Constructors

BoardTargets({Key? key, BoardSize size = BoardSize.standard, int orientation = Squares.white, dynamic onTap(int)?, bool validateDrag(PartialMove, int)?, void acceptDrag(PartialMove, int)?, void onDragLeave(PartialMove, int)?, DragTargetFeedback? feedback})

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)?)
Called when a piece moves over a new square. This includes external pieces, such as those that came from hands.
