How can you determine the current coordinates of an object on a display?

In Flutter, to determine the current coordinates of a widget on the screen, you can use the RenderBox class and the localToGlobal method.

Example:

final RenderBox box = context.findRenderObject() as RenderBox;
final Offset position = box.localToGlobal(Offset.zero);
print('Widget position on screen: $position');

Here, context is the widget's BuildContext, and the position will be in global screen coordinates. This is useful, for example, for positioning tooltips or animations relative to the widget.
