Constructors
Creates a new ZetaNavigationBar.
ZetaNavigationBar.new({Key? key, bool? rounded, required List<ZetaNavigationBarItem> items, int? currentIndex, void onTap(int value)?, bool splitItems = false, int? dividerIndex, Widget? action, String? semanticLabel, bool shrinkItems = false, bool useSafeArea = true})
Creates a ZetaNavigationBar with an action.
ZetaNavigationBar.action({Key? key, bool? rounded, required List<ZetaNavigationBarItem> items, required Widget? action, int? currentIndex, void onTap(int value)?, String? semanticLabel, bool shrinkItems = false, bool useSafeArea = true})
Creates a ZetaNavigationBar with a divider after the item at the given index.
ZetaNavigationBar.divided({bool? rounded, Key? key, required List<ZetaNavigationBarItem> items, int? currentIndex, void onTap(int value)?, int? dividerIndex, String? semanticLabel, bool shrinkItems = false, bool useSafeArea = true})
Creates a ZetaNavigationBar and splits the items in half.
ZetaNavigationBar.split({bool? rounded, Key? key, required List<ZetaNavigationBarItem> items, int? currentIndex, void onTap(int value)?, int? dividerIndex, String? semanticLabel, bool useSafeArea = true})
