CODE EXAMPLE FOR JAVASCRIPT

Error: `createStackNavigator()` has been moved to `react-navigation-stack`.

For the StackNavigator you have to install react-navigation-stack using:

npm i react-navigation-stack   //or yarn add react-navigation-stack

after that, go to the file where you define createStackNavigator and change:

import { createStackNavigator } from 'react-navigation'

to:

import { createStackNavigator } from 'react-navigation-stack'
