+       *
        * 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.
+       *
        * ```

+       *
        * The above would generate a flash message with a custom class name. Using $attrs['params'] you
        * can pass additional data into the element rendering that will be made available as local variables
        * when the element is rendered:
+       *
        * ```
        * echo $this->Session->flash('flash', array('params' => array('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 rendered when creating the flash message. Using
        * custom elements allows you to fully customize how flash messages are generated.
+       *
        * ```
        * echo $this->Session->flash('flash', array('element' => 'my_custom_element'));
        * ```
+       *

        * plugin param:
+       *
        * ```
        * echo $this->Session->flash('flash', array(
        *                'element' => 'my_custom_element',
        *                'params' => array('plugin' => 'my_plugin')
        * ));
        * ```
+       *
        * @param string $key The [Message.]key you are rendering in the view.
        * @param array $attrs Additional attributes to use for the creation of this flash message.
        *    Supports the 'params', and 'element' keys that are used in the helper.
        * @return string
        * @link http://book.cakephp.org/2.0/en/core-libraries/helpers/session.html#SessionHelper::flash
        * @deprecated 3.0.0 Since 2.7, use FlashHelper::render() instead.
