flutter webview scroll 안되는 경우 gestureRecognizers: gestureRecognizers, 추가 해서 되었다

  final Set<Factory> gestureRecognizers = [Factory(() => EagerGestureRecognizer())].toSet();<b></b></i>

    return new Scaffold(

      //   title: appTitle,

      body: new NestedScrollView(

        headerSliverBuilder: (BuildContext context, bool innerBoxIsScrolled) {

          return <Widget>[

            headerNavCal(context),

          ];

        },

        // controller: _scrollController,

        body: Builder(builder: (BuildContext context) {

          return WebView(

            initialUrl: 'https://www.naver.com/',

            javascriptMode: JavascriptMode.unrestricted,

           <b> gestureRecognizers: gestureRecognizers,<i></i></b>

          );

        })

      ),

      //bottomNavigationBar: bottomBar(),

      backgroundColor: Colors.white,

    );
