deleteCookie method

Future<void> deleteCookie({
  1. required WebUri url,
  2. required String name,
  3. String path = "/",
  4. String? domain,
  5. @Deprecated("Use webViewController instead") InAppWebViewController? iosBelow11WebViewController,
  6. InAppWebViewController? webViewController,
})

Removes a cookie by its name for the given url, domain and path.

The default value of path is "/".

webViewController is used for deleting the cookie (also session-only cookie) using JavaScript (cookie with isHttpOnly enabled cannot be deleted, see: https://developer.mozilla.org/en-US/docs/Web/HTTP/Cookies#restrict_access_to_cookies) from the current context of the WebView managed by that controller when you need to target iOS below 11, MacOS below 10.13 and Web platform. JavaScript must be enabled in order to work. In this case the url parameter is ignored.

NOTE for iOS below 11.0 and MacOS below 10.13: If webViewController is null or JavaScript is disabled for it, it will try to use a HeadlessInAppWebView to delete the cookie (session-only cookie and cookie with isHttpOnly enabled won't be deleted!).

NOTE for Web: this method will have effect only if the iframe has the same origin. If webViewController is null or JavaScript is disabled for it, it will try to use a HeadlessInAppWebView to delete the cookie (session-only cookie and cookie with isHttpOnly enabled won't be deleted!).
