这对我来说很管用:

Material(
    color: Colors.white.withOpacity(0.0),
    child: InkWell(
      splashColor: Colors.orange,
      child: Text('Hello'), // actually here it's a Container wrapping an image
      onTap: () {
        print('Click');
      },
    ));

在这里尝试了很多答案后，我得出的答案是:

设置splashColor 在材质中包装InkWell(颜色:Colors.white.withOpacity(0.0)， ..)

感谢这里的答案让我明白了这两点

确保你没有在材质主题中添加以下属性:

(对我来说，这就是问题所在)

splashColor: Colors.transparent
splashFactory: NoSplash.splashFactory

eg:-

MaterialApp(
  home:......,
  theme: ThemeData(
    splashFactory: NoSplash.splashFactory, // Remove this
    splashColor: AppColors.transparent, // Remove this OR Change the color
    ......         
  ),
)

我遇到了一个类似的问题，将一个Inkwell添加到现有的复杂小部件中，用一个容器包装一个带有颜色的BoxDecoration。通过添加材质和墨水井，墨水井仍然被盒子装饰遮挡，所以我只是让盒子装饰的颜色稍微不透明，这样墨水井就能被看到

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,
            ),
          ),
        ),
      ),
    );
  }
}

循环部件的解决方案，如下所示:

Material(
    color: Colors.transparent,
    child: Container(
      alignment: Alignment.center,
      height: 100,
      child: Row(
        mainAxisAlignment: MainAxisAlignment.spaceAround,
        crossAxisAlignment: CrossAxisAlignment.center,
        children: [
          IconButton(
              enableFeedback: true,
              iconSize: 40,
              icon: Icon(
                Icons.skip_previous,
                color: Colors.white,
                size: 40,
              ),
              onPressed: () {}),
          IconButton(
            iconSize: 100,
            enableFeedback: true,
            splashColor: Colors.grey,
            icon: Icon(Icons.play_circle_filled, color: Colors.white, size: 100),
            padding: EdgeInsets.all(0),
            onPressed: () {},
          ),
          IconButton(
              enableFeedback: true,
              iconSize: 40,
              icon: Icon(
                Icons.skip_next,
                color: Colors.white,
                size: 40,
              ),
              onPressed: () {}),
        ],
      ),
    ),
  )

我认为给容器添加颜色是在掩盖墨水的效果

https://api.flutter.dev/flutter/material/InkWell/InkWell.html

这段代码似乎可以工作

  body: new Center(
    child: new Container(
      child: new Material(
        child: new InkWell(
          onTap: (){print("tapped");},
          child: new Container(
            width: 100.0,
            height: 100.0,
          ),
        ),
        color: Colors.transparent,
      ),
      color: Colors.orange,
    ),
  ),

只要点击中间的方块。

编辑:我找到了错误报告。https://github.com/flutter/flutter/issues/3782

This is actually as expected, though we should update the docs to make it clearer. 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. I have wanted to add a "MaterialImage" widget that conceptually prints its image into the Material as well so that then the splashes would be over the image. We could have a MaterialDecoration which does something similar for a Decoration. Or we could have Material itself take a decoration. Right now it takes a color, but we could extend that to taking a whole decoration. It's not clear whether it's really material-spec-compatible to have a material with a gradient, though, so I'm not sure whether we should do that. In the short run, if you just need a workaround, you can put a Material on top of the container, with the material set to use the "transparency" type, and then put the ink well inside that.

更新:Hixie去年合并了一个新的Ink解决方案。墨水提供了一种方便的方式溅在图像。

  testWidgets('Does the Ink widget render anything', (WidgetTester tester) async {
    await tester.pumpWidget(
      new Material(
        child: new Center(
          child: new Ink(
            color: Colors.blue,
            width: 200.0,
            height: 200.0,
            child: new InkWell(
              splashColor: Colors.green,
              onTap: () { },
            ),
          ),
        ),
      ),
    );


Material(
  color: Colors.grey[800],
  child: Center(
    child: Ink.image(
      image: AssetImage('cat.jpeg'),
      fit: BoxFit.cover,
      width: 300.0,
      height: 200.0,
      child: InkWell(
        onTap: () { /* ... */ },
        child: Align(
          alignment: Alignment.topLeft,
          child: Padding(
            padding: const EdgeInsets.all(10.0),
            child: Text('KITTEN', style: TextStyle(fontWeight: FontWeight.w900, color: Colors.white)),
          ),
        )
      ),
    ),
  ),
)

请注意:我没有测试新的墨水小部件。我从ink_paint_test中拷贝了代码。dart和Ink类文档
