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.

-
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.
