What exactly is your issue? Is the front camera not working on Android or is it just not the default direction? Please update your problem with more information.

Thank you @robingenz for the reply

even though I have set lensFacing: LensFacing.Front

the back camera always opens

[robingenz]

The „scan(…)“ method currently officially only supports „formats“ as option and not „lensFacing“, see https://github.com/capawesome-team/capacitor-mlkit/tree/main/packages/barcode-scanning#scanoptions.
This is because it is not possible on Android with the SDK used. You should use the „startScan(…)“ method if you want to use the front camera.
We will also remove the undocumented iOS code.
For this reason I am closing this issue.
