Flutter: Inkwell does not work with Card

Question

I am trying to implement and inkWell wrap on a card widget, but it does not work at all. I am leaving on tap as null because this class takes 3 arguments that I populate later on to generate multiple cards. I cannot see what is going on that is preventing InkWell from rippling, so any help would be appreciated.

class FeedBackCardsImage extends StatelessWidget {   final String imagePath;   final String cardTitle;   final String cardTag;    FeedBackCardsImage({     this.imagePath,     this.cardTitle,     this.cardTag,   });    @override   Widget build(BuildContext context) {        return InkWell(           child: new Container(             child: new Card(               child: new Padding(                 padding: new EdgeInsets.all(15.0),                 child: new Column(                   children: <Widget>[                     new SizedBox(                       height: 184.0,                       child: new Stack(                         children: <Widget>[                           new Positioned.fill(                             child: new Image.asset(                               imagePath,                               //package: destination.assetPackage,                               fit: BoxFit.contain,                             ),                           ),                         ],                       ),                     ),                     new Padding(                       padding: new EdgeInsets.all(                         7.0,                       ),                       child: new Text(                         cardTitle,                         style: new TextStyle(                             fontSize: 14.0,                             fontWeight: FontWeight.w600,                             color: Colors.black87),                       ),                     ),                     new Padding(                       padding: new EdgeInsets.all(                         0.0,                       ),                       child: new Text(                         cardTag,                         style: new TextStyle(                             fontSize: 12.0,                             fontWeight: FontWeight.w400,                             color: Colors.black54),                       ),                     ),                   ],                 ),               ),             ),           ),         onTap: null,        );      }

Explanation :

"What's going on is that the Material spec says that the splashes are actually ink on the Material. So when we splash, what we do is we literally have the Material widget do the splash. If you have something on top of the Material, we splash under it, and you can't see it."

Workaround :

return Stack(children: <Widget>[             new Card(               child: new Padding(                 padding: new EdgeInsets.all(15.0),                 child: new Column(                   children: <Widget>[                     new SizedBox(                       height: 184.0,                       child: new Stack(                         children: <Widget>[                           new Positioned.fill(                             child: new Image.asset(                               imagePath,                               //package: destination.assetPackage,                               fit: BoxFit.contain,                             ),                           ),                         ],                       ),                     ),                     new Padding(                       padding: new EdgeInsets.all(                         7.0,                       ),                       child: new Text(                         cardTitle,                         style: new TextStyle(                             fontSize: 14.0,                             fontWeight: FontWeight.w600,                             color: Colors.black87),                       ),                     ),                     new Padding(                       padding: new EdgeInsets.all(                         0.0,                       ),                       child: new Text(                         cardTag,                         style: new TextStyle(                             fontSize: 12.0,                             fontWeight: FontWeight.w400,                             color: Colors.black54),                       ),                     ),                   ],                 ),               ),             ),             new Positioned.fill(                 child: new Material(                     color: Colors.transparent,                     child: new InkWell(                       onTap: () => null,                     )))           ]);
