Constructors

Hand({required double squareSize, bool stackPieces = true, BoardTheme theme = BoardTheme.blueGrey, required PieceSet pieceSet, List<String> pieces = const [], List<String> fixedPieces = const [], bool showCounts = true, BadgePosition? badgePosition, BadgeStyle badgeStyle = const badges.BadgeStyle(), MainAxisAlignment mainAxisAlignment = MainAxisAlignment.start, void onTap(String)?, void onDragStarted(String)?, void onDragCancelled(String)?, void onDragEnd(String, DraggableDetails)?, double dragFeedbackSize = 2.0, Offset dragFeedbackOffset = const Offset(0.0, -1.0)})
const

Properties

badgePosition → BadgePosition?
Position of piece count badges.
final
badgeStyle → BadgeStyle
The style of the piece count badges.
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 pieces being dragged will be multiplied by this. 1.5 is a good value for mobile, but 1.0 is preferable for web.
final
fixedPieces List<String>
A list of the piece types that should be fixed in the hand. These will always be present in the hand, in dulled form, even if there are no pieces of their type available.
final
hashCode int
The hash code for this object.
no setterinherited
key Key?
Controls how one widget replaces another widget in the tree.
finalinherited
mainAxisAlignment MainAxisAlignment
Alignment of piece widgets in the main row.
final
onDragCancelled → (void Function(String)?)
Called when a drag is cancelled.
final
onDragEnd → (void Function(String, DraggableDetails)?)
Called when a drag ends, i.e. it was dropped on a target.
final
onDragStarted → (void Function(String)?)
Called when a drag is started.
final
onTap → (void Function(String)?)
Called when the piece is tapped.
final
pieces List<String>
A list of the pieces in the hand. These should be single character piece symbols. Uppercase symbols will be white, lowercase ones will be black.
final
pieceSet PieceSet
The set of widgets to use for pieces on the board.
final
runtimeType Type
A representation of the runtime type of the object.
no setterinherited
showCounts bool
If true, the number of available pieces will be displayed in a small badge above each piece.
final
squareSize double
final
stackPieces bool
Whether to stack duplicate pieces, or lay them out individually.
final
theme BoardTheme
The theme to derive colours from.
final
