Constructors

FPopover({required FPopoverController controller, required ValueWidgetBuilder<FPopoverStyle> followerBuilder, required Widget target, FPopoverStyle? style, Offset shift(Size, FPortalTarget, FPortalFollower) = FPortalFollowerShift.flip, bool hideOnTapOutside = true, String? semanticLabel, bool autofocus = false, FocusNode? focusNode, ValueChanged<bool>? onFocusChange, Alignment? followerAnchor, Alignment? targetAnchor, Key? key})
Creates a popover.

Properties

autofocus → bool
True if the follower will be selected as the initial focus when no other node in its scope is currently focused.
final
controller → FPopoverController
The controller that shows and hides the follower. It initially hides the follower.
final
focusNode → FocusNode?
An optional focus node to use as the focus node for the follower.
final
followerAnchor → Alignment
The anchor of the follower to which the targetAnchor is aligned to.
final
followerBuilder → ValueWidgetBuilder<FPopoverStyle>
The follower builder. The child passed to followerBuilder will always be null.
final
hashCode → int
The hash code for this object.
no setterinherited
hideOnTapOutside → bool
True if the popover is hidden when tapped outside of it. Defaults to true.
final
key → Key?

finalinherited
onFocusChange → ValueChanged<bool>?

final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
semanticLabel → String?
The follower's semantic label used by accessibility frameworks.
final
shift → Offset Function(Size, FPortalTarget, FPortalFollower)
The shifting strategy used to shift a follower when it overflows out of the viewport. Defaults to FPortalFollowerShift.flip.
final
style → FPopoverStyle?
The popover's style.
final
target → Widget
The target.
final
targetAnchor → Alignment
The anchor of the target to which the followerAnchor is aligned to.
