LayoutSize class

the layout result of RenderSLidable size is the size of SlidablePanel.child hasPreAction indicates whether there has SlideActionPanel at ActionPosition.pre hasPostAction indicates whether there has SlideActionPanel at ActionPosition.post

final

Methods

getDragExtent(double ratio) → double

calculate the final drag extent after animating ends so that the next dragging could start from the previous drag extent

getOpenTarget(ActionPosition position) → double?

calculate the target ratio when we want to open the panel at position if there is no SlideActionPanel at position, return null

getRatio(double dragExtent) → double?

if no SlideActionPanel, return null by doing so, we could disable sliding if no actions along the axis the ratio would be calculated: dragExtent / slidable space along the axis the slidable space is calculated by maxSlideThreshold * the space along the axis

getToggleTarget(SlideDirection direction, double ratio, bool isForward) → double

according to direction, ratio and isForward calculate the target ratio when we should continue to slide after dragging ends

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool
