UiSmartActionGroup class

Experimental inline action group for replacing "More" sheets with morphing buttons.

This renderer is geometry-first: every frame is solved as a list of exact button rectangles before any widgets are built. That keeps width, gaps, opacity, and hit testing coordinated and avoids transient Flex overflows.

Properties

actions → List<UiSmartActionGroupAction>
Ordered actions. The first collapsedCount stay visible while collapsed.
final
collapseButtonWidth → double?
Fixed wide-layout width for the expanded collapse control.
final
collapsedCount → int
Number of leading actions shown before the "more" control.
final
collapseIcon → Widget
Leading icon for the expanded collapse control.
final
collapseIntent → UiIntent
Intent for the expanded collapse control.
final
collapseLabel → String
Label for the expanded collapse control.
final
collapseOnAction → bool
Whether activating a non-toggle action collapses the group first.
final
compactBreakpoint → double
Below this width the group falls back to a horizontal scroll viewport.
final
curve → Curve?
Override transition curve. Defaults to theme standard curve.
final
duration → UiMotionDuration
final
expanded → bool?
Controlled expanded state. When null, the widget owns its state.
final
expandedLayout → UiSmartActionGroupExpandedLayout
Width policy once the hidden actions are shown in wide layouts.
final
hashCode → int
The hash code for this object.
no setterinherited
initiallyExpanded → bool
Initial uncontrolled expanded state.
final
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
moreButtonWidth → double?
Fixed wide-layout width for the collapsed overflow control.
final
moreIcon → Widget
Leading icon for the collapsed overflow control.
final
moreIntent → UiIntent
Intent for the collapsed overflow control.
final
moreLabel → String
Label for the collapsed overflow control.
final
onExpandedChanged → ValueChanged<bool>?
Called whenever the expanded state should change.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
semanticLabel → String?
Spoken label for the semantic group.
final
showCollapseAction → bool
Whether to append a collapse button when expanded.
final
size → UiSize
Button size applied to every action.
final
spacing → double?
Gap between buttons. Defaults to the token x2 spacing.
final
