Exploring Navigation in React Native - Stack Navigator

I am encountering an issue with stack navigator while navigating between screens in my react native app. The error arises when using this.props.navigation.navigate. Please help me identify what I might be doing incorrectly here.https://i.sstatic.net/VPFVO.png

Although I am also utilizing react-native router-flux within my app, there is a specific need to use stack navigator. This necessity arises from the structure of my app which includes a home page displaying content from a blog feed. Clicking on "read more" should lead to a detailed view of that particular blog feed item. Hence, stack navigator comes into play for this purpose. Here's a snippet of my code:

Home.js:

import React, { Component } from 'react';
...

Navigation.js:

import React,{Component} from 'react';
...

The objective is to have clicking on "read more" open the detailed view of the selected blog feed entry. Any assistance offered would be greatly appreciated. Thank you in advance!

When dealing with the onPress callback, keep in mind that this could potentially change its value. This means that accessing this.props.navigation may not yield the expected result. It's recommended to store the value of navigation in a separate variable and use that instead of relying on this within the callback function. Check out the example code snippet below for reference.

render() {
  const {navigation} = this.props;
  ...
  <TouchableOpacity onPress={() => navigation.navigate('Detail')}>
  ...
}

It seems that @Harlan is requesting something similar to this:

    import AppNavigator from './Navigation.js'

    class MainApp extends React.Component {
       render(){
         return(
           <View>
            <AppNavigator/>
           </View>
         )
       }
    }

    AppRegistry.registerComponent( 'mainApp', () => MainApp );

It appears that he might have a valid point as your navigator in Navigation.js is not properly exported. Without the code snippet above, your components may not have access to navigation in their props.
