Properties
child → Widget
A widget that represents the piece.
final
dragFeedbackOffset → Offset
A vector to offset the position of dragged pieces by, relative to the size of the piece.
No offset is recommended for web, and Offset(0,-1) for mobile, in which case
the bottom of the piece will be anchored to the finger.
final
dragFeedbackSize → double
The size of the piece being dragged will be multiplied by this.
1.5 is a good value for mobile, but 1.0 is preferable for web.
final
draggable → bool
Whether the piece on this square can be dragged.
final
hashCode → int
The hash code for this object.
no setter inherited
interactible → bool
Whether the piece can be interacted with.
This must be false when any other piece is being dragged, to avoid
the GestureDetector absorbing the drag.
final
key → Key ?
Controls how one widget replaces another widget in the tree.
final inherited
move → PartialMove
A single-character symbol representing the piece of the square. e.g. 'N', 'k'.
final
onDragCancelled → VoidCallback ?
Called when a drag is cancelled.
final
onDragEnd → (void Function(DraggableDetails ?)
Called when a drag ends, i.e. it was dropped on a target.
final
onDragStarted → VoidCallback ?
Called when a drag is started.
final
onTap → VoidCallback ?
Called when the piece is tapped.
final
runtimeType → Type
A representation of the runtime type of the object.
no setter inherited
