I’m creating an utility with Kotlin Multiplatform utilizing Compose Multiplatform, I’m utilizing the Voyager library to do the navigation of the appliance.
I’ve a BottomNavigationBar configured and it really works appropriately and inside the principle Tab I’ve a button that navigates to a Display screen, the issue is that after I navigate to the Display screen, it replaces the Tab and if I click on once more on the BottomNavigationBar to return to that important display, it does nothing.
@Composable
enjoyable App() {
val tabs = listOf(HomeTab, MapsTab)
MaterialTheme {
TabNavigator(tab = HomeTab,
tabDisposable = {
TabDisposable(
navigator = it,
tabs = tabs
)
}
) {
Scaffold(topBar = {
TopAppBar(title = {
Textual content(textual content = it.present.choices.title)
})
}, bottomBar = {
BottomNavigation {
tabs.forEach { tab ->
TabNavigationItem(tab)
}
}
}, content material = {
CurrentTab()
})
}
}
}
@Composable
enjoyable RowScope.TabNavigationItem(tab: Tab) {
val tabNavigator = LocalTabNavigator.present
BottomNavigationItem(
chosen = tabNavigator.present.key == tab.key,
onClick = {
tabNavigator.present = tab
},
icon = {
tab.choices.icon?.let { safePainter ->
Icon(
painter = safePainter,
contentDescription = tab.choices.title
)
}
}
)
}
object HomeTab : Tab {
override val choices: TabOptions
@Composable
get() {
val icon = rememberVectorPainter(Icons.Default.House)
return keep in mind {
TabOptions(
index = 0u,
title = "House",
icon = icon
)
}
}
@Composable
override enjoyable Content material() {
Navigator(display = HomeScreen()) { navigator ->
SlideTransition(navigator = navigator)
}
}
}
class HomeScreen : Display screen {
@Composable
override enjoyable Content material() {
val navigator = LocalNavigator.currentOrThrow
Column(
modifier = Modifier.fillMaxSize(),
horizontalAlignment = Alignment.CenterHorizontally,
verticalArrangement = Association.Heart
) {
Button(onClick = {
navigator.push(DetailScreen())
}) {
Textual content("Go to element")
}
}
}
}
I perceive why that is taking place, and that’s that when I’m in DetailScreen, the Tab continues to be the identical, so it tries to make CurrentTab() the identical because it already is, however I do not know find out how to change this behaviour.
