Border radius of container inside card

Question

When I try to set the border radius of the top two corners of my container that is nested inside a card, the whole content of the container goes disappears. Here is my code, if you uncomment the commented line your whole content inside the container will go away.

Widget build(BuildContext context) {
    return Card(
      shape: RoundedRectangleBorder(
        borderRadius: BorderRadius.circular(5.0),
      ),
      margin: new EdgeInsets.symmetric(horizontal: 10.0, vertical: 6.0),
      child: Container(
        decoration: BoxDecoration(
          border: new Border(
              top: BorderSide(
            color: Theme.of(context).primaryColor,
            width: 3.0,
          )),
          //borderRadius: BorderRadius.only(topLeft: const Radius.circular(5.0)),
        ),
        child: makeListTile(widget.flight),
      ),
    );

}
