    new WebVuw(
        initialUrl: 'www.url.com',
        enableJavascript: true,
        pullToRefresh: true,
        header: {
            .....
        }

        // to load html string
        // html: '<body><h1>this is web vuw</h1></body>',
        gestureRecognizers: <Factory<OneSequenceGestureRecognizer>>[
            Factory<OneSequenceGestureRecognizer>(
                () => EagerGestureRecognizer(),
            ),
        ].toSet(),
        javaScriptMode: JavaScriptMode.unrestricted,
        onWebViewCreated: (WebVuwController webViewController) {
            _controller.complete(webViewController);
        }
    )

Listen to webview events

First 1️⃣ 👇🏻

//    ...
    StreamSubscription _ssWebVuwEvents;

    @override
    Widget build(BuildContext context) {
        return FutureBuilder<WebVuwController>(
        future: _controller.future,
        builder:
            (BuildContext context, AsyncSnapshot<WebVuwController> snapshot) {
            final webViewReady = 
                snapshot.connectionState == ConnectionState.done;
            final controller = snapshot.data;

            if (webViewReady) {
                // You can now call the functions
                // controller.stopLoading();
                _ssWebVuwEvents = controller.onEvents().listen((events) {
                    print('Events 😎=> $events');
                });
            }
    ...

Second 2️⃣ 👇🏻

    @override
    void dispose() {
        if (_ssWebVuwEvents != null) _ssWebVuwEvents.cancel();
        super.dispose();
    }
    ..
