我想在 flutter 中将自定义 webview 添加到 sizedBox ......我已经尝试过这样做，但有一个错误：

代码：

@override
   Widget build(BuildContext context) {   
    SystemChrome.setEnabledSystemUIOverlays([SystemUiOverlay.bottom]);
    return new Scaffold(
      key: _scaffoldKey,
         floatingActionButton: new Row(
        mainAxisSize: MainAxisSize.min,
            children: <Widget>[
                new GestureDetector(
                  child: new Image.network("http://modernworfare.altervista.org/pause.png", width: 80.0,),
                  onTap: (){stop(); _showSnackBar();}, 
                ),
                new GestureDetector(
                  child: new Image.network("http://modernworfare.altervista.org/bg.png",width: 80.0,),
                  onTap: (){play(); _showSnackBar2();},

        children: <Widget>[
        new Column(
        children: <Widget>[
          new Image.network("https://scontent-mxp1-1.xx.fbcdn.net/v/t1.0-9/16864236_1836092593321492_1828236030296093399_n.jpg?_nc_cat=0&oh=817190c0ef6ac6e3076582905997f3e9&oe=5B81BFF9"),
          new Divider(),
          new Row(
            mainAxisAlignment: MainAxisAlignment.spaceEvenly,
            children: <Widget>[
              new Container(
              padding: new EdgeInsets.all(8.0),
