bento_layout

Added

• Exported SkylinePacking, BentoLayoutDetails, and BentoGridLayout — consumers can now call SkylinePacking.pack() directly to compute tile geometry and position children in a Stack or custom layout, without going through SliverGrid
• TileEdge class and sortedEdges on BentoLayoutDetails — pre-sorted tile vertical spans for efficient scroll-offset lookups
• BentoGridLayout now uses O(log n) binary search for getMinChildIndexForScrollOffset and getMaxChildIndexForScrollOffset instead of returning the full item range — only visible tiles are built during scroll when using SliverGrid

Fixed

• BentoGridLayout.getMinChildIndexForScrollOffset and getMaxChildIndexForScrollOffset previously returned 0 and length - 1 for all scroll offsets, causing Flutter to build every tile on every scroll frame regardless of visibility

Changed

• Updated demo GIFs links in README

Changed

• Updated README with example screenshots and demo GIFs

Initial release.

Added

• BentoGrid — drop-in scrollable grid widget powered by the skyline algorithm
• BentoItem — tile wrapper accepting any Widget child and a BentoItemSize
• BentoItemSize — 9-value enum encoding both width and height in a self-documenting name (quarterBar, halfCard, fullTower etc.)
• BentoDimension — resolved tile dimensions as widthFraction + heightSpan
• BentoSizingStrategy — abstract interface for custom size mappings
• DefaultBentoSizingStrategy — built-in 3×3 size matrix (quarter/half/full × Bar/Card/Tower)
• BentoGridDelegate — exported SliverGridDelegate for composing the grid into custom CustomScrollView scroll views alongside other slivers

Design decisions

• Tile widths expressed as fractions of total width — no column count required
• Tile heights use a fixed unitHeight (default 180px) decoupled from width — heights are consistent across all screen sizes
• Skyline slot granularity derived automatically from the smallest widthFraction present in the item list
• Greedy bin-packing — items are placed at the lowest available position in order, preserving intentional tile sequence
