React Native navigation v3 with redux

I am trying to setup react navigation v3 with redux. In the react navigation docs I can successfully set up my navigation and it works fine without redux added. However, when I attempt to add my redux class App extends React.Component{...} and hook up my actions it throws the following error:

Invariant Violation: Invariant Violation: Could not find "store" in the context of "Connect(AuthScreen)". Either wrap the root component in a , or pass a custom React context provider to and the corresponding React context consumer to Connect(AuthScreen) in connect options.

App.js

const MainNavigator = createBottomTabNavigator({
  welcome: { screen: WelcomeScreen },
  auth: { screen: AuthScreen },
  main: {
    screen: createBottomTabNavigator({
      map: { screen: MapScreen },
      deck: { screen: DeckScreen },
      review: {
        screen: createStackNavigator({
          review: { screen: ReviewScreen },
          settings: { screen: SettingsScreen }
        }) 
      }
    })
  }
});

const AppContainer = createAppContainer(MainNavigator);

class App extends React.Component {
  render() {
    return (
      <Provider store={store}>
        <AppContainer />
      </Provider>
    );
  }
}


export default AppContainer;

Here is my AuthScreen I want to connect redux to:

class AuthScreen extends Component {
    componentDidMount(){
        console.log('This is this.props in AuthScreen:')
        console.log(this.props);
        this.props.facebookLogin();
    }
    render(){
        return(
            <View>
                <Text>AuthScreen</Text>
            </View>
        )
    }
}

export default connect(null, actions)(AuthScreen);

I suspect I am not allowed to wrap the <Provider> tags around the app container like this, can someone give some insight on how this could be done?

Here's a simple example to get you started with React Navigation 3.x and Redux:

App.js

import React, {Component} from 'react';
import {createStackNavigator, createAppContainer} from 'react-navigation';
import {Provider} from 'react-redux';
import {createStore, applyMiddleware} from 'redux';

import Reducers from './src/Reducers';

import Preload from './src/screens/Preload';

let store = createStore(Reducers);

const AppNavigator = createStackNavigator({
  Preload: {
    screen: Preload,
  },
});

const AppContainer = createAppContainer(AppNavigator);

export default class App extends Component {
  render () {
    return (
        <Provider store={store}>
          <AppContainer/>
        </Provider>
    )
  }
}

So, I'll post what I have and hopefully it will help. I have a separated file (AppNavigation.js) that handles all the navigation for my app. On this AppNavigation I have this:

const RootNavigator = createStackNavigator({
  <Code here>
})

My RootNavigator is inside the AppContainer

const AppContainer = createAppContainer(RootNavigator)

Then, on my class I render the AppContainer.

class AppNavigation extends Component {
  constructor(props) {
    super(props);
  }

  render() {
    return <AppContainer screenProps={this.props} />
  }
}
export default connect(mapStateToProps, mapDispatchToProps)(AppNavigation);

Then, on my App.js I 'connect' my store to the RootNavigator

export default class App extends React.Component {

  render() {
    return (
      <Provider store={store}>
        <RootNavigator />
      </Provider>
    )
  }
}

So, long story short: you should wrap your MainNavigator on your Provider tag.

EDIT:

const rootReducer = combineReducers({
  reducer1,
  reducer2,
  reducer3...,
})

export default createStore(
  rootReducer,
  undefined,
  applyMiddleware(...middleware)
)

So with these reducers you can 'connect' them to your component via mapStateToProps and use the state of the reducers on them.
