undefined is not an object (evaluating 'navigation.navigate') when trying to navigate to a file that will open camera on the phone

I'm trying to navigate to my page "CameraPage.js" but I'm getting this error "undefined is not an object (evaluating 'navigation.navigate')". Can anybody see the problem? This ismy first question here so please tell me if I can be more specific.
Here's my App.js:
import { StyleSheet, Text, View, TouchableOpacity, Pressable } from 'react-native';
import React, {useEffect, useState} from "react";
import { FontAwesome } from '#expo/vector-icons';
import { useNavigation } from '#react-navigation/native';
export default function App({ navigation }) {
return (
<View style={styles.container}>
<View style={styles.buttonContainer}>
<TouchableOpacity onPress ={() => navigation.navigate('CameraFunction')}>
<FontAwesome name="camera" size={100} color="#FFB6C1" />
</TouchableOpacity>
<Pressable>
<FontAwesome name="photo" size={100} color="#FFB6C1" />
</Pressable>
</View>
</View>
);
}
const styles = StyleSheet.create({
container: {
flex: 1,
justifyContent: 'center',
alignItems: 'center',
backgroundColor: '#FFDBE9'
},
buttonContainer: {
backgroundColor: 'transparent',
justifyContent: 'space-between',
},
});
Here is my CameraPage.js file:
import {StyleSheet, Text, View, TouchableOpacity} from 'react-native';
import {Camera, CameraType} from 'expo-camera';
import {useEffect, useState} from "react";
export default function CameraPage() {
const [hasPermission, setHasPermission] = useState(null);
const [type, setType] = useState(CameraType.back);
useEffect(() => {
(async () => {
const {status} = await Camera.requestCameraPermissionsAsync();
setHasPermission(status === 'granted');
})();
}, []);
if (hasPermission === null) {
return <View/>;
}
if (hasPermission === false) {
return <Text>No access to camera</Text>;
}
return (
<View style={styles.container}>
<Camera style={styles.camera} type={type}>
<View style={styles.buttonContainer}>
<TouchableOpacity
style={styles.button}
onPress={() => {
setType(type === CameraType.back ? CameraType.front : CameraType.back);
}}>
<Text style={styles.text}> Flip </Text>
</TouchableOpacity>
</View>
</Camera>
</View>
);
}
const styles = StyleSheet.create({
container: {
flex: 1,
},
camera: {
flex: 1,
},
buttonContainer: {
flex: 1,
backgroundColor: 'transparent',
flexDirection: 'row',
margin: 20,
},
button: {
flex: 0.1,
alignSelf: 'flex-end',
alignItems: 'center',
},
text: {
fontSize: 18,
color: 'white',
},
});
Here is my navigation file:
import React from 'react';
import {createStackNavigator} from '#react-navigation/stack';
import {NavigationContainer} from '#react-navigation/native';
import CameraPage from "../Camera/CameraPage";
const Routes = createStackNavigator();
export default function Navigator() {
return (
<NavigationContainer>
<Routes.Navigator>
<Routes.Screen
name="CameraFunction"
component={CameraPage}
/>
</Routes.Navigator>
</NavigationContainer>
);
}

Your navigation container must be wrapped around the root of your application or otherwise the navigation object will not be passed to the components that you have defined as screens.
The following fixes your issue.
export default const App = () => {
return (
<NavigationContainer>
<Routes.Navigator>
<Routes.Screen name="Home" component={HomeScreen} />
<Routes.Screen
name="CameraFunction"
component={CameraPage}
/>
</Routes.Navigator>
</NavigationContainer>
);
}
Your HomeScreen contains the old code from App, but now you can access the navigation object since we have defined HomeScreen as a screen inside the navigator. It will be passed to that screen by the navigation framework. Notice as well that HomeScreen is the initial screen of your application.
export default function HomeScreen({ navigation }) {
return (
<View style={styles.container}>
<View style={styles.buttonContainer}>
<TouchableOpacity onPress ={() => navigation.navigate('CameraFunction')}>
<FontAwesome name="camera" size={100} color="#FFB6C1" />
</TouchableOpacity>
<Pressable>
<FontAwesome name="photo" size={100} color="#FFB6C1" />
</Pressable>
</View>
</View>
);
}
const styles = StyleSheet.create({
container: {
flex: 1,
justifyContent: 'center',
alignItems: 'center',
backgroundColor: '#FFDBE9'
},
buttonContainer: {
backgroundColor: 'transparent',
justifyContent: 'space-between',
},
});
Notice, that you need to navigate back to the HomeScreen once you have navigated to the CameraPage. You can use the navigation object in the CameraPage as well and trigger navigation.goBack to achieve this effect.

