Android 如何将Inkwell添加到Flatter中的容器文本中？

我是个新手。毫无疑问，这里的环境很棒。目前，我正在尝试创建一个多页面的应用程序在颤振与一些行和容器。我有两个这样的容器，它有一个文本

        Row(
          children: [
            Container(
              height: 50,
              width: MediaQuery.of(context).size.width / 1.2,
              decoration: BoxDecoration(
                borderRadius: BorderRadius.circular(20.0),
                color: ColorConstants.korangeColor,
              ),
              child: Center(
                child: Text(
                  "Food Poisoning Symptoms",
                  style: GoogleFonts.spartan(
                    fontSize: 15,
                    fontWeight: FontWeight.w600,
                    color: ColorConstants.kwhiteColor,
                  ),
                ),
              ),
            ),
            SizedBox(
              width: 10,
            ),
          ],
        ),

我确实用墨水瓶包装了我的容器，并尝试了以下方法：

      Row(
        children: [
          Container(
            height: 50,
            width: MediaQuery.of(context).size.width / 1.2,
            decoration: BoxDecoration(
              borderRadius: BorderRadius.circular(20.0),
              color: ColorConstants.korangeColor,
            ),
            child: Center(
              child: Text(
                  "Food Poisoning Symptoms",
                  style: GoogleFonts.spartan(
                    fontSize: 15,
                    fontWeight: FontWeight.w600,
                    color: ColorConstants.kwhiteColor,
                  ),
                ),
                InkWell(
                  onTap: () {
                    Navigator.push(
                      context,
                      MaterialPageRoute(
                        builder: (context) => FoodPoisoning(),
                      ),
                    );
                  },
                ),

            ),
          ),

但我的错误日志显示为黑屏，页面显示为黑屏：

断言失败：第1920行位置12：“hasSize”

我特别不明白我的代码发生了什么。有人能告诉我是什么问题以及如何解决吗？

用

InkWell

包装您的

容器

Row(children: [
      InkWell(
          onTap: () {
            Navigator.push(
              context,
              MaterialPageRoute(
                builder: (context) => FoodPoisoning(),
              ),
            );
          },
          child: Container(
            height: 50,
            width: MediaQuery.of(context).size.width / 1.2,
            decoration: BoxDecoration(
              borderRadius: BorderRadius.circular(20.0),
              color: ColorConstants.korangeColor,
            ),
            child: Center(
              child: Text(
                "Food Poisoning Symptoms",
                style: GoogleFonts.spartan(
                  fontSize: 15,
                  fontWeight: FontWeight.w600,
                  color: ColorConstants.kwhiteColor,
                ),
              ),
            ),
          ))
    ]);

用
InkWell
包装您的

Row(children: [
      InkWell(
          onTap: () {
            Navigator.push(
              context,
              MaterialPageRoute(
                builder: (context) => FoodPoisoning(),
              ),
            );
          },
          child: Container(
            height: 50,
            width: MediaQuery.of(context).size.width / 1.2,
            decoration: BoxDecoration(
              borderRadius: BorderRadius.circular(20.0),
              color: ColorConstants.korangeColor,
            ),
            child: Center(
              child: Text(
                "Food Poisoning Symptoms",
                style: GoogleFonts.spartan(
                  fontSize: 15,

                  color: ColorConstants.kwhiteColor,
                ),
              ),
            ),
          ))
    ]);

我通过创建一个无状态小部件来使用这个方法，该小部件与Flutter中的小部件不同

目标：是防止单击文本时阴影出现在容器大小上，如下所示：

class InkWellApp extends StatelessWidget {
  final Function onTap;
  final Widget child;

  final BorderRadius borderRadius;

  const InkWellApp(
      {Key key, this.onTap, this.child, this.borderRadius = BorderRadius.zero})
      : super(key: key);

  @override
  Widget build(BuildContext context) {
    return Stack(
      children: [
        child,
        Positioned.fill(
            child: Material(
          color: Colors.transparent,
          borderRadius: borderRadius,
          child: InkWell(
            borderRadius: borderRadius,
            onTap: onTap,
          ),
        )),
      ],
    );
  }
}

它的应用如下所示：

class _HomePageState extends State<HomePage> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Column(

        children: [
          .
          .
          .
          .

          InkWellApp(child: Text('Anything Text onTap .....'), onTap: (){
            /// onTap Function her ...
          },)
        ],

      ),

    );
  }
}

Row(
          mainAxisAlignment: MainAxisAlignment.center,
          children: [

            Container(
              height: 50,
              width: MediaQuery
                  .of(context)
                  .size
                  .width / 1.2,
              decoration: BoxDecoration(
                borderRadius: BorderRadius.circular(20.0),
                 color: ColorConstants.korangeColor,
              ),
              child: InkWell(
                onTap: () {
                  Navigator.push(
                    context,
                    MaterialPageRoute(
                      builder: (context) => FoodPoisoning(),
                    ),
                  );
                },
                child: Text(
                  "Food Poisoning Symptoms",
                  //Add this line instead of Center() widget
                  textAlign: TextAlign.center,
                  style: GoogleFonts.spartan(
                    fontSize: 15,
                    fontWeight: FontWeight.w600,
                    color: ColorConstants.kwhiteColor,
                  ),
                ),
              ),
            ),

          ],
