Do we have anything similar to Laravel's notification?

Looks like Laravel has a beautiful multi-channel notification. Most web applications will have some sort notifications (email, sms, etc) built into them and I believe we should have official notification extension.

Is it possible to use Laravel’s notifications with Yii2?

I haven’t seen anything like that specifically for Yii. Laravel ones seems to be tied tightly to Laravel.

It’s unlikely that core team will adopt another extension at this stage because of maintenance cost so it’s a good idea to start such extension yourself.