You just use #react-navigation/native-stack in place of #react-navigation/stack in App.js file then it will working perfect ,
import * as React from 'react';
import {NavigationContainer} from '#react-navigation/native';
import {createNativeStackNavigator} from '#react-navigation/native-stack';
import Home from './TopTabBar/Home';
import 'react-native-gesture-handler';
const Stack = createNativeStackNavigator();
function App() {
return (
<NavigationContainer>
<Stack.Navigator>
<Stack.Screen name="Home" component={Home} />
</Stack.Navigator>
</NavigationContainer>
);
}
export default App;

is there a way to remove title on each screens in expo?

i am a beginner in react-native, i follow tutorials on youtube to make projects. i am trying to make an expo ui-app, but each screens has a title on the top like this:
There is the word Explore above the screen, and each other screens has the corresponding title above it aswell. Is there a way to remove this? because i followed tutorials from youtube but they didnt have this title.
Here is the Explore.js file:
import { StyleSheet, Text, View, SafeAreaView, TextInput, Platform, StatusBar } from 'react-native';
import React, { Component } from 'react';
import { Ionicons } from '#expo/vector-icons';
class Explore extends Component {
componentWillMount() {
this.startHeaderHeight = 80
if(Platform.OS == 'android')
{
this.startHeaderHeight = 100 + StatusBar.currentHeight
}
}
render() {
return (
<SafeAreaView style={{ flex: 1 }}>
<View style={{ flex: 1 }}>
<View style={{ height: this.startHeaderHeight, backgroundColor: 'white', borderBottomWidth: 1, borderBottomColor: '#dddddd' }}>
<View style={{flexDirection: 'row', padding: 10, backgroundColor: 'white', marginHorizontal: 20, shadowOffset:{width:0,height:0}, shadowColor: 'black', shadowOpacity: 0.2, elevation: 1, marginTop: Platform.OS == 'android' ? 30 : 20 }}>
<Ionicons name="ios-search" size={20} color="black" />
<TextInput
underlineColorAndroid="transparent"
placeholder='Try Indonesia'
placeholderTextColor="grey"
style={{ flex: 1, fontWeight: '700', backgroundColor: 'white', marginLeft: 10 }}
/>
</View>
</View>
</View>
</SafeAreaView>
);
}
}
export default Explore;
const styles = StyleSheet.create({
container: {
flex: 1,
backgroundColor: '#fff',
alignItems: 'center',
justifyContent: 'center',
},
});
and here is my app.js file:
import React from 'react';
import { StyleSheet, Text, View, Image } from 'react-native';
import { NavigationContainer } from '#react-navigation/native';
import { createBottomTabNavigator } from '#react-navigation/bottom-tabs';
import { Ionicons } from '#expo/vector-icons';
import { FontAwesome5 } from '#expo/vector-icons';
import Explore from './screens/Explore';
import Saved from './screens/Saved';
import Trips from './screens/Trips';
import Inbox from './screens/Inbox';
const Tab = createBottomTabNavigator();
export default function BottomTabs() {
return (
<NavigationContainer>
<..... CODE OF THE BOTTOM TAB NAVIGATOR IN HERE .....>
</NavigationContainer>
);
}
const styles = StyleSheet.create({
container: {
flex: 1,
backgroundColor: '#fff',
alignItems: 'center',
justifyContent: 'center',
},
});

David Scholz's solution is good for individual screens. If you want to disable the header on all child screens of a navigator, you can use
screenOptions={{ headerShown: false }}
as a prop on the Tab.Navigator, or any top-level navigator.

