MasonryLayout class

A responsive masonry layout that displays items with variable heights in columns

This widget implements a Pinterest-style layout where items flow vertically with consistent column widths but varying heights. The layout automatically adjusts column count based on available space and the specified maximum item width.

Features:

  • Dynamic column count based on screen width
  • Efficient rendering with lazy loading
  • Smooth scrolling in both directions
  • Automatic content flow between columns

Example usage:

MasonryLayout(
  maxCrossAxisExtent: 200,
  scrollDirection: Axis.vertical,
  children: myWidgets,
)
