React Native- Invariant Violation: The navigation prop is missing for this navigator | react-navigation 3- navigation prop is missing for this navigator.

Hello Friend,
       Recently I faced few issue while implementing the react-navigation in my app.
I spent lots of time in it and then finally I found the actual cause of it.

1. undefined is not an object (evaluating 'RNGestureHandlerModule.State')

Then I follow following steps to resolve this,

  1. remove node_modules and package-lock.json
  2. npm install
  3. npm install --save react-navigation
  4. npm install --save react-native-gesture-handler
  5. react-native link
After following this I face another issue i:e,

2. Invariant Violation: The navigation prop is missing for this navigator. In 
react-navigation 3 you must set up your app container directly. More info:

Note  This is an react-navigation 3.0 bug. You can go through the below link for more details. 

- React Navigation 3.0 has a number of breaking changes including an explicit app container required for the root navigator.

In the past, any navigator could act as the navigation container at the top-level of your app because they were all wrapped in “navigation containers”. The navigation container, now known as an app container, is a higher-order-component that maintains the navigation state of your app and handles interacting with the outside world to turn linking events into navigation actions and so on.

In v2 and earlier, the containers in React Navigation are automatically provided by the create Navigator functions. As of v3, you are required to use the container directly. In v3 we also renamed createNavigationContainer to createAppContainer.

Below are the complete code,

 * This is an example code for Navigator
import React, { Component } from 'react';
import {createStackNavigator,createAppContainer} from 'react-navigation';
import FirstPage from './src/component/FirstPage';
import SecondPage from './src/component/SecondPage';
//import all the screens we are going to switch 
const RootStack = createStackNavigator({
    //Constant which holds all the screens like index of any book 
    FirstPage: { screen: FirstPage }, 
    //First entry by default be our first screen if we do not define initialRouteName
    SecondPage: { screen: SecondPage }, 
    initialRouteName: 'FirstPage',
const App = createAppContainer(RootStack);

Hope this will helps someone........

Enjoy coding..... :)