You could hide the header using the options={{headerShown: false}} prop as follows.
const Tab = createBottomTabNavigator();
export default function BottomTabs() {
return (
<NavigationContainer>
<Tab.Navigator>
<Tab.Screen name="Test" options={{
headerShown: false
}}/>
</Tab.Navigator>
</NavigationContainer>
);
}

Navigation, not working from Pulled functions

I will try to explain this as best I can, I'm still new and have a hard time understanding the terminology.
I am working on a react native project. I have created two files. One Header.js and one footer.js.
I have successfully pulled them in to my Home Screen. However the buttons, inside footer.js, no longer fires. I get; undefined is not an object (evaluating 'navigation.navigate') for the error.
How do I bring back the functionality?
Any help is very appreciated. Here is my project to help;
App.js
import React from 'react';
import TabNavigator from "./assets/component/TabNavigator";
import {StackNavigation} from "./assets/component/StackNavigation";
export default function App() {
return (
<StackNavigation/>
);
}
StackNavigation.js;
import React from 'react';
import { HomeScreen} from "../Screens/HomeScreen";
import LayoutProps from "../Screens/Layout Props";
import SampleViewProps from "../Screens/SampleViewProps";
import {NavigationContainer} from "#react-navigation/native";
import {createNativeStackNavigator} from "#react-navigation/native-stack";
// import ShareExample from "./assets/component/SBShare";
const Stack = createNativeStackNavigator();
export function StackNavigation() {
return (
<NavigationContainer>
<Stack.Navigator initialRouteName="Home">
<Stack.Screen name="Home" component={HomeScreen}/>
<Stack.Screen name="Layout Props" component={LayoutProps} />
<Stack.Screen name="View Props" component={SampleViewProps} />
</Stack.Navigator>
</NavigationContainer>
);
}
HomeScreen.js;
import React from 'react';
import {Button, View, SafeAreaView, StyleSheet} from 'react-native';
import HeaderSB from "../component/SBHeader";
import FooterSB from "../component/SBFooter";
// import ShareExample from "./assets/component/SBShare";
export function HomeScreen({navigation}) {
const receiveValue = (value) => {
console.log("value received from B", value)
}
return (
<>
<SafeAreaView style={styles.container}>
<View style={styles.headerContainer}>
<HeaderSB receiveValue={receiveValue}>
</HeaderSB>
</View>
<View style={styles.mainContent}>
<View style={styles.buttonBox}>
<Button onPress={() => navigation.navigate('Layout Props')} title="Layout Props"/>
<Button onPress={() => navigation.navigate('View Props')} title="View Style Props"/>
</View>
</View>
<View styles={styles.footerContainer}>
<FooterSB receiveValue={receiveValue}>
</FooterSB>
</View>
</SafeAreaView>
</>
);
}
const styles = StyleSheet.create({
container: {
flex: 1,
justifyContent: "space-between",
},
headerContainer: {
},
mainContent: {
},
buttonBox: {}
,
footerContainer: {
},
});
Footer.js;
import * as React from "react";
import {StyleSheet, TouchableOpacity, View} from "react-native";
import {AntDesign, Feather} from "#expo/vector-icons";
import {StackNavigation} from "./StackNavigation";
const FooterSB = ({navigation}) => {
return (
<>
{/* Bottom App Navigation */}
<View style={footerStyle.navCon}>
<View style={footerStyle.navBar}>
{/* Home Button */}
<TouchableOpacity style={footerStyle.home} onPress={() =>
navigation.navigate('Home')}
>
{/* Icon */}
<AntDesign name="home" size={50} color="white"/>
</TouchableOpacity>
{/* Navigation Divider */}
<View style={footerStyle.navDivider}/>
{/* Setting Button */}
<TouchableOpacity style={footerStyle.settings} onPress={() =>
navigation.navigate('Layout Props')}
>
{/* Icon */}
<Feather name="settings" size={50} color="white"/>
</TouchableOpacity>
</View>
</View>
</>
);
}
const footerStyle = StyleSheet.create({
navCon: {
flex: 1,
marginTop: 20,
alignItems: "center",
justifyContent: "flex-end"
},
navBar: {
flexDirection: "row",
justifyContent: "space-evenly",
alignItems: "center",
backgroundColor: "#808080",
width: 500,
height: 50,
},
home: {
// paddingHorizontal: 55,
},
navDivider: {
backgroundColor: "#FFF",
width: 4,
height: 50,
},
settings: {
// marginRight: 107,
// paddingHorizontal: 55,
},
});
export default FooterSB;

If you want navigation as default prop you should add it as <Stack.Screen> but as FooterSB is custom and individual component it doesn't get wrapped with navigation prop automatically.
You need to pass navigation as prop to that so change below
<FooterSB receiveValue={receiveValue}>
</FooterSB>
to
<FooterSB receiveValue={receiveValue} navigation={navigation}>
</FooterSB>
Same way you can pass navigation to header too.

