Jetpack compose Barcode/QR code scanner
Jetpack compose Barcode QR code scanner using Google’s ML Kit and CameraX. In this article, we’ll discover how to build a jetpack compose Barcode scanner using Google the ML Kit and Jetpack CameraX.
This is the first version of ML Kit as a standalone SDK that is independent of Firebase. The SDK includes all of the on-device APIs previously available through Firebase’s ML Kit for Firebase SDK. See ML Kit Release Notes.
A stand-alone library to run ML on your device that you can use in conjunction with without Firebase. Jetpack compose Barcode QR code scanner
