How to turn off Blackscreen in IOS Web View - ios

Question

Using Quagga.js, we are working on barcode recognition in web view.
It works fine on the mobile web, but it happens on the APP.
The problem is two things below.
The target div provided by Quagga does not contain the camera, but switches to the full screen.
Problem 1 Image
After barcode recognition, the camera remains in the Blackscreen state, not off.
Problem 1 Image
Already unpacked permissions from info.plist.
Privacy - Camera Usage Description
Privacy - Photo Library Additions Usage Description
Below is my code.
openItem.addEventListener("click", () => {
document.querySelector(".barcode_Camera").style.bottom = "0px";
/* Barcode Scan Script */
Quagga.init({
inputStream: {
type : "LiveStream",
target: document.querySelector('#camera_Area'), // Or '#yourElement' (optional)
constraints: {
width: {min: 1280},
height: {min: 480},
facingMode: "environment",
aspectRatio: {min: 1, max: 2}
}
},
locator: {
patchSize: "small",
halfSample: true
},
numOfWorkers: 4,
frequency: 10,
decoder: {
readers : [{
format: "code_93_reader",
config: {}
}],
debug: {
drawBoundingBox: false,
showFrequency: false,
drawScanline: false,
showPattern: false
},
multiple: false
},
}, function (err) {
if (err) {
console.log(err);
return
}
console.log("Initialization finished. Ready to start");
Quagga.start();
});
}); /*Close*/
Quagga.onProcessed(function (result) {
let drawingCtx = Quagga.canvas.ctx.overlay,
drawingCanvas = Quagga.canvas.dom.overlay;
if (result) {
if (result.boxes) {
drawingCtx.clearRect(0, 0, parseInt(drawingCanvas.getAttribute("width")),
parseInt(drawingCanvas.getAttribute("height")));
result.boxes.filter(function (box) {
return box !== result.box;
}).forEach(function (box) {
Quagga.ImageDebug.drawPath(box, {x: 0, y: 1}, drawingCtx, {color: "#88d147", lineWidth: 2});
});
}
}
});
Quagga.onDetected(function (data) {
document.querySelector('#barcode').value = data.codeResult.code;
let closeTarget = closeItem.closest(".barcode_Camera");
document.querySelector(".barcode_Camera").style.bottom = "-100%";
Quagga.stop();
});
I would like to ask for your help if there is anything else I need to do in the info.plist or how I can solve the problem.
