fireSystemEvent(string $event, array $params = [], bool $halt = true)
Fires a combination of local and global events. The first segment is removed from the event name locally and the local object is passed as the first argument to the event globally. Halting is also enabled by default.
For example:
$this->fireSystemEvent('admin.form.myEvent', ['my value']);Is equivalent to:
$this->fireEvent('form.myEvent', ['myvalue'], true);
Event::fire('admin.form.myEvent', [$this, 'myvalue'], true);
