Properties

alignment → AlignmentGeometry
The alignment of the child within the ClipRect wrapping it.
final
axis → CollapsibleAxis
The axes the widget will collapse/expand along.
final
child → Widget
The components contained within the sub-menu.
final
clipBehavior → Clip
The clipping behavior applied to the ClipRect that wraps the child.
final
collapsed → bool
The state of the sub-menu, whether it's visible or not.
final
curve → Curve
The easing curve applied to the collapsing/expanding animation.
final
duration → Duration
The duration of the collapsing/expanding animation.
final
fade → bool
If true, the child will fade in/out during the collapsing/expanding animation.
final
hashCode → int
The hash code for this object.
no setterinherited
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
maintainAnimation → bool
If false, the child and its sub-tree's animation tickers, if it has any, will be paused when in the collapsed state, if true, they will continue running.
final
maintainState → bool
If false, the child will be replaced with a SizedBox.shrink() when the Collapsible is in its collapsed state, if true, the child will remain built when collapsed.
final
minHeightFactor → double
The value the height of the child is multiplied by when the widget is in its collapsed state.
final
minOpacity → double
If fade is true, the opacity will be transitioned to minOpacity when the widget is in its collapsed state.
final
minWidthFactor → double
The value the width of the child is multiplied by when the widget is in its collapsed state.
final
onComplete → VoidCallback?
A callback called every time the animation completes.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited

Methods

inherited
toStringShort() → String
A short, textual description of this widget.
