WebviewScaffold rendered Outside the Container

Hi i need help: **Webviewscaffold** rendered outside the **Container**
I'm trying to load string text into a **WebviewScaffold**, but the webview is outside the container :

I tested with Text widget it worked well

```
_getDescription(description) {
return new Container(
child:
//new Text(description),
new WebviewScaffold(
url: new Uri.dataFromString(description, mimeType: 'text/html',encoding: utf8).toString()),
width: double.infinity,
margin: new EdgeInsets.only(top: 10.0),
height: 80,

);
}
```
the full Class:

```
child: new ListView(
children: [
new Hero(
tag: _title,
child: _getImageNetwork(Functions.getImgResizeUrl(_img,250,''))
),
_getBody(_title,_date,_description,_origin,context),
],
),

Widget _getBody(tittle,date,description,origin,context){

return new Container(
margin: new EdgeInsets.all(15.0),
child: new Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
_getTittle(tittle), //Text Widget
_getDate(date,origin), //Text Widget
_getDescription(description),
_getAntLink(),
_getLink(_link,context)
],
),
);
}
```
there is a warning in the Flutter WebView Plugin Docs :

> Warning: The webview is not integrated in the widget tree, it is a native view on top of the flutter view. you won't be able to use snackbars, dialogs ...

is this real reason of the problem?

Please Help!!

Reproduce the _getDescription WebviewScaffold inside the ListView and Container shown in the issue, comparing it with the working Text widget. Review the plugin documentation warning about the native view not being integrated into Flutter's widget tree. Done means determining whether the observed positioning is an inherent limitation and documenting the supported behavior or a concrete fix.
