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

我可以通过使用Stack使我的情况工作。

Stack(
  children: [
    MyCustomWidget(), //              <--- Put this on bottom
    Material(
      color: Colors.transparent,
      child: InkWell(
        onTap: () {},
        child: Ink(
          width: 100,
          height: 100,
        ),
      ),
    ),
  ],
),

本页上的其他答案对我不起作用的原因是我的自定义小部件隐藏了墨水效果，而且我没有一个普通的图像(所以我不能使用ink .image)。

编辑:

你还是可以用墨的。图像，如果您将图像转换为正确的格式。

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

我已经找到了这个解决方法。我认为它可以帮助你:

Material(
      color: Theme.of(context).primaryColor,
      child: InkWell(
        splashColor: Theme.of(context).primaryColorLight,
        child: Container(
          height: 100,
        ),
        onTap: () {},
      ),
    )

颜色被赋予材质小部件。它是小部件的默认颜色。 你可以使用Inkwell的splashColor属性来调整波纹效果的颜色。

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
    ......         
  ),
)

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.
