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

});
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.

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';

const Stack = createNativeStackNavigator();
function App() {
return (
<NavigationContainer>
<Stack.Navigator>
<Stack.Screen name="Home" component={Home} />
</Stack.Navigator>
</NavigationContainer>
);
}
export default App;
I'm having a problem getting my React Navigation to actually transition screens. I've used it successfully before and I cannot figure out what my problem is this time. I click my button and no transition happens. I think it might be a problem with the inline onPress not running....does it have to be in Main Button? Or does the inline code on App.js override anything in MainButton.js.
Also...NarScreen is the screen I'm trying to get to.

Inside your MainButton.js file, you are not handling onPress event. Add it to touchable opacity.
const MainButton = props => {
return <TouchableOpacity onPress={props.onPress}>
<View style={styles.button}>
<Text style={styles.buttonText}>{props.children}</Text>
</View>
</TouchableOpacity>
}
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.

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

I don't understand why the "onPress" isn't working here . I am unable to even click on it . it is just like a text with no response or change in opacity too . The navigation isn't working either.
#nandita you are using onPress on Text tag. onPress event only works on TouchableOpacity or TouchableHightlight
try doing this.
<TouchableOpacity onPress={pressHandler}>
<Text style={{backgroundColor:'white',
fontSize:30,
borderWidth:2,
borderRadius:4,
marginTop: 5,
marginLeft:10,
marginRight:10,
fontWeight:'bold',
textAlign:'center',
padding:2,
}}
>Login</Text>
<TouchableOpacity>
Today i spend 6 hours trying to figure this out, this is kind of my last resort.
I want to switch screens with react navigate. It works when all the screens are in the same file. but when i seperate them into multiple files (1 file for every screen) it gives me the error 'undefined is not an object (evaluating '_this.props.navigation.navigate')
i have tried a lot of things. hope you can help. here is the code.

You should add screen components like this:
import LandingScreen from './src/landing';
import House from './src/house';
class App extends React.Component {
render(){
return (
<NavigationContainer>
<Stack.Navigator>
<Stack.Screen name="Home" component={LandingScreen}/>
<Stack.Screen name="House" component={House}/>
</Stack.Navigator>
</NavigationContainer>
)
}
}
also to use props in a class component use this keyword:
<TouchableOpacity onPress={() => this.props.navigation.navigate('House')}>
One more thing, to access props in a class component you call constructor like this :
class Landing extends React.Component{
constructor(props) {
super(props);
}
render(){
return (
<View style={styles.container}>
<View style={{flex: 0.2, flexDirection: 'row',}}>
<ImageBackground source={buttonbannerlower} style={styles.imageBackground}>
<TouchableOpacity>
<Image source={gearIcon} style={styles.iconsLeft}/>
</TouchableOpacity>
<TouchableOpacity>
<Image source={playIcon} style={styles.iconsLeft}/>
</TouchableOpacity>
<TouchableOpacity>
<Image source={talkbuttonblue} style={styles.blueButton}/>
</TouchableOpacity>
<TouchableOpacity>
<Image source={pointerIcon} style={styles.iconPointer}/>
</TouchableOpacity>
<TouchableOpacity onPress={() => this.props.navigation.navigate('House')}>
<Image source={houseIcon} style={styles.iconsRight}/>
</TouchableOpacity>
</ImageBackground>
</View>
<View style={{backgroundColor: 'green', flex: 0.2, alignItems: 'center',}}>
<Text>Hello</Text>
</View>
</View>
)
}
}
You don't need to create functions for the screen components. Just do it like this:
import 'react-native-gesture-handler';
import { StatusBar } from 'expo-status-bar';
import React from 'react';
import { StyleSheet, Text, View, Button} from 'react-native';
import { NavigationContainer } from '#react-navigation/native';
import { createStackNavigator } from '#react-navigation/stack';
const Stack = createStackNavigator()
// PAGES
import LandingScreen from './src/landing';
import House from './src/house';
//CODE
class App extends React.Component {
render(){
return (
<NavigationContainer>
<Stack.Navigator>
<Stack.Screen name="Home" component={LandingScreen}/>
<Stack.Screen name="House" component={House}/>
</Stack.Navigator>
</NavigationContainer>
)
}
}
const styles = {
}
export default App;
Then in your screen components, use the navigation function like this to navigate to other screens.
onPress={() => this.props.navigation.navigate("House")}
