How to prevent ripple effect on surrounding InkWell when tapped on InkWell inside

Let's say that I have this widget:

Card(
  child: InkWell(
    onTap: () {},
    child: Padding(
      padding: const EdgeInsets.all(28.0),
      child: RaisedButton(
        child: Text('Test'),
        onPressed: () {},
      ),
    ),
  ),
),

I would like to disable (prevent showing) ripple effect on Card/InkWell only when the RaisedButton is tapped, but to show it when the Card is tapped (i.e. outside the button). Is there any way to achieve this effect?

I think the generalized question can be: How to prevent ripple effect on surrounding InkWell when tapped on InkWell inside? If you take a look at the source code then you can see that RaisedButton has Material and InkWell widgets that cause ripple.

Here is the full sample code.

If you want a quick hack, check it out:

Container(
  width: 180,
  height: 120,
  child: Stack(
    children: <Widget>[
      Card(
        child: InkWell(
          onTap: () {},
        ),
      ),
      Center(
        child: RaisedButton(
          child: Text('Test'),
          onPressed: () {},
        ),
      )
    ],
  ),
)

You can handle the logic inside onHighlightChanged method;

Color _color;

@override
Widget build(BuildContext context) {
  return Scaffold(
    appBar: AppBar(),
    body: Center(
      child: Card(
        child: InkWell(
          splashColor: _color,
          highlightColor: _color,
          onTap: () {},
          child: Padding(
            padding: const EdgeInsets.all(28.0),
            child: RaisedButton(
              onHighlightChanged: (value) {
                if (value) {
                  setState(() => _color = Colors.white);
                } else {
                  Timer(Duration(milliseconds: 200), () {
                    setState(() => _color = null);
                  });
                }
              },
              child: Text('Test'),
              onPressed: () {},
            ),
          ),
        ),
      ),
    ),
  );
}
