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

Properties

action → Widget?
The action shown on the navigation bar.
final
currentIndex → int?
The index of the currently active item.
final
dividerIndex → int?
The index of the item the divider should be displayed after.
final
hashCode → int
The hash code for this object.
no setterinherited
items → List<ZetaNavigationBarItem>
The items displayed on the navigation bar.
final
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
onTap → void Function(int value)?
Called when an item is tapped with the index of the tapped item.
final
rounded → bool?
Sets rounded or sharp border of the containing box and the icon style.
finalinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
semanticLabel → String?
Value passed to the Semantics widget.
final
shrinkItems → bool
When set to true the items will shrink to take up less space. This is useful when there are many items in the navigation bar. Defaults to false. When set to false the items will take up equal space and will expand to fill the bar.
final
splitItems → bool
Divides the navigation items in half.
final
useSafeArea → bool
Whether the child should be wrapped in a SafeArea.
final
