FolderStack class

FolderStack继承于Stack(层叠布局)控件,新增了折叠屏悬停能力,通过识别upperItems自动避让折叠屏折痕区后移到上半屏

Inheritance

Constructors

FolderStack({Key? key, required List<String> upperItems, required List<Widget> children, ValueChanged<FoldStatus>? onFolderStateChange, VerticalDirection verticalDirection = VerticalDirection.down, AlignmentGeometry alignment = AlignmentDirectional.topStart, TextDirection? textDirection, StackFit fit = StackFit.loose, Clip clipBehavior = Clip.hardEdge})
const

Properties

alignment AlignmentGeometry
Same as Stack.alignment. relative to text direction.
final
children List<Widget>
Same as MultiChildRenderObjectWidget.children.
final
clipBehavior Clip
Same as Stack.clipBehavior. Defaults to Clip.hardEdge.
final
fit StackFit
Same as Stack.fit. (StackFit.expand).
final
hashCode int
The hash code for this object.
no setterinherited
key Key?
Controls how one widget replaces another widget in the tree.
finalinherited
onFolderStateChange ValueChanged<FoldStatus>?
当折叠状态改变的时候回调
final
runtimeType Type
A representation of the runtime type of the object.
no setterinherited
textDirection TextDirection?
Same as Stack.textDirection. Defaults to the ambient Directionality.
final
upperItems List<String>
定义悬停态会被移到上半屏的子组件的id,组件id在此数组中的子组件悬停触发时自动避让折叠屏折痕区后移到上半屏,其它组件堆叠在下半屏区域。
final
verticalDirection VerticalDirection
Same as Flex.verticalDirection.
