WebViewX Flutter not pass token - flutter

Question

the dart code below displays a web pdf by authenticating with a token to a backend via the webviewx pub: , the token however on android is not passed and the page displays an error of authentication, what should I change to ensure that the token is also passed on android? How to solve this error by WebViewX?
Dart Code:
import 'dart:developer';
import 'dart:io';
import 'dart:math';
import 'package:flutter/material.dart';
import 'package:webviewx/webviewx.dart';
class WebViewXPage extends StatefulWidget {
final Url, Token;
WebViewXPage(this.Url, this.Token);
#override
_WebViewXPageState createState() => _WebViewXPageState();
}
class _WebViewXPageState extends State<WebViewXPage> {
late WebViewXController webviewController;
final initialContent =
'<h4> This is some hardcoded HTML code embedded inside the webview <h4> <h2> Hello world! <h2>';
final executeJsErrorMessage =
'Failed to execute this task because the current content is (probably) URL that allows iframe embedding, on Web.\n\n'
'A short reason for this is that, when a normal URL is embedded in the iframe, you do not actually own that content so you cant call your custom functions\n'
'(read the documentation to find out why).';
Size get screenSize => MediaQuery.of(context).size;

webviewController.dispose();
