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.

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
    ......         
  ),
)

更好的方法是使用Ink小部件而不是其他小部件。

而不是在容器内定义颜色，你可以在墨水小部件本身中定义它。

下面的代码将工作。

Ink(
  color: Colors.orange,
  child: InkWell(
    child: Container(
      width: 100,
      height: 100,
    ),
    onTap: () {},
  ),
)

不要忘记在InkWell中添加onTap:(){}，否则它会 也没有显示出涟漪效应。

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。

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)),
          ),
        )
      ),
    ),
  ),
)
