The IOS camera freezes, on Android it works fine

[MiguelAngelBadi]

Hello, I have modified the code to scan QR codes one after the other without having to click on Scan QR. On Android it works perfectly for me but on IOS the camera freezes. Could you help me?

The code is the following:

fun QrScannerCompose() {

var qrCodeURL by remember { mutableStateOf("") }
var startBarCodeScan by remember { mutableStateOf(false) }
var flashlightOn by remember { mutableStateOf(false) }
var launchGallery by remember { mutableStateOf(value = false) }
val snackBarHostState = LocalSnackBarHostState.current
val coroutineScope = rememberCoroutineScope()

Box(modifier = Modifier.fillMaxSize().statusBarsPadding()) {
    Column(
        modifier = Modifier
            .background(color = Color.White)
            .windowInsetsPadding(WindowInsets.safeDrawing)
            .fillMaxSize(),
        verticalArrangement = Arrangement.Center,
        horizontalAlignment = Alignment.CenterHorizontally
    ) {
            Column(
                modifier = Modifier
                    .background(color = Color.Black)
                    .fillMaxSize(),
                verticalArrangement = Arrangement.Center,
                horizontalAlignment = Alignment.CenterHorizontally
            ) {
                Box(
                    modifier = Modifier
                        .size(250.dp)
                        .clip(shape = RoundedCornerShape(size = 14.dp))
                        .clipToBounds()
                        .border(2.dp, Color.Gray, RoundedCornerShape(size = 14.dp)),
                    contentAlignment = Alignment.Center
                ) {
                    QrScanner(
                        modifier = Modifier
                            .clipToBounds()
                            .clip(shape = RoundedCornerShape(size = 14.dp)),
                        flashlightOn = flashlightOn,
                        launchGallery = launchGallery,
                        onCompletion = {
                            qrCodeURL = it
                            startBarCodeScan = false
                        },
                        onGalleryCallBackHandler = {
                            launchGallery = it
                        },
                        onFailure = {
                            coroutineScope.launch {
                                if (it.isEmpty()) {
                                    snackBarHostState.showSnackbar("Invalid qr code")
                                } else {
                                    snackBarHostState.showSnackbar(it)
                                }
                            }
                        }
                    )
                }

                Box(
                    modifier = Modifier
                        .padding(start = 20.dp, end = 20.dp, top = 30.dp)
                        .background(
                            color = Color(0xFFF9F9F9),
                            shape = RoundedCornerShape(25.dp)
                        )
                        .height(35.dp),
                    contentAlignment = Alignment.Center
                ) {
                    Row(
                        modifier = Modifier
                            .padding(vertical = 5.dp, horizontal = 18.dp),
                        verticalAlignment = Alignment.CenterVertically,
                        horizontalArrangement = Arrangement.spacedBy(11.dp)
                    ) {
                        Icon(imageVector = if (flashlightOn) Icons.Filled.FlashOn else Icons.Filled.FlashOff,
                            "flash",
                            modifier = Modifier
                                .size(24.dp)
                                .clickable {
                                    flashlightOn = !flashlightOn
                                })

                        VerticalDivider(
                            modifier = Modifier,
                            thickness = 1.dp,
                            color = Color(0xFFD8D8D8)
                        )

                        Image(
                            painter = painterResource(Res.drawable.ic_gallery_icon),
                            contentDescription = "gallery",
                            contentScale = ContentScale.Fit,
                            modifier = Modifier

                                .clickable {
                                    launchGallery = true
                                }
                        )
                    }

                Spacer(modifier = Modifier.height(8.dp))

                }
            }
    }
}

}

I attach the video where you can see that on Android it works perfectly, and on IOS it freezes after scanning the first QR code.
