google auth problems

I have been having this issue for quite a while. This functionality was working fine on all flutter platforms, but then suddenly stopped working.

TL;DR

Title: Google Auth Problems Developers have encountered issues with Google authentication in their Flutter app across multiple platforms. The functionality was previously working but stopped abruptly. Solution: 1. In the `auth.html` file, ensure that authentication is completed and closed properly. The JavaScript code should send a post message to the Flutter app and close the window. 2. In the `androidManifest.xml` file, make sure the activity for the CallbackActivity has the correct data scheme specified according to your Flutter app's package name. 3. Check the Dart code for implementing Google sign-in. Make sure the necessary client and account configurations are set and the

on flutter web

TypeScript

Client client(ClientRef ref) {
  return Client().setEndpoint('https://cloud.appwrite.io/v1').setProject('linearprogrammingapp');
}

Account account(AccountRef ref) {
  final client = ref.watch(clientProvider);
  return Account(client);
}

Future<void> signInWithGoogle() async {
    final account = ref.read(accountProvider);
    final result = await account.createOAuth2Session(
      provider: 'google',
      success: _successCallback(),
      failure: _failureCallback(),
    );
    debugPrint('google siginresult: $result');
  }

String? _successCallback() {
    if (kIsWeb) {
      final Uri? location = href == null ? null : Uri.parse(href!);
      return '${location?.origin}/auth.html';
    }
    switch (defaultTargetPlatform) {
      case TargetPlatform.android:
        return null;
      case TargetPlatform.fuchsia:
        return null;
      case TargetPlatform.iOS:
        return null;
      case TargetPlatform.macOS:
        return null;
      case TargetPlatform.linux || TargetPlatform.windows:
        return 'http://localhost:1001/auth/oauth2/success';
      default:
        throw UnsupportedError('Unsupported platform');
    }
  }

  String? _failureCallback() {
    switch (defaultTargetPlatform) {
      default:
        return '';
    }
  }

for androidManifest

TypeScript

<activity android:name="io.appwrite.views.CallbackActivity" android:exported="true">
      <intent-filter android:label="android_web_auth">
        <action android:name="android.intent.action.VIEW" />
        <category android:name="android.intent.category.DEFAULT" />
        <category android:name="android.intent.category.BROWSABLE" />
        <data android:scheme="appwrite-callback-linearprogrammingapp" />
      </intent-filter>
    </activity>

auth.html

TypeScript

<!DOCTYPE html>
<title>Authentication complete</title>
<p>Authentication is complete. If this does not happen automatically, please
  close the window.</p>
<script>
  window.opener.postMessage({
    'flutter-web-auth-2': window.location.href
  }, window.location.origin);
  window.close();
</script>

I would appreciate any help, on solving this. Thank you.
