AdaptiveGridLayout class
A widget for building declarative adaptive grid layouts based on screen size.
This widget uses a AdaptiveGridTemplate to define layout structure for different screen sizes and places children widgets into named regions.
Note on current implementation:
The current implementation uses a Stack and Positioned widgets to place
children based on calculated grid positions and spans. This is a basic
approximation. For true CSS Grid-like behavior (especially for FlexSize.content()
and advanced layout calculations), a custom RenderObjectWidget or
CustomMultiChildLayout with a robust MultiChildLayoutDelegate would be
required.
