from 'react'
import { View, StyleSheet, Image, TouchableOpacity } from 'react-native'
import { NavigationContainer } from '#react-navigation/native';
import { createBottomTabNavigator } from '#react-navigation/bottom-tabs'
import { createStackNavigator } from '#react-navigation/stack';
const TabNavigation = ({ navigation }) => {
return (
enter code here
<Tab.Screen
name="Home"
component={HomeScreen}
options={{
headerTitle: () => (<Image source={require('../Images/Floody.png')} />),
headerStyle: {
height: 100
},
headerTitleAlign: 'center',
headerRight: () => (
<TouchableOpacity>
<Image source={require('../Images/profile.jpg')} />
</TouchableOpacity>
),
tabBarIcon: ({ focused }) => focused ? <HomeImageColorfull /> : <HomeImageBlack />
}} />
The navigation object is passed by the navigation framework to the options of the screen. Hence, you can implement a onPress function for your TouchableOpacity of your headerRight component and use the navigation object from the options.
<Tab.Screen
name="Home"
component={HomeScreen}
options={({navigation}) => ({
headerTitle: () => (<Image source={require('../Images/Floody.png')} />),
headerStyle: {
height: 100
},
headerTitleAlign: 'center',
headerRight: () => (
<TouchableOpacity onPress={() => navigation.navigate("SomeScreenToNavigateTo")}>
<Image source={require('../Images/profile.jpg')} />
</TouchableOpacity>
),
tabBarIcon: ({ focused }) => focused ? <HomeImageColorfull /> : <HomeImageBlack />
})} />

How to navigate to nested screen in react-native

I am trying to navigate to another screen with in my album component when the user click
on a album but I keep getting this error
The action 'NAVIGATE' with payload {"name":"AlbumScreen"} was not handled by any navigator.
below is my code and my try
navigation->Album->index.tsx
import React from 'react';

<Text style={styles.text}>{props.album.artistsHeadline}</Text>
</View>
</TouchableWithoutFeedback>

export default AlbumComponent;
here is my AlbumScreen.tsx also this is the screen I want to user to move to once they click on the Album

Why is React Native App.js navigation undefined in App.js?

