*
* ```php
* Yii::$app->session->setFlash('error', 'This is the message');
* Yii::$app->session->setFlash('success', 'This is the message');
* Yii::$app->session->setFlash('info', 'This is the message');

* Multiple messages could be set as follows:
*
* ```php
* Yii::$app->session->setFlash('error', ['Error 1', 'Error 2']);
* ```
