Steps to Reproduce

Follow the page https://codelabs.developers.google.com/codelabs/flutter/index.html#5

my code is :

```
Widget _setupBody() {
return new Column(
children: [
new Expanded(
child: new ListView.builder(
itemBuilder: (_nothing, int index) => _messageList[index],
reverse: true,
itemCount: _messageList.length,
),
),
new Divider(height: 1.0),
new Container(
padding: const EdgeInsets.symmetric(horizontal: 5.0),
//decoration: new BoxDecoration(color: Theme.of(context).cardColor,),
child: new Row(
children: [
new Flexible(
child: new TextField(
maxLines: 1,
controller: _myController,
onSubmitted: _handleSubmitt,
decoration: new InputDecoration.collapsed(hintText: "input here"),
),
),
new IconTheme(
data: new IconThemeData(color: Theme.of(context).accentColor),
child: new IconButton(icon: new Icon(Icons.send), onPressed: () => _handleSubmitt(_myController.text)))
],
))
],
);
}

then it shown like this:

after add the decoration  (uncomment the line 14)

as you see, the boxdecoration hide the ripple.

from the code , i think , the boxdexcoration should be rendered first. 

How to change the code makes the ripple at front of the boxdexcoration?

hey @cjztool, you can wrap it into a Material class instead of using Container class if you just want to color it.
