Properties

autofocus → bool?
True if this widget will be selected as the initial focus when no other node in its scope is currently focused.
final
barrierSemanticsDismissible → bool
Whether the barrier semantics are included in the semantics tree. Defaults to true.
final
barrierSemanticsLabel → String?
The popover's barrier label used by accessibility frameworks.
final
builder → ValueWidgetBuilder<FPopoverController>
An optional builder which returns the child widget that the popover is aligned to.
final
cacheExtent → double?
The scrollable area's cache extent in logical pixels.
final
child → Widget?
The child.
final
childAnchor → AlignmentGeometry
The anchor point on the child used for positioning relative to the menuAnchor.
final
control → FPopoverControl
Defines how the popover menu's shown state is controlled.
final
cutout → bool
Whether the barrier should exclude the builder/child's area using a non-interactive cutout.
final
cutoutBuilder → void Function(Path path, Rect bounds)
{@macro forui.foundation.FModalBarrier.cutoutBuilder}
final
divider → FItemDivider
The divider between tiles.
final
dragStartBehavior → DragStartBehavior
Determines the way that drag start behavior is handled. Defaults to DragStartBehavior.start.
final
focusNode → FocusScopeNode?
An optional focus node to use as the focus node for this widget.
final
groupId → Object?
An optional group ID that groups TapRegions together so that they operate as one region. If a tap occurs outside of all group members, then group members that are shown will be hidden.
final
hashCode → int
The hash code for this object.
no setterinherited
hideRegion → FPopoverHideRegion
The region that can be tapped to hide the popover.
final
intrinsicWidth → bool
Whether the menu should intrinsically size to the widest child. Defaults to true.
final
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
maxHeight → double
The max height, in logical pixels. Defaults to infinity.
final
The anchor point on the menu used for positioning relative to the childAnchor.
final
offset → Offset
Additional translation to apply to the popover's position.
final
onFocusChange → ValueChanged<bool>?
Handler called when the focus changes.
final
onTapHide → VoidCallback?
A callback that is called when the popover is hidden by tapping outside of it.
final
overflow → FPortalOverflow
The callback used to shift a popover when it overflows out of the viewport.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
scrollController → ScrollController?
The scroll controller used to control the position to which this group is scrolled.
final
semanticsLabel → String?
The menu's semantic label used by accessibility frameworks.
final
spacing → FPortalSpacing
The spacing between the popover and child anchors.
final
style → FPopoverMenuStyleDelta
The popover menu's style.
final
traversalEdgeBehavior → TraversalEdgeBehavior?
Controls the transfer of focus beyond the first and the last items in a popover. Defaults to TraversalEdgeBehavior.closedLoop.
final
useViewInsets → bool
Whether to avoid the platform view's insets (the soft keyboard).
final
useViewPadding → bool
Whether to avoid the platform view's padding (static safe areas like the notch and status bar).
final
