Are you sure you have already searched for the same problem?

Some people open new issues but they didn't search for something similar or for the same issue. Please, search for it using the GitHub issue search box or on the official inappwebview.dev website, or, also, using Google, StackOverflow, etc. before posting a new one. You may already find an answer to your problem!

If this is really a new issue, then thank you for raising it. I will investigate it and get back to you as soon as possible. Please, make sure you have given me as much context as possible! Also, if you didn't already, post a code example that can replicate this issue.

In the meantime, you can already search for some possible solutions online! Because this plugin uses native WebView, you can search online for the same issue adding android WebView [MY ERROR HERE] or ios WKWebView [MY ERROR HERE] keywords.

Following these steps can save you, me, and other people a lot of time, thanks!

Are you using a custom WebViewEnvironment for your WebView? In that case, you need to pass it also to the CookieManager.instance method

[ascanime]

Yeah! I passed it but it always return empty list :

final cookies = await CookieManager.instance(
                           webViewEnvironment: webViewEnvironment)
                       .getCookies(url: WebUri("https://sushiscan.net"));

it seems the problem is related to cookies with partition key.
The actual CookieManager implementation doesn't use the current WebView to get the cookies, so it could be useful implement the usage of the webview controller when using the cookie manager methods as it will solve the problem.

More Info about cookie with partition key: https://developer.mozilla.org/en-US/docs/Web/Privacy/Privacy_sandbox/Partitioned_cookies

This means they can only be read within the context of the top-level site they were set on.

The fix will be available in the next beta version 6.2.0-beta.2.

Here is an example of usage:

import 'dart:async';
import 'package:flutter/foundation.dart';
import 'package:flutter/material.dart';
import 'package:flutter_inappwebview/flutter_inappwebview.dart';

WebViewEnvironment? webViewEnvironment;

Future main() async {
  WidgetsFlutterBinding.ensureInitialized();

  if (!kIsWeb && defaultTargetPlatform == TargetPlatform.windows) {
    final availableVersion = await WebViewEnvironment.getAvailableVersion();
    assert(availableVersion != null,
    'Failed to find an installed WebView2 Runtime or non-stable Microsoft Edge installation.');

    webViewEnvironment = await WebViewEnvironment.create(
        settings: WebViewEnvironmentSettings(userDataFolder: 'YOUR_CUSTOM_PATH'));
  }

  runApp(const MaterialApp(home: MyApp()));
}

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

  @override
  State<MyApp> createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  final GlobalKey webViewKey = GlobalKey();

  InAppWebViewSettings settings = InAppWebViewSettings(
      isInspectable: kDebugMode,
  );
  
  @override
  Widget build(BuildContext context) {
    return Scaffold(
        appBar: AppBar(title: const Text("sushiscan.net test")),
        body: SafeArea(
            child: Column(children: <Widget>[
              Expanded(
                child: Stack(
                  children: [
                    InAppWebView(
                      key: webViewKey,
                      webViewEnvironment: webViewEnvironment,
                      initialSettings: settings,
                      initialUrlRequest: URLRequest(url: WebUri("https://sushiscan.net/")),
                      onLoadStop: (controller, url) async {
                        // get cookie manager
                        final cookieManager = CookieManager.instance(
                            webViewEnvironment: webViewEnvironment);
                        // set also the webViewController to get all the possible cookies
                        print(await cookieManager.getCookies(url: url!, 
                            webViewController: controller));
                      },
                    ),
                  ],
                ),
              ),
            ])));
  }
}
