Properties
- acceptDrag → (void Function(PartialMove, int)?)
-
Called when a square accepts a piece dragged onto it.
final
- feedback → DragTargetFeedback?
-
Builds feedback for squares being hovered over by a dragged piece.
final
- hashCode → int
-
The hash code for this object.
no setterinherited
- key → Key?
-
Controls how one widget replaces another widget in the tree.
finalinherited
- onDragLeave → (void Function(PartialMove, int)?)
-
Called when a draggable leaves a square.
final
- onTap → (dynamic Function(int)?)
-
Called when a square is tapped.
Note that if a piece is above this square, it will absorb the tap, so both
onTap functions need to be handled.
final
- orientation → int
-
Determines which way around the board is facing.
0 (white) will place the white pieces at the bottom,
and 1 will place the black pieces there.
final
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- size → BoardSize
-
Dimensions of the board.
final
- validateDrag → (bool Function(PartialMove, int)?)
