  }
  @override

    const data = [
      "taro", "jiro", "saburo",
    ];
    return Scaffold(
      appBar: AppBar(

      ),
      body: ListView.builder(
        itemCount: data.length,
        itemBuilder: (context, int index) {
          return InkWell(
            child: Card(
              child: Padding(
                child: Text(data[index],),
                padding: EdgeInsets.all(20.0),),
            ),
            onTap:
              _click,
          );
        },
