How to use Firebase to delete or update data with Laravel 5?

App\EventCal::where('id', 7)->delete();

Above is the laravel query to delete data from the given database. But it was not supported with firebase?

\App\EventCal::create(['task' => 'Write blog post','is_done' => false]);

When I'm trying the above create query it worked fine. I want to know how to achieve the above delete query statement even.
