Intercepting fetch request on Flutter webview_flutter package - flutter

Question

How can i intercept (listening) fetch request on webview_flutter package? Is it posible?
Nowadays, i was inspected flutter_inappwebview plugin. But this plugin is deprecated. Last commit on GitHub is 12 months ago.
Therefore i want intercept fetch request on webview_flutter, official Flutter package.
Is it posible making this flutter way or javascript way?
SOLVED # 👍
I have found a solve.
I have created two interceptor on js side
1. Fetch API Interceptor
//FETCH INTERCEPTOR
const { fetch: originalFetch } = window;
window.fetch = async (...args) => {
let [resource, config] = args;
var requestedURL = resource.valueOf();
console.log("requested url: "+requestedURL)
if (requestedURL=="https://my-json-server.typicode.com/typicode/demo/comments"){
var resp = new Response().statusText="Status not sent";
document.querySelector('.status').style.backgroundColor="red";
return resp;
}else{
const response = await originalFetch(resource, config);
document.querySelector('.status').style.backgroundColor="green";
return response;
}
};
Basically replacing original window fetch api to our created fake fetch api. It's called Monkey Patching.
2. XMLHttpRequest Interceptor
//XHR INTERCEPTOR
((() => {
const origOpen = XMLHttpRequest.prototype.open;
XMLHttpRequest.prototype.open = function() {
console.log('request started!');
this.addEventListener('load', function() {
console.log(this.responseURL);
});
// origOpen.apply(this, arguments);
};
}))();
and we can inject these js codes to webpage opened by Webview. with:
