      padding: const EdgeInsets.all(16),
      decoration: BoxDecoration(
        color: Colors.red[400],
      ),

Manipulating position and size

The following examples show how to perform more complex operations
on widget position, size, and background.

Setting absolute position

By default, widgets are positioned relative to their parent.

To specify an absolute position for a widget as x-y coordinates,
nest it in a Positioned widget that is,
in turn, nested in a Stack widget.
