flutter_pan_select 1.0.0

Multi-select with drag-to-select (pan) gesture for grids and lists. Lightweight, themeable selection controller with marquee selection and auto-scroll support.

1.0.0

Initial release.

• SliverPannable<T>: the core pan-to-select sliver. Layout-agnostic, with edge auto-scroll that keeps extending the selection while the pointer holds still at the viewport edge.
• SliverPannableGrid<T>.builder / SliverPannableList<T>.separated: convenience wrappers over the native sliver layouts. Each item is wrapped with a default selection checkbox (SelectionItemOverlay for grids, SelectionLeftCheckbox for lists); pass checkboxBuilder to customise the decoration, or (_, _, child) => child to disable the wrapping.
• SelectionController<T>: selection state controller extending ChangeNotifier. Notifies only when the selection actually changes.
• SelectionScope<T>: an optional InheritedWidget that hosts a controller for a widget subtree.
• SelectionButton<T>: a one-tap toggle for selection mode (startSelection / endSelection).
• All widgets support both an explicit controller: parameter (similar to the TabController pattern) and a SelectionScope.of<T> fallback.
• Vertical scrolling only.
