C.3. What about using an absolute position?

To specify an absolute position for a widget as x-y coordinates, nest it in a Positioned widget that is itself nested in a Stack widget. Positioned gives you access to properties like top, left, right, and bottom, similar to CSS. Here’s an example:

// Stack and Positioned
Stack(                            1
  children: [
    Positioned(                   2
      child: Text("Lorem ipsum"),
      left: 24.0,
      top: 24.0,
    ),
    Text("Not positioned"),       3
  ],
),
