I want to set Zoom in Camera but not able achieve this using Code Scanner, please suggest any solution.

I'm currently using following version :

I found a solution, You can add a slider in the view and then based on the value you can change the zoom value of the camera using this code: code_scanner.zoom = value

Zoom value needs to be calculated according to maxZoom, but there is no external api.

You can only get it using the Android Api camera.getParameters().getMaxZoom()

You can refer CodeScannerKtx.kt to access getMaxZoom(), which uses reflection to access some private properties.
