Flutter's Webview - How to clear session status?

I have an App that login to a specific page and execute some commands via Javascript. But when I start the App again it should open the login form. But, instead, it stays logged and goes to the user's screen.

        child: WebView(
              initialUrl:
                  'https://thepage.com/m/customer/account/login/',
              onWebViewCreated: (c) {
                _webviewController = c;
                print("cleaning the cache");
                _webviewController.clearCache();
              },
              onPageFinished: (String page) async {
                setState(() {
                  _isPageLoaded = true;
                });
              },
              javascriptMode: JavascriptMode.unrestricted,
            ),

I tried to clean the cache, but perhaps it is not enough.

You should clear cookies to start a new session, to clear cookies you can do the following `

late final WebViewCookieManager cookieManager = WebViewCookieManager();
 void clearCookies() async {
   await cookieManager.clearCookies();
 }

and call the function ininit`

I think the problem is that you're not clearing the cookies. I was having the same issue with logging in to a page, and it staying logged in, which I fixed by clearing the cookies in the onWebViewCreated callback:

onWebViewCreated: (webViewController) {
    _controller.complete(webViewController);
    webViewController.clearCache();
    final cookieManager = CookieManager();
    cookieManager.clearCookies();
},
