Just Add onWebResourceError method to your Webview.

    WebView(
        onWebResourceError: (WebResourceError webviewerrr) {
            print("Handle your Error Page here");
        },
        initialUrl: "your url"
        javascriptMode: JavascriptMode.unrestricted,
        onPageFinished: (String url) {
            print('Page finished loading:');
        },
    );
