Methods

canAddToFoldWidget(int i, double offsetX, double screenW, FlowPaintingContext context, int lastIndex) → bool
getConstraintsForChild(int i, BoxConstraints constraints) → BoxConstraints
Override to control the layout constraints given to each child.
override
getFoldWidgetOffsetX(double foldWidgetWidth, double offsetX, double screenWidth) → double
getLineLimit(int lineLength) → bool
getSize(BoxConstraints constraints) → Size
Override to control the size of the container for the children.
override
needChangeToFoldWidget(int i, double offsetX, double screenW, int nowLine, FlowPaintingContext context) → bool
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
paintChildren(FlowPaintingContext context) → void
Override to paint the children of the flow.
override
shouldRelayout(covariant FoldWrapDelegate oldDelegate) → bool
Override this method to return true when the children need to be laid out. This should compare the fields of the current delegate and the given oldDelegate and return true if the fields are such that the layout would be different.
override
shouldRepaint(covariant FoldWrapDelegate oldDelegate) → bool
Override this method to return true when the children need to be repainted. This should compare the fields of the current delegate and the given oldDelegate and return true if the fields are such that paintChildren would act differently.
override
toMaxHeight(double oldMaxHeight, dynamic newMaxHeight) → double
toString() → String
Override this method to include additional information in the debugging data printed by debugDumpRenderTree and friends.

Operators

operator ==(Object other) → bool
The equality operator.
