Could not find "store" in either the context or props of "Connect(App)"

• Provider, passes the store to the component nested within it and generally only needed to be applied to the root component (in your case <RootContainer>

• connect connect with the component providing store and not the component that has store provided to it.

SUGGESTED SOLUTION:

MOVE the connect to the <RootContainer> component file instead, and pass connect the RootContainer and not the App component:

export default connect(
  (state) => ({
    state: state.reducer
  }),
  (dispatch) => ({
    actions: bindActionCreators(screenActions, dispatch)
  })
)(RootContainer);  // <<--- here :)

UPDATE:

Given the OP wants to achieve all of this in the same file, you'll have to create a React element that represents your Redux container created from connect, so:

'use strict';
import React, { Component } from 'react';
import { createStore, applyMiddleware, combineReducers, bindActionCreators } from 'redux';
import { Provider, connect } from 'react-redux';
import thunk from 'redux-thunk';
import * as screenActions from './redux/actions/screenActions';

import * as reducers from './redux/stores/reducers';

const createStoreWithMiddleware = applyMiddleware(thunk)(createStore);
const reducer = combineReducers(reducers);
const store = createStoreWithMiddleware(reducer);

import RootContainer from './redux/views/containers/rootContainer';

// name has to be capitalised for React to recognise it as an element in JSX
const ConnectedRoot = connect(
  (state) => ({
    state: state.reducer
  }),
  (dispatch) => ({
    actions: bindActionCreators(screenActions, dispatch)
  })
)(RootContainer);

class App extends Component {
  render() {
    const { state, actions } = this.props;
    return (
      <Provider store={store}>
        <ConnectedRoot />    <------USE IT HERE
      </Provider>
    );
  }
}
