[Flutter]表示するリストを線で分ける

線を引きたい部分はDividerを使う

var resultList = List<Widget>();
   list.forEach((val) {
     resultList.add(
       Column(children: [
         Row(
           children: [
             Expanded(
               child: FlatButton(
                 child: Text(val.name),
                 onPressed: () async {
                   Navigator.push(
                       context,
                       MaterialPageRoute(
                           builder: (context) => HomePage()));
                 },
               ),
             ),
           ],
         ),
         Divider(
           color: Colors.grey,
         ),
       ]),
     );
   });
