Passing props and navigation in react navigation - react-native

Question

I have a parent functional component Layout which needs props to have access to it's children. However, as I am using navigation 5.x, I also need to pass navigation but what I have tried hasn't worked yet. Here is my work
import { Container, Header, Content, Left, Right } from 'native-base';
import React from 'react';
import { View } from 'react-native';
import Icon from 'react-native-vector-icons/FontAwesome';
import { useNavigation } from '#react-navigation/native';
const Layout = (props, navigation) => {
return (
<Container >
<Header style={{ alignItems: 'center', backgroundColor: '#3a455c', height: 50 }}>
<Left style={{ flexDirection: 'row' }}>
<MaterialIcon style={{ color: 'white', marginRight: 10 }} onPress={ () => console.log(navigation) } size={30} color="black" name= 'menu' />
</Left>
<Icon onPress={ () => navigation.navigate('Index') } size={20} style={{marginTop: 4, marginLeft: 130}} color="white" name= 'home' />
<Right style={{ flexDirection: 'row' }}>
<Icon onPress={ () => navigation.navigate('Index') } size={20} style={{marginTop: 4}} color="green" name= 'user' />
</Right>
</Header>
<Content >
<View>
{ props.children }
</View>
</Content>
</Container>
);
}
export default Layout;
Layout component is being rendered in Newsletter component
function Newsletter() {
const navigation = useNavigation();
return (
<Layout >
<ScrollView style={{ marginTop: 40, marginLeft: 12 }}>
<Text style={{fontSize: 24, fontFamily: 'sans-serif-medium', textAlign: 'center', fontWeight: 'bold'}} > Directed Distraction </Text>
<View>
<Text style={{ marginTop: 12, fontSize: 18, textAlign: 'left', fontStyle: 'italic' }}>

}
navigation is printed just as an object{}. Help would be appreciated.

Answer 1

I will explain something first: the navigation object gets passed to the prop object when this component rendered as a screen for any navigator and not next to it
so you can do a couple of things now
1- const Layout = (props) and you can access the navigation like how you access the children like this props.navigation.navigate('Index')
2- or you can simply destructure anything you want from the props object like this: const Layout = ({children, navigation}) => { this way you can type less as you don't have to reference the props object anymore and it will be navigation.navigate('Index')
3- if your component does not rendered by a navigator, then the navigation object will not be passed to the prop object and it will be undefined -- in this case there is a simple solution you can do and it's not the only solution:
I see that you already importing useNavigation and useNavigation exposes the navigation object out of the box for you, so what you can do inside your component is: const navigation = useNavigation() then you can use navigation as always, but don't forget to remove the navigation from the component parameters
here you can find more details about the useNavigation hook useNavigation
4- here I will add the code for the layout component which I believe it should work
import { Container, Header, Content, Left, Right } from 'native-base';
import React from 'react';
import { View } from 'react-native';
import Icon from 'react-native-vector-icons/FontAwesome';
import { useNavigation } from '#react-navigation/native';
const Layout = (props) => {
const navigation = useNavigation();
return (
<Container >
<Header style={{ alignItems: 'center', backgroundColor: '#3a455c', height: 50 }}>
<Left style={{ flexDirection: 'row' }}>
<MaterialIcon style={{ color: 'white', marginRight: 10 }} onPress={ () => console.log(navigation) } size={30} color="black" name= 'menu' />
</Left>
<Icon onPress={ () => navigation.navigate('Index') } size={20} style={{marginTop: 4, marginLeft: 130}} color="white" name= 'home' />
<Right style={{ flexDirection: 'row' }}>
<Icon onPress={ () => navigation.navigate('Index') } size={20} style={{marginTop: 4}} color="green" name= 'user' />
</Right>
</Header>
<Content >
<View>
{ props.children }
</View>
</Content>
</Container>
);
}
export default Layout;
there other options like passing a handler to onPress and executing this function from the component where has access to the navigation object
I hope this is useful to you. let me know if it works
