如果你想在任何小部件上产生涟漪效应，只需:

1-用材料和墨水包装小部件。

2-设置颜色小部件从材料。

3-永远不要为你想让它起波纹的小部件设置颜色。

   Material (
   color: const Color(0xcffFF8906),
   child: InkWell(
   ontap:() { },
   child: Container(
   color: Colors.transparent,
   height: 80,
   width: 80,
 )

I ran into this same problem trying to create an alternating color of InkWell's in a ListView. In that particular case, there's a simple solution: wrap the alternates in a Container that uses a mostly transparent tint/brightness change -- the InkWell touch animation will still be visible beneath it. No Material needed. Note there are other issues when trying to work around this with a Materal -- e.g., it will override a DefaultTextStyle you're using with the default (it installs an AnimatedDefaultTextStyle) which is a huge pain.

为材质添加透明颜色在我的案例中起作用:

  child: new Material(
    color: Colors.transparent
    child: new InkWell(
      onTap: (){},
      child: new Container(
        width: 100.0,
        height: 100.0,
        color: Colors.amber,
      ),
    ),
  ),

用材料包裹InkWell，然后使用你需要的颜色:

class _MyHomePageState extends State<MyHomePage> {
  @override
  Widget build(BuildContext context) {
    return new Scaffold(
      appBar: new AppBar(
        title: new Text(widget.title),
      ),
      body: new Center(
        child: Material(
          color: Colors.orange,
          child: new InkWell(
            onTap: (){ print("tapped"); },
            child: new Container(
              width: 100.0,
              height: 100.0,
            ),
          ),
        ),
      ),
    );
  }
}

添加onTap:(){}监听器后，涟漪效应应该工作良好。如果你在InkWell()小部件中使用BoxShadow()，它就不工作了。

用简单的话快速解决:

此解决方案适用于小部件树的任何位置。 只需在InkWell之前添加额外的材质，如下所示:

return Container(
  .......code.......
  ),
  child: Material(
    type: MaterialType.transparency,
    child: InkWell(
      onTap: () {},
      child: Container(
        .......code.......
      ),
    ),
  ),
);
