preview method
List<(EntityKind, GeometryPayload)>
preview(
- DraftDocument d,
- Handle group,
- Grip grip,
- Vector2 world,
What drag would draw, in world: the pieces a reshape preview paints,
computed once per pointer move, never per frame. Empty when there is
nothing to show. world is only read during the call.
Implementation
@override
List<(EntityKind, GeometryPayload)> preview(
DraftDocument d, Handle group, Grip grip, Vector2 world) =>
_of(d, group)?.preview(d, group, grip, world) ?? const [];
