harmony 鸿蒙NavDestination
NavDestination
NavDestination is the root container of a destination page and represents the content area of the Navigation component.
NOTE
This component is supported since API version 9. Updates will be marked with a superscript to indicate their earliest API version.
Since API version 11, this component supports the safe area attribute by default, with the default attribute value being expandSafeArea([SafeAreaType.SYSTEM], [SafeAreaEdge.TOP, SafeAreaEdge.BOTTOM]). You can override this attribute to change the default behavior. In earlier versions, you need to use the expandSafeArea attribute to implement the safe area feature.
The NavDestination component must be used in conjunction with the Navigation component to act as the root node for the navigation destination page. When used alone, it can only function as a standard container component and does not possess any routing-related attributes or capabilities.
If the lifecycle of a page in the middle of the navigation stack changes, the lifecycle of the destination page at the top of the stack before the transition (onWillShow, onShown, onHidden, onWillDisappear) and the lifecycle of the destination page after the transition (onWillShow, onShown, onHidden, onWillDisappear) are both triggered at the end.
If no main title or subtitle is set for NavDestination and there is no back button, the title bar is not displayed.
Child Components
Built-in components and custom components are allowed, with support for (if/else, ForEach, and LazyForEach) rendering control.
Number of child components: multiple.

bindToScrollable14+
bindToScrollable(scrollers: Array<Scroller>)
Binds the NavDestination component with a scrollable container, which can be a List, Scroll, Grid, or WaterFlow component. This way, scrolling in the scrollable container triggers the display and hide animations of the title bar and toolbar of all NavDestination components that are bound to it – scrolling up triggers the hide animation, and scrolling down triggers the show animation. A single NavDestination component can be bound to multiple scrollable containers, and a single scrollable container can be bound to multiple NavDestination components. For details, see Example 1.
NOTE
- The connection between the scrolling actions and the animations for showing or hiding the title bar and toolbar of the NavDestination component takes effect only when the title bar or toolbar is visible.
- If a NavDestination component is bound to multiple scrollable containers, scrolling in any of these containers triggers the display or hiding animations of the title bar and toolbar. Specifically, when any scrollable container reaches either the bottom or the top, the display animation for the title bar and toolbar is triggered without delay. As such, to ensure the optimal user experience, avoid triggering scroll events of multiple scrollable containers simultaneously.

Example 4: Configuring Display Orientation and Status Bar and Navigation Bar Visibility
This example demonstrates how to configure each NavDestination component with specific display orientations and control the visibility of the status bar and navigation bar.
import { window } from '@kit.ArkUI';
@Component
struct PortraitPage {
private stack: NavPathStack|undefined = undefined;
build() {
NavDestination() {
Stack({alignContent: Alignment.Center}) {
Button('push LANDSCAPE page').onClick(() => {
this.stack?.pushPath({name: 'landscape'})
})
}.width('100%').height('100%')
}
.width('100%').height('100%')
.title('PortraitPage')
.preferredOrientation(window.Orientation.PORTRAIT) // Portrait orientation.
.enableStatusBar (true) // Show the status bar.
.enableNavigationIndicator(true) // Show the navigation bar.
.backgroundColor('#ffbaece9')
.onReady((ctx: NavDestinationContext) => {
this.stack = ctx.pathStack;
})
}
}
@Component
struct LandscapePage {
private stack: NavPathStack|undefined = undefined;
build() {
NavDestination() {
Stack({alignContent: Alignment.Center}) {
Button('push PORTRAIT page').onClick(() => {
this.stack?.pushPath({name: 'portrait'})
})
}.width('100%').height('100%')
}
.width('100%').height('100%')
.title('LandscapePage')
.preferredOrientation(window.Orientation.LANDSCAPE) // Landscape orientation.
.enableStatusBar(false) // Hide the status bar.
.enableNavigationIndicator(false) // Hide the navigation bar.
.backgroundColor('#ffecb8b8')
.ignoreLayoutSafeArea([LayoutSafeAreaType.SYSTEM], [LayoutSafeAreaEdge.TOP, LayoutSafeAreaEdge.BOTTOM])
.onReady((ctx: NavDestinationContext) => {
this.stack = ctx.pathStack;
})
}
}
@Entry
@Component
struct ExamplePage {
private stack: NavPathStack = new NavPathStack();
aboutToAppear(): void {
this.stack.pushPath({name: "portrait"})
}
@Builder
MyPageMap(name: string) {
if (name === 'portrait') {
PortraitPage()
} else {
LandscapePage()
}
}
build() {
Navigation(this.stack) {
}
.width('100%')
.height('100%')
.hideNavBar(true)
.navDestination(this.MyPageMap)
}
}
