The plugin has webViewObject.ClearCache(true) for Android/iOS. For any platform, adding a url parameter is a most reliable way:

        webViewObject.LoadURL(Url.Replace(" ", "%20") + "?_=" + (System.DateTime.UtcNow.Subtract(new System.DateTime(1970, 1, 1))).TotalSeconds);

You can also utilize the following to forcibly reload the current page.

        webViewObject.EvaluateJS("window.location.href = window.location.href.replace(/#.*$/, '')")

webViewObject.ClearCache(true);
it take little long time to load url in webview means its shows black screen for long time.

Yes, so it is better to utilize other methods. If you control the html server, you can also disable cache by apache .htaccess, for example (cf. https://stackoverflow.com/questions/22891965/how-to-disable-cache-of-apache/22892020#22892020 ). Such settings should be okay at least for debugging.
