Black Screen when I open webview

[EtcGonza]

Greetings! I'm trying to open a webpage with desktop_webview_window. But when I do it I get this error

Inspection is enabled by default for process or parent application with 'com.apple.security.get-task-allow' entitlement linked against old SDK. Use `inspectable` API to enable inspection on newer SDKs.

════════ Exception caught by Flutter framework ═════════════════════════════════
The following assertion was thrown during runApp:
Zone mismatch.

The Flutter bindings were initialized in a different zone than is now being used. This will likely cause confusion and bugs as any zone-specific configuration will inconsistently use the configuration of the original binding initialization zone or this zone based on hard-to-predict factors such as which zone was active when a particular callback was set.
It is important to use the same zone when calling `ensureInitialized` on the binding as when calling `runApp` later.
To make this warning fatal, set BindingBase.debugZoneErrorsAreFatal to true before the bindings are initialized (i.e. as the first statement in `void main() { }`).
When the exception was thrown, this was the stack
#0      BindingBase.debugCheckZone.<anonymous closure>

If I try to open the webview again I get this error too

This is my code

import 'package:flutter/material.dart';
import 'package:desktop_webview_window/desktop_webview_window.dart';

void main(List<String> args) async {
  WidgetsFlutterBinding.ensureInitialized();

  if (runWebViewTitleBarWidget(args)) {
    return;
  }

  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      debugShowCheckedModeBanner: false,
      title: 'Flutter Demo',
      theme: ThemeData(
        colorScheme: ColorScheme.fromSeed(seedColor: Colors.deepPurple),
        useMaterial3: true,
      ),
      home: const WebView(),
    );
  }
}

class WebView extends StatefulWidget {
  const WebView({super.key});

  @override
  State<WebView> createState() => _WebViewState();
}

class _WebViewState extends State<WebView> {
  @override
  void initState() {
    super.initState();
    // web();
  }

  void web() async {
    final webview = await WebviewWindow.create(
      configuration: const CreateConfiguration(title: "WebViewExample"),
    );
    webview.launch("https://www.google.com/");
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Test'),
      ),
      body: ElevatedButton(onPressed: web, child: Text('Open')),
    );
  }
}
