title: Confirmation message after redirect in React/Redux
body: <p>I am using <code>React</code>, <code>Redux</code>, <code>Redux Router</code>, and <code>Redux Form</code> for a web application, and I would like to implement an "edit" form. The form lives under the URL <code>/components/1/edit</code>. </p>
  
  <p>When the form is successfully submitted I would like to redirect to <code>/components/1</code> and display a toast with a confirmation message. I can get the redirect to work by hooking into react-form's <code>props.submitSucceeded</code> and rendering a <code>&lt;Redirect/&gt;</code> tag. </p>
  
  <p>But I am not sure how to propagate the confirmation message so that it is displayed. </p>
  
  <p>Ideally something like the React/Redux take on flash messages in Ruby on Rails.</p>
