ref: https://drafts.csswg.org/css-backgrounds/#shadow-layers

The priority in which the layers are expressed is from the one in front. That is, what was written first is expressed at the top of the layer.

css multiple shadows are supported, separated by commas.

ex

box-shadow: 12px 12px 2px 1px rgba(0, 0, 255, 0.2), 5px -1px 2px 1px rgb(59, 0, 19);

flutter

Unlike css, the priority in which layers are expressed is from the back.

  BoxShadow(
    offset: Offset(10.0, 10.0),

    color: Color.fromARGB(255, 103, 90),
    spreadRadius: 5.0,
  ),
  BoxShadow(
    offset: Offset(9.0, 6.0),