export default function App ({navigation})
There is a function that starts with and contains <Stack.Navigator>.
But when I want to use the navigation feature and use "navigation.navigate ('Lead') in onPress
TypeError: undefined is not an object evaluating react navigation
I get an error. My English is not very good. Please help me on this topic. Now I'm adding the sample codes to you.
import * as React from 'react';
import { StyleSheet, AsyncStorage, Alert, View, Image, TouchableOpacity } from 'react-native';
import { NavigationContainer } from '#react-navigation/native';
import { createStackNavigator } from '#react-navigation/stack';
import { createBottomTabNavigator } from '#react-navigation/bottom-tabs';
import { ApplicationProvider, Layout, Input, Button, Text, Spinner, IconRegistry, Icon } from '#ui-kitten/components';
import { EvaIconsPack } from '#ui-kitten/eva-icons';
import * as eva from '#eva-design/eva';
import LinkingConfiguration from './navigation/LinkingConfiguration';
import * as axios from 'axios';
import Base64 from './components/Base64';
import LeadScreen from './screens/LeadScreen';
import AddLeadScreen from './screens/AddLeadScreen';
import TabBarIcon from './components/TabBarIcon';
import HomeScreen from './screens/HomeScreen';
import CampaignsScreen from './screens/CampaignsScreen';
import MenuScreen from './screens/MenuScreen';
const Stack = createStackNavigator();
export default function App({ navigation }) {
const logout = async () => {
await AsyncStorage.removeItem('token');
dispatch({ type: 'SIGN_OUT' });
};
return (
<>
<IconRegistry icons={EvaIconsPack} />
<ApplicationProvider {...eva} theme={eva.light}>
<Layout style={styles.container}>
<AuthContext.Provider value={authContext}>
<NavigationContainer linking={LinkingConfiguration}>
<Stack.Navigator>
{state.isLoading ? (
// We haven't finished checking for the token yet
<Stack.Screen name="Splash" component={SplashScreen} options={{ headerShown: false }} />
) : state.token == null ? (
// No token found, user isn't signed in
<>
<Stack.Screen name="Login" component={LoginScreen} options={{ title: 'Oturum Açın' }} />
</>
) : (
// User is signed in
<>
<Stack.Screen name="User" component={UserScreen} options={{
headerStyle: { backgroundColor: '#e8a200' },
headerTintColor: 'white',
headerTitleStyle: { color: '#fff' },
headerRight: () => (
<TouchableOpacity activeOpacity={0.4} underlayColor='transparent' onPress={() => logout() } style={{ marginRight: 12 }}>
<Icon
style={styles.icon}
fill='#FFFFFF'
name='power-outline'
/>
</TouchableOpacity>
)
}} />
<Stack.Screen name="Lead" component={LeadScreen} options={{
title: 'Müşteri Adayları',
headerStyle: { backgroundColor: '#e8a200' },
headerTintColor: 'white',
headerTitleStyle: { fontWeight: 'bold', color: '#fff' },
headerRight: () => (
<TouchableOpacity activeOpacity={0.4} underlayColor='transparent' onPress={ () => console.log(navigation) } style={{ marginRight: 12 }}>
<Icon
style={styles.icon}
fill='#FFFFFF'
name='plus-outline'
/>
</TouchableOpacity>
)}} />
<Stack.Screen name="AddLead" component={AddLeadScreen} options={{ title: 'Müşteri Adayı Ekle' }} />
</>
)}
</Stack.Navigator>
</NavigationContainer>
</AuthContext.Provider>
</Layout>
</ApplicationProvider>
</>
);
}
You can pass the navigation or rout prop into options in the stack.screen like this
options={({navigation})=>({
'Your code here'
})}
I have edited it with your code for you.
<Stack.Screen name="Lead" component={LeadScreen}
options={({ navigation }) => ({
title: 'Müşteri Adayları',
headerStyle: { backgroundColor: '#e8a200' },
headerTintColor: 'white',
headerTitleStyle: { fontWeight: 'bold', color: '#fff' },
headerRight: () => (
<TouchableOpacity activeOpacity={0.4}
underlayColor='transparent' onPress={() =>
console.log(navigation)} style={{ marginRight: 12 }}>
<Icon
style={styles.icon}
fill='#FFFFFF'
name='plus-outline'
/>
</TouchableOpacity>
)
})} />
First, I think the navigation here is unnecessary, you can remove it.
export default function App({ navigation }) {
In your screen components, ie. UserScreen, you can use navigation like so
function UserScreen({navigation}) {
// ...some codes
navigation.navigate('WHERE_TO_GO');
// ...some other codes
}
You could also use navigation without passing it to the props.
First you need to import useNavigation
import { useNavigation } from '#'react-navigation/native'
And then, in your component
function UserScreen() {
const nav = useNavigation();
// ...some codes
nav.navigate('WHERE_TO_GO');
// ...some other codes
}
You could get more details here https://reactnavigation.org/docs/use-navigation/
For the onPress function of Lead screen,
<Stack.Screen name="Lead" component={LeadScreen} options={({ navigation }) => ({
title: 'Müşteri Adayları',
headerStyle: { backgroundColor: '#e8a200' },
headerTintColor: 'white',
headerTitleStyle: { fontWeight: 'bold', color: '#fff' },
headerRight: () => (
<TouchableOpacity activeOpacity={0.4} underlayColor='transparent' onPress={ () => navigation.navigate('WHERE_TO_GO') } style={{ marginRight: 12 }}>
<Icon
style={styles.icon}
fill='#FFFFFF'
name='plus-outline'
/>
</TouchableOpacity>
)})} />
You should use useLinkProps to solve this issue:
import { useLinkProps } from '#react-navigation/stack';
And this is an example on how to write code which uses it:
const LinkButton = ({ to, action, children, ...rest }) => {
const { onPress, ...props } = useLinkProps({ to, action });
I have tried everything but this worked for me.
Make a function in your app.js and pass props then access using props.navigation like below.
function CustomDrawerContent**(props)** {
.....
logOut = () => {
AsyncStorage.clear();
**props.navigation.navigate("Login");**
};
.....
}

I did find this question in a few other places, but I'm still unable to resolve the issue with any of the help given. I got most of the code so far from this article -
https://medium.com/#austinhale/building-a-mobile-app-in-10-days-with-react-native-c2a7a524c6b4
Some of the APIs were outdated, but most of them I was able to replace with the new version - One of the APIs i changed that might be notable in regards to this question is stackNavigator -> createStackNavigator
My code is as follows:

},
rowText: {

}
});
You can change your onPress functionality in AppItem.js like below. Use arrow function inside your onPress onPress={() => this._onViewApp()}. Because Arrow function does not create the context "this". It refers to the context of the component that it was wrapped in. For lexical this refer this Arrow function vs function declaration / expressions: Are they equivalent / exchangeable?
import { Icon } from 'react-native-elements';
import { ViewApp } from './ViewApp';
export default class AppItem extends Component {
_onViewApp(){
let id = this.props.id;
this.props.navigation.navigate('ViewApp', { id: id })
}
render() {
return (
<TouchableOpacity onPress={() => this._onViewApp()}>
<View style={styles.rowContainer}>
<Image source={{ uri: this.props.thumbnail }}
style={styles.thumbnail}
resizeMode="contain" />
<View style={styles.rowText}>
<Text style={styles.title} numberOfLines={2} ellipsizeMode={'tail'}>
{this.props.title}
</Text>
<Text style={styles.description} numberOfLines={2} ellipsizeMode={'tail'}>
{this.props.description}
</Text>
</View>
</View>
</TouchableOpacity>
);
}
}
I wanted to follow up for everyone who's having the same issue. I just included withNavigation from 'react-native-navigation'; and exported at the end of the component like so export default withNavigation(AppItem);.

React Navigation Undefined is not a object

I am trying to navigate from login screen to home screen and below is the error I am getting.
