Scaffold 로 감싼다

Scaffold(
      appBar: AppBar(
        title:const Text('Flutter WebView example'),
// This drop down menu demonstrates that Flutter widgets can be shown over the web view.
        actions: <Widget>[
          NavigationControls(_controller.future),
          SampleMenu(_controller.future),
        ],
      ),
// We're using a Builder here so we have a context that is below the Scaffold// to allow calling Scaffold.of(context) so we can show a snackbar.
      body: Builder(builder: (BuildContext context) {
return WebView(
          initialUrl: '<https://flutter.dev>',
          javascriptMode: JavascriptMode.unrestricted,
          onWebViewCreated: (WebViewController webViewController) {
            _controller.complete(webViewController);
          },
          onProgress: (int progress) {
            print("WebView is loading (progress : $progress%)");
          },
          javascriptChannels: <JavascriptChannel>{
            _toasterJavascriptChannel(context),
          },
          navigationDelegate: (NavigationRequest request) {
if (request.url.startsWith('<https://www.youtube.com/>')) {
              print('blocking navigation to $request}');
return NavigationDecision.prevent;
            }
            print('allowing navigation to $request');
return NavigationDecision.navigate;
          },
          onPageStarted: (String url) {
            print('Page started loading: $url');
          },
          onPageFinished: (String url) {
            print('Page finished loading: $url');
          },
          gestureNavigationEnabled:true,
        );
      }),
      floatingActionButton: favoriteButton(),
