Flash->render('somekey');
* Will default to flash if no param is passed
*
* You can pass additional information into the flash message generation. This allows you
* to consolidate all the parameters for a given type of flash message into the view.
*
* ```
* echo $this->Flash->render('flash', ['params' => ['name' => $user['User']['name']]]);
* ```
*
* This would pass the current user's name into the flash message, so you could create personalized
* messages without the controller needing access to that data.
*
* Lastly you can choose the element that is used for rendering the flash message. Using
* custom elements allows you to fully customize how flash messages are generated.
*
* ```
* echo $this->Flash->render('flash', ['element' => 'my_custom_element']);
* ```
*
* If you want to use an element from a plugin for rendering your flash message
* you can use the dot notation for the plugin's element name:
*
* ```
* echo $this->Flash->render('flash', [
* 'element' => 'MyPlugin.my_custom_element',
* ]);
* ```
*
* If you have several messages stored in the Session, each message will be rendered in its own
* element.
*
* @param string $key The [Flash.]key you are rendering in the view.
* @param array $options Additional options to use for the creation of this flash message.
* Supports the 'params', and 'element' keys that are used in the helper.
* @return string|null Rendered flash message or null if flash key does not exist
* in session.
* @throws \UnexpectedValueException If value for flash settings key is not an array.
