FlexibleWidgetExtension extension

Extension methods for Widget that provide convenient flexible layout functionality.

This extension adds methods to easily wrap widgets in Flexible widgets for flexible layout control within Row, Column, and Flex widgets. All methods return new Flexible widgets without modifying the original widget.

The extension provides both flexible control (flex) and convenient shortcuts for common flex values (flex2, flex3, etc.) with different FlexFit options.

Unlike Expanded, Flexible widgets can occupy less than the available space if their child doesn't need it all, depending on the FlexFit setting:

• FlexFit.loose: Child can be smaller than the allocated space
• FlexFit.tight: Child must fill the allocated space (like Expanded)

Example usage:

Row(
  children: [
    Text('Flexible').flex(),           // Takes needed space, up to 1 part
    Text('Tight').flexTight(2),        // Forces 2 parts of space
    Text('Loose').flexLoose(1),        // Up to 1 part, but can be smaller
  ],
);
