WidgetListController class

WidgetListController Utility class for building children widgets with flexible spacing.

The BuildChildrenFlexGap class provides a convenient way to manipulate and process a list of child widgets, applying flexible spacing and layout modifications based on specified parameters. It encapsulates functionality for adding spacing, flexible spaces, and other layout adjustments to a list of widgets.

Parameters:

• children: The list of child widgets to be processed and manipulated.
• axis: The axis (horizontal or vertical) along which to apply spacing and layout modifications.
• startSpacerIndex: The index at which to add a flexible space widget (if applicable).
• globalSpace: The amount of global spacing to be applied between elements.

Example usage:

BuildChildrenFlexGap builder = BuildChildrenFlexGap(
  children: childrenList,
  axis: Axis.horizontal,
  startSpacerIndex: 1,
  globalSpace: 10.0,
);
List<Widget> processedChildren = builder.withGlobalSpace();
