dnd_kit 0.3.1

Pure Dart core engine for the dnd_kit drag-and-drop family. Flutter apps use dnd_kit_flutter; Jaspr apps use dnd_kit_jaspr.

Changelog

0.3.1

• Adds DndAnnouncements to the shared engine as a framework-neutral accessibility contract for drag start/over/end/cancel announcements.
• Flutter and Jaspr adapters now reuse the shared contract from dnd_kit instead of maintaining duplicate pure-Dart announcement builders.

0.3.0

• Package identity change. dnd_kit is now the pure Dart core engine of the toolkit — the package formerly published as dnd_kit_core. The API surface is unchanged from dnd_kit_core 0.2.0-dev.0; only the package name and import path changed (package:dnd_kit_core/dnd_kit_core.dart → package:dnd_kit/dnd_kit.dart).
• The earlier dnd_kit 0.1.x releases were the Flutter umbrella that re-exported dnd_kit_flutter. That umbrella role is discontinued: Flutter apps now depend on dnd_kit_flutter and import package:dnd_kit_flutter/dnd_kit_flutter.dart; Jaspr apps depend on dnd_kit_jaspr. Both adapters build on this engine.
• dnd_kit_core is discontinued and superseded by this package. See ADR 0017 for the rationale and the brand-as-core decision that supersedes ADR 0014.
• Adds additive axis-aware shared auto-scroll math via DndScrollAxis and an axis parameter on dndAutoScrollVelocity(...). Vertical behavior remains the default; both the Flutter and Jaspr adapters now execute against this contract.

0.2.0-dev.0

• Starts the shared-runtime development line for dnd_kit_core.
• Adds DndRuntime as the framework-neutral drag engine shared by the Flutter and Jaspr adapters.
• Moves DndMeasuringRegistry and its measurement-status contract into core so adapters can share the same measuring cache model.
• Moves DndPointerSensor to core on top of DndRuntime, preserving the pointer-activation state machine across adapters.
• Brings the shared sortable move/strategy math and auto-scroll edge/velocity math into core for reuse outside Flutter.

0.1.0

• First public release of the pure Dart engine: stable identifiers, geometry, drag state and events, collision detectors, modifiers, sensor and registry contracts, and diagnostics.
• DndRegistry.registerDraggable/registerDroppable and their unregister counterparts accept an optional owner. Owner-aware registration is last-wins and lets a new owner take over an id without tripping duplicate detection — required so draggables in a lazy ListView.builder survive the list rebuilding a keyed entry (new element mounts before the old is disposed). A departing owner can no longer remove a registration that a newer owner already took over.
• Owner-aware entries now also keep per-id owner claims and emit a deferred duplicate warning when multiple owners still claim the same id after reconciliation. This restores actionable duplicate diagnostics for owner-registered entries without reintroducing the lazy-list remount crash.
• Calls without owner keep the strict duplicate-id debug assertion and immediate warning behavior for direct DndRegistry usage.

0.1.0-dev.1

• Added a package-local example/example.md so pub.dev can render a compact illustrative pure Dart example for the package.

0.1.0-dev.0

• Initial development release of the pure Dart dnd_kit_core package.
• Includes stable ID, geometry, drag state, drag event, collision detector, modifier, sensor, registry, and diagnostics primitives.
• Keeps Flutter, dart:ui, widget, render object, gesture, overlay, and app state-management dependencies out of the core package.
