AbsoluteResizablePaneController class

Controller for resizable panes with absolute (fixed) sizing.

Manages a panel with a specific pixel size that can be adjusted through dragging or programmatic control. Size is maintained as an absolute value.

Example:

final controller = AbsoluteResizablePaneController(200);

ResizablePane(
  controller: controller,
  child: Container(color: Colors.blue),
)
