I'm trying to update an app I've developed using react-navigation v4.
Using react-navigation v4 I could get the id using something like console.log(navigation.getParam('id'));
But when I tried the same after updating to v5 of react-navigation it shows me an error and I can't find the right way to get the param id
import React from 'react';
import { View, Text, StyleSheet } from 'react-native';
export default function ShowScreen({ navigation }) {
console.log(navigation.getParam('id'));
return (
<View style={styles.container}>
<Text>Show Screen</Text>
</View>
);
}
const styles = StyleSheet.create({
container: {
flex: 1,
justifyContent: 'center',
alignItems: 'center'
}
});
The other screen where the id is located is it:
import React, { useContext } from 'react';
import { View, Text, StyleSheet, Button } from 'react-native';
import { FlatList, TouchableOpacity } from 'react-native-gesture-handler';
import { Context } from '../../context/BlogContext';
import Icon from 'react-native-vector-icons/Feather'
export default function IndexScreen({ navigation }) {
const { state, addBlogPost, deleteBlogPost } = useContext(Context);
return (
<View style={styles.container}>
<Button
title="Add Post"
onPress={addBlogPost}
/>
<FlatList
data={state}
keyExtractor={(blogPost) => blogPost.title}
renderItem={({ item }) => {
return (
<TouchableOpacity onPress={
() => navigation.navigate('ShowScreen',
{ id: item.id })}>
<View style={styles.row}>
<Text style={styles.title}>
{item.title} -
{item.id}
</Text>
<TouchableOpacity onPress={() => deleteBlogPost(item.id)}>
<Icon style={styles.icon}
name="trash"
/>
</TouchableOpacity>
</View>
</TouchableOpacity>
);
}}
/>
</View>
);
}
const styles = StyleSheet.create({
container: {
flex: 1,
marginTop: 30,
justifyContent: 'center',
alignItems: 'center'
},
row: {
flexDirection: 'row',
justifyContent: 'space-between',
paddingHorizontal: 10,
paddingVertical: 20,
borderTopWidth: 1,
borderColor: '#333'
},
title: {
fontSize: 18
},
icon: {
fontSize: 24
}
});
You can get params using route.params in react navigation v5 more on that read here
just update your code to this
import React from 'react';
import { View, Text, StyleSheet } from 'react-native';
export default function ShowScreen({ navigation,route }) {
const {id} =route.params; //you will get id here via route
return (
<View style={styles.container}>
<Text>Show Screen</Text>
</View>
);
}
const styles = StyleSheet.create({
container: {
flex: 1,
justifyContent: 'center',
alignItems: 'center'
}
});
