WebviewScaffold widget in bordered container

I want to make rounded corner of my webview with your plugin but its not working correctly. Official Flutter plugin is working with rounded corner but official plugin not working when we use keyboard.
## System info

Issue occurs on: Android, iOS(Not having Mac)
Plugin version: 0.3.10+1
Flutter doctor output:

## Steps to Reproduce

My Code:

Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
backgroundColor: Colors.blue,
title: Text('Flutter'),
titleSpacing: 0.0,
),
body: Container(
margin: EdgeInsets.all(16.0),
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(12.0),
boxShadow: [BoxShadow(blurRadius: 2, color: Colors.red)]),
child: ClipRRect(
borderRadius: BorderRadius.circular(12.0),
child: WebviewScaffold(
url: 'https://flutter.dev/',
resizeToAvoidBottomInset: true,
),
),
),
);
}


```
```

```
```

```
```

Start by reproducing the supplied Scaffold, ClipRRect, and WebviewScaffold example with plugin version 0.3.10+1 on Android and iOS. Compare the bordered WebView and keyboard behavior with the stated official-plugin behavior; done means the rounded corners render correctly without losing the required keyboard behavior.
