Scan QR code without using google play services

问题:

I have an android app which on local WiFi and doesn't require an internet connection so I am looking for a solution which can scan QR codes without requiring Google Play Services as no internet connection is there so I do not want to update Google Play Services. Currently, I am doing it by using Google Vision API but somehow(if possible) I want to remove this dependency.
