Cookies not persisted if app is closed after cookies are set or deleted

EArminjon commented 16 hours ago

Is there an existing issue for this?

[X] I have searched the existing issues

Current Behavior

All cookies are not available on app start.

Expected Behavior

Cookies should be accessible on app start. Maybe cookies are not fully loaded in memory when the call CookieManager.instance().getCookie is made.

Steps with code example to reproduce

Launch the app
You will see 'Cookie consent page'
Check on log Cookie: null
Click on 'accept cookie consent'
'Cookie consent page' is closed
Check on log Cookie page closed, checking again cookie... and Cookie accepted !
Cookie is well detected on flutter side
Close the app
Launch the app
You see again 'Cookie consent page'
Check on log Cookie: null
Click on appbar back button
Check on log Cookie page closed, checking again cookie... and Cookie accepted !

Code example to reproduce

```dart import 'dart:async'; import 'package:flutter/material.dart'; import 'package:flutter_inappwebview/flutter_inappwebview.dart'; // // // // // // // // // // // // const String url = 'https://coral-caresa-55.tiiny.site/'; void main() => runApp( const MaterialApp( home: Home(), ), ); class Home extends StatefulWidget { const Home({super.key}); @override State createState() => _HomeState(); } class _HomeState extends State { bool? cookieAccepted; @override void initState() { super.initState(); checkCookieConsent(); } Future checkCookieConsent({bool canOpenWebview = true}) async { final Cookie? cookie = await CookieManager.instance().getCookie( url: WebUri(url), name: 'consent', ); print('Cookie: $cookie'); if (cookie == null && canOpenWebview) { await Navigator.push( context, MaterialPageRoute( builder: (BuildContext context) => const CookieConsentPage(), ), ); print('Cookie page closed, checking again cookie...'); return checkCookieConsent(canOpenWebview: false); } else if (cookie == null) { print("Cookie not accepted !"); setState(() => cookieAccepted = false); } else { print("Cookie accepted !"); setState(() => cookieAccepted = true); } } @override Widget build(BuildContext context) { return Scaffold( appBar: AppBar( title: const Text('home'), ), body: Center( child: Column( mainAxisSize: MainAxisSize.min, children: [ cookieAccepted == null ? const CircularProgressIndicator() : Text('Cookie accepted : $cookieAccepted'), const SizedBox(height: 16), ElevatedButton( onPressed: () async { setState(() => cookieAccepted = null); checkCookieConsent(canOpenWebview: false); }, child: const Text('Refresh cookie'), ), const SizedBox(height: 16), ElevatedButton( onPressed: () async { setState(() => cookieAccepted = null); checkCookieConsent(); }, child: const Text('Retry'), ), const SizedBox(height: 16), ElevatedButton( onPressed: () async { await CookieManager.instance().deleteCookie( url: WebUri(url), name: 'consent', ); setState(() => cookieAccepted = null); checkCookieConsent(); }, child: const Text('Delete cookie'), ), ], ), ), ); } } class CookieConsentPage extends StatelessWidget { const CookieConsentPage({super.key}); @override Widget build(BuildContext context) { return Scaffold( appBar: AppBar( title: const Text('Cookie consent page'), ), body: InAppWebView( initialSettings: InAppWebViewSettings( javaScriptEnabled: true, ), onWebViewCreated: (InAppWebViewController controller) { controller.addJavaScriptHandler( handlerName: 'cookieAccepted', callback: (_) { Navigator.of(context).pop(true); }, ); controller.addUserScript( userScript: UserScript( source: """ window.addEventListener('message', function(event) { window.flutter_inappwebview.callHandler('cookieAccepted', true); }); """, forMainFrameOnly: true, injectionTime: UserScriptInjectionTime.AT_DOCUMENT_START, ), ); }, initialUrlRequest: URLRequest( url: WebUri(url), ), ), ); } } ```

Demo :

You can see user accepting cookies, closing the app and then on launch cookie consent page is sadly again visible.

A potential workaround for android is present here : https://github.com/pichillilorenzo/flutter_inappwebview/issues/2354#issuecomment-2419966522.

For iOS i didn't know.

I'm using flutter_inappwebview: 6.0.0 and have same issue in IOS and Android

qkreltms commented 2 hours ago

It's was my fault. there was 'CookieManager.instance().deleteCookies(url: ...));' in my onViewCreated
