尝试这样的事情:

@override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(backgroundColor: Colors.orange),
      body: ListTile(
        trailing: Row(
          mainAxisSize: MainAxisSize.min,
          children: <Widget>[
            Container(
              width: 1,
              height: 24,
              color: Colors.grey,
            ),
            SizedBox(width: 10),
            Icon(
              Icons.notifications,
              color: Colors.grey,
              size: 19,
            )
          ],
        ),
      ),
    );
  }