React Native NavigationContainer not displaying anything

I'm having an issue using React Native with React Navigator where I'm not seeing a navigation menu at all. I'm using the following code:

export default Login;
This is what I'm seeing on the Android emulator:
I'm looking to have a navigation menu available to the user and also to have the Home page be the default landing page for the application. How do I do this? What am I doing wrong?

Your Home component must have {flex: 1} on it's container. Specifically in your case you've got 'styles.home' but you don't have that value included in your stylesheet.
And remove the {flex: 1} from the navigator.

Rendering another screen in react-native app

I'm experiencing trouble navigating between pages in my react native app. When I attempt to use the button, I get the following error message: TypeError: undefined is not an object (evaluating '_this.props.navigation') I have created my app using numerous js files, and id like to navigate between them using buttons. My App.js file renders to the WelcomeScreen from initializing.
import 'react-native-gesture-handler';
import React from 'react';
import { NavigationContainer } from '#react-navigation/native';
import RecipesList from "cakeapp/app/screens/RecipesList.js";
import { ImageBackground, StyleSheet, View, Text, Button, navigation } from "react-native";
function WelcomeScreen(props) {
return (
<NavigationContainer>
<ImageBackground
style={styles.background}
source={require('cakeapp/app/assets/MainPage.png')}
>
<Text style={styles.text}>MyCakeRecipes</Text>
<View style={styles.homeButton}>
<Button
title="Recipes"
onPress={() => this.props.navigation.navigate('RecipesList')}
/>
</View>
</ImageBackground>
</NavigationContainer>
);
}
const styles = StyleSheet.create({
background: {
flex:1,
justifyContent: "flex-end",
},
text: {
fontSize: 30,
fontWeight: "bold",
color: "white",
textAlign: "center",
bottom: 500,
},
homeButton: {
width: '100%',
height: 40,
backgroundColor: '#5f7f8a'
}
})
export default WelcomeScreen;
import React from 'react';
import { Image, ScrollView, View, Text, } from 'react-native';
const imageDis = {
width: 150,
height: 150
//flex:1,
//justifyContent: "flex-end"
};
const Recipes = () => (
<ScrollView style={{backgroundColor: '#5f7f8a'}}>
<Text style={{ fontSize: 20 }}>Chocolate Cake</Text>
<Image source={require('cakeapp/app/assets/Choc.png')} style={imageDis} />
<Text style={{ fontSize: 20 }}>Chocolate cupcake</Text>
<Image source={require('cakeapp/app/assets/ChocCu.png')} style={imageDis} />
<Text style={{ fontSize: 20 }}>Lemon Cake</Text>
<Image source={require('cakeapp/app/assets/Lemon.png')} style={imageDis} />
<Text style={{ fontSize: 20 }}>Lemom meringue</Text>
<Image source={require('cakeapp/app/assets/LemonM.png')} style={imageDis} />
<Text style={{ fontSize: 20 }}>Chocolate Berry</Text>
<Image source={require('cakeapp/app/assets/ChcoBerry.png')} style={imageDis} />
</ScrollView>
);
export default Recipes

As far as I know, < NavigationContainer> is used in app.js file to define the screens you want to navigate to. And you have to pass navigation as a prop to the component.
Your app.js file should look something like this
const Stack = createStackNavigator();
const App = () => {
return (
<NavigationContainer>
<Stack.Navigator>
<Stack.Screen
name="Welcome"
component={WelcomeScreen}
/>
<Stack.Screen
name="Recipes"
component={RecipesList} />
</Stack.Navigator>
</NavigationContainer>
);
};
And your welcomeScreen like this:
const WelcomeScreen = ({ navigation }) => {
return (
<Button
title="RecipesList"
onPress={() =>
navigation.navigate('RecipesList')
}
/>
);
};
Let me know if it doesnt work
