letsar/flutter_staggered_grid_view

This system is a Flutter library that provides a comprehensive set of customizable grid layout widgets, including aligned, masonry, staggered, quilted, staired, and woven grid patterns. It enables developers to create complex, variable-sized, and multi-directional grid arrangements within scrollable views. The codebase includes rendering logic, layout delegates, and utility functions to support these diverse grid configurations.

Added a complete Flutter example application in the \examples/\ directory, including platform-specific configuration files for Android and iOS, along with Dart code that demonstrates various grid layouts: Aligned, Masonry, Quilted, Staggered, Staired, and Woven. The app features a home screen with menu entries for each layout type, allowing users to explore different grid configurations provided by the \flutter\_staggered\_grid\_view\ package.

The foundation layer now includes a new \constants.dart\ file defining \kZeroGeometry\ as an empty \SliverGridGeometry\, and a new \extensions.dart\ file providing a \findSmallestIndexWithMinimumValue\ method on \List\<num\>\. These additions provide reusable geometry constants and list utility functions for the rest of the application.

The library introduces new widget classes to support different 2D grid layouts. \AlignedGridView\ and \SliverAlignedGrid\ provide an aligned grid layout where each track has the main axis extent of the widest child. \MasonryGridView\ and \SliverMasonryGrid\ implement a masonry layout, placing children as close as possible to the start of the main and cross axes. \StaggeredGrid\ and \StaggeredGridTile\ allow for staggered arrangements where each child can have a different size. These widgets are designed to be used with \CustomScrollView\ or as standalone scrollable views.

Added new layout delegates for quilted, staired, and woven grid patterns. The quilted layout supports variable-sized tiles in a repeating pattern, the staired layout arranges tiles in a staggered, alternating direction, and the woven layout creates a complex interlaced pattern with customizable alignment and spacing. These new delegates extend the existing patterned grid infrastructure to support more complex and varied grid designs.

The rendering layer in \lib/src/rendering\ has been expanded with new classes to support more complex grid and track-based layouts. \RenderSliverMasonryGrid\ and \SliverSimpleGridDelegate\ are introduced to handle Masonry-style layouts where children are placed as close as possible to the start of the main and cross axes. \RenderStaggeredGrid\ and \StaggeredGridDelegate\ are added to support staggered grid layouts where children can have different sizes. Additionally, \RenderUniformTrack\ is added to lay out children in a uniform track with a fixed division. These changes enable the library to support Masonry, Staggered, and Uniform Track layout modes.

The library now exports additional grid layout types, specifically quilted, staired, and woven, alongside the existing aligned and masonry grids. Users can now utilize these new layout styles and their corresponding Sliver and standard widgets (e.g., SliverStaggeredGrid, AlignedGrid) for more flexible grid arrangements.

This release updates the package to version 0.7.0, which raises the minimum required Flutter version to 3.7.0 and resolves a deprecation warning related to Scrollable.of. The change also includes updated project metadata, a .pubignore file to exclude build and example directories from the published package, and a comprehensive CHANGELOG documenting the history of layout fixes and features.

(repo-wide) · high confidence

Added comprehensive test coverage for the staggered grid view library, including unit and widget tests for the quilted, staired, and woven layout delegates, as well as the AlignedGridView, MasonryGridView, StaggeredGrid, StaggeredGridTile, and UniformTrack components. These tests verify correct layout sizing, positioning, and scroll offset calculations for various grid configurations.
