cl.arkui.1 Resource Type Support Added for Navigation and NavDestination Components’ title and menus APIs
Access Level
Public API
Reason for Change
This change is made for enhancement of basic capabilities.
Change Impact
This change is a non-compatible change.
After the type of NavigationMenuItem changes to string|Resource, it no longer matches a single variable type of string. Therefore, assigning NavigationMenuItem to a string type variable will result in a compilation error.
@State myString: string = '';
@State myIcon: NavigationMenuItem["value"] = $r("app.string.MyTestMenuValue1")
this.myString = this.myIcon
