Constructors

CNNavigationBarAction({CNSymbol? icon, String? label, VoidCallback? onPressed, double? padding, double? labelSize, double? iconSize, Color? tint, String? badgeValue, Color? badgeColor}): Creates a navigation bar action item.
const
CNNavigationBarAction.fixedSpace(double width): Creates a fixed space item with specific width.
const
CNNavigationBarAction.flexibleSpace(): Creates a flexible space that expands to fill available space.
const
CNNavigationBarAction.popupMenu({CNSymbol? icon, String? label, required List<CNPopupMenuEntry>? popupMenuItems, required ValueChanged<int>? onPopupMenuSelected, double? padding, double? labelSize, double? iconSize, Color? tint, String? badgeValue, Color? badgeColor}): Creates a navigation bar action with a popup menu.
const
CNNavigationBarAction.popupMenuButton({CNSymbol? icon, String? label, required List<CNPopupMenuEntry>? popupMenuItems, required ValueChanged<int>? onPopupMenuSelected, double? padding, double? labelSize, double? iconSize, Color? tint, String? badgeValue, Color? badgeColor}): Creates a navigation bar action with a CNPopupMenuButton. This provides a more native-looking popup menu button with built-in styling.
const
CNNavigationBarAction.pullDownButton({CNSymbol? icon, String? label, required List<CNPopupMenuEntry>? popupMenuItems, required ValueChanged<int>? onPopupMenuSelected, double? padding, double? labelSize, double? iconSize, Color? tint, String? badgeValue, Color? badgeColor}): Creates a navigation bar action with a CNPullDownButton. This provides a native pull-down button that shows a menu below the button.
const
CNNavigationBarAction.segmentedControl({required List<String>? segmentedControlLabels, required int? segmentedControlSelectedIndex, required ValueChanged<int>? onSegmentedControlValueChanged, double? segmentedControlHeight, double? segmentedControlWidth, Color? tint, double? padding}): Creates a navigation bar action with a segmented control. This embeds a native UISegmentedControl/NSSegmentedControl in the navigation bar.
