Laravel notification class not pass variable

I can't pass sendSms to toHistory method. It is always set as false. How can I do it properly?

class SendMessage extends Notification implements ShouldQueue
{
    use Queueable;
    public $sendSms;

    public function via($notifiable)
    {
        $this->sendSms = true;
    }

    public function toHistory($notifiable) {
        echo $this->sendSms; //return false
    }
}
