If you want to use the standard Dialog you can just apply a Decoration to the Container that matches your Dialog settings

showDialog(
      context: context,
      child: Dialog(
        shape: RoundedRectangleBorder(borderRadius: BorderRadius.circular(10)),
        child: Column(
          children: [
            Container(
              decoration: BoxDecoration(     
                borderRadius: BorderRadius.only(topLeft: Radius.circular(10), topRight: Radius.circular(10)),
              ),          
              child: Text('foobar'),
            )
          ],
        ),
      ),
    );
