如何使容器的边框在颤动中变成两种颜色？

Question

Flutter uses the two-colored warning Containers when a Renderflex is overflowing. However is it possible to color the border of a Container in that way in my flutter app?

Container(
  decoration: BoxDecoration(
    border: Border.all(color: Colors.yellow .... Colors.black)   <--- somehow (?)
  ),
  child: Text('My border')
}
