PositionedWidgetExtensions extension

Extension methods for Widget that provide convenient positioning functionality within Stack widgets.

This extension adds methods to easily wrap widgets in Positioned widgets for precise positioning within Stack layouts. All methods return new Positioned widgets without modifying the original widget.

The extension provides both comprehensive positioning control (positioned) and convenient shortcuts for individual edge positioning (positionedTop, positionedLeft, etc.).

Important: Positioned widgets can only be used as direct children of Stack widgets. Using them outside of a Stack will cause a runtime error.

Example usage:

Stack(
  children: [
    Container(color: Colors.blue).positioned(left: 10, top: 20),
    Text('Overlay').positionedTop(50).positionedRight(30),
  ],
);
