undefined is not an object (evaluating RNGestureHandlerModule.State)

I'm trying to create a stack navigator and it gives me the above mentioned error. My code as bellow



 import React, {Component} from 'react';
import { createStore, applyMiddleware, compose } from 'redux';
import NavigationService from './Utils/NavigationService'
import { Provider } from 'react-redux';
import thunk from 'redux-thunk';
import { createStackNavigator, createSwitchNavigator } from 'react-navigation';
import Stat from './App/statsScreen'
import Sec from './App/loginScreen'


const RootStack = createStackNavigator(
{
Home: Stat,
Details: Sec
},
{
initialRouteName: "Details"
}
);

const AppNavigator = createSwitchNavigator(
{

App: RootStack,

}, {
initialRouteName: 'App'
}
);

export const store = (__DEV__) ? createStore(rootReducer, compose(applyMiddleware(thunk), window.devToolsExtension ? window.devToolsExtension() : f => f)) : createStore(rootReducer, applyMiddleware(thunk));

export default class App extends React.Component {

render() {
return (
<Provider store={store}>
<AppNavigator
ref={navigatorRef => {
NavigationService.setTopLevelNavigator(navigatorRef);
}}
/>
</Provider>
);
}

}


However If I comment the "createStackNavigator" part and export a general class it works. What am I missing here? and with this code why is it trowing me an error like that ?
