undefined is not an object (evaluating '(0 _reactnavigation.DrawerNavigator)') - react-native

Question

I have created customized sidebar and have 5 to 6 screens. I am using NativeBase and want to open Sidebar with DrawerNavigator option but when I applied following code it was getting issue.
Drawer Navigator code
import React, { Component } from "react";
import WelcomeScreen from './screens/WelcomeScreen';
import ContactScreen from './screens/ContactScreen';
import DepartmentScreen from './screens/DepartmentScreen';
import EmailServiceScreen from './screens/EmailServiceScreen';
import MoreScreen from './screens/MoreScreen';
import SideBar from "./SideBar.js";
import { DrawerNavigator } from "react-navigation";
const SidebarNavigator = DrawerNavigator(
{
Home: { screen: WelcomeScreen },
Contact: { screen: ContactScreen },
Department: { screen: DepartmentScreen },
EmailService: { screen: EmailServiceScreen },
More: { screen: MoreScreen }
},
{
contentComponent: props => <SideBar {...props} />
}
);
export default SidebarNavigator;
Calling them in APP.Js as propos. See following code from APP.JS
import SidebarNavigator from './src/SidebarNavigator';
class App extends Component {
render() {
const store = createStore(reducers, {}, applyMiddleware(ReduxThunk));
return (
<Provider store={createStore(reducers)}>
<Root>
<Router /> // It's a stack navigator which is working fine
<SidebarNavigator />
</Root>
</Provider>
);
}
}
console.disableYellowBox = true;
export default App;

Answer 1

The error here is that you are using DrawerNavigation instead of createDrawerNavigator.
Just do those changes and you should be good
import { createDrawerNavigator } from "react-navigation";
...
const SidebarNavigator = createDrawerNavigator( ... )

Answer 2

You can try this code
You can use createDrawerNavigator and createAppContainer
import { createDrawerNavigator, createAppContainer } from "react-navigation";
...
const SidebarNavigator = createDrawerNavigator( ... )
const AppContainer = createAppContainer(SidebarNavigator);
// Now AppContainer is the main component for React to render
export default AppContainer;
