undefined is not an object (evaluating 'RootComponent.prototype')

Question

---------index.js--------

import { AppRegistry } from 'react-native';
import Navigate from './Navigate';

AppRegistry.registerComponent('form1', () => Navigate);

----Navigate.js-----

import React from 'react';
import { StackNavigator, DrawerNavigator } from 'react-navigation';
import TabsList from './TabsList';

export const StackTab1 = StackNavigator({
    TabList: { screen: TabsList},
});

export const Navigate =  DrawerNavigator(
    {
       Tab1: { screen : StackTab1 },
       Tab2: { screen : StackTab1 },
       Tab3: { screen : StackTab1 }
    });

Whenever I try to run my android simulator, I'm getting that error. All modules are installed, no errors being thrown within my IDE except for the one that's appearing in my simulator.

Picture below of error:

You are not importing Navigate properly.

Use

import { Navigate } from './Navigate';

instead of

import Navigate from './Navigate';
