InkWell没有显示涟漪效应

点击容器触发onTap()处理程序，但不会显示任何墨水飞溅效果。

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

我试着把InkWell放在容器里，但徒劳。

当前回答

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

其他回答

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.

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,
 )

现在使用MaterialButton，在更新的版本颤振


Widget build(BuildContext context) {
    return Padding(
      padding: const EdgeInsets.symmetric(horizontal: 16.0),
      child: MaterialButton(
        child: Text(
          labelText,
          style: TextStyle(fontSize: 22),
        ),
        onPressed: () {},
        color: backgroundColor,
        height: 45,
        minWidth: double.infinity,
        shape: RoundedRectangleBorder(
          borderRadius: BorderRadius.all(
            Radius.circular(16),
          ),
        ),
      ),
    );
  }

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,
      ),
    ),
  ),
