Torch is not working

[stamahto]

I am encountering an issue with the torch.on() and torch.off() functions. When I call torch.on(), no noticeable changes occur, even console don't log any message.

I´m using the latest version 1.1.4

What OS are you using?

Android 13
I made my own custom torch function, which get user media by deviceId from my state and works fine.

    const handleToggleTorch = useCallback(() => {
        navigator.mediaDevices.getUserMedia({ video: { deviceId: deviceId } }).then(stream => {
            const track = stream.getVideoTracks()[0];
            track.applyConstraints({
                advanced: [{ torch: !isTorchOn } as any]
            });
            setIsTorchOn(!isTorchOn);
        });
    }, [deviceId, isTorchOn]);

As I look into your hook, did you consider put videoTrackRef into useCallback dependencies?

Btw. if you would update the code, please also update @zxing/library version

That's strange! Unfortunately I'm in no possession of a torch-compatible device, so any help I could get with this would be highly appreciated!

@zxing/library has been updated now, in 2.0.0!
