title: createProvider is not exported from react-redux?
body: <p>I am trying to create multiple distinct Redux stores, for that am using <code>createProvider()</code> method in 'react-redux'.</p>
  
  <p>I have installed the latest react-redux version(7.1.0), but am getting the error like <em>"createProvider is not exported from react-redux"</em>. When i gone through the node modules, i couldn't able to find the <code>createProvider</code> inside the src of react-redux. Is it a version issue or did i miss something in the code. I have shared you the following code snippet as :</p>
  
  <p><em>Provider.js</em></p>
  
  <pre><code>import { createProvider } from "react-redux";
  
  export const STORE_KEY = "myComponentStore";    
  export const Provider = createProvider(STORE_KEY);
  </code></pre>
  
  <p><em>TestComponent.js</em></p>
  
  <pre><code>import React, { Component } from "react";
  import { createStore } from "redux";
  import Mycomponent from "./MyComponent";
  
  import { Provider } from "./Provider";
  
  const reducer = {};
  
  const initialState = {
    title: "multiple store"
  };
  
  const store = createStore(reducer, initialState);
  
  class TestComponent extends Component {
    render() {
      return (
        &lt;Provider store={store}&gt;
          &lt;Mycomponent /&gt;
        &lt;/Provider&gt;
      );
    }
  }
  export default TestComponent;
  </code></pre>
  
  <p><em>Mycomponent.js</em></p>
  
  <pre><code>import React, { Component } from "react";
  
  import { connect } from "./Connect";
  
  class MyComponent extends Component {
    render() {
      return &lt;div&gt;{this.props.title}&lt;/div&gt;;
    }
  }
  
  export default connect(function mapStateToProps(state) {
    return {
      title: state.title
    };
  })(MyComponent);
  </code></pre>
