Karavel is a very simple and lightweight navigation library for Compose for Desktop. It creates a stack of composables and let you navigate poping and pushing on this stack.
Karavel was discontinued. We recomment alternative libraries to setup your navigation in a Jetpack compose app. Our recommentation is to use Voyager.
Add the dependency on you build.gradle.kts file
dependencies {
// ...
implementation("io.github.app-outlet:karavel:<version>")
}import androidx.compose.runtime.Composable
import io.appoutlet.karavel.Page
// 1. Extends the Page class
class MainPage : Page() {
// 2. Override the content() method and annotate it with composable
@Composable
override fun content() {
// ...Page content...
}
}fun main() = application {
Window(onCloseRequest = ::exitApplication) {
// 3. Create karavel instance passing the main page as argument
val karavel = Karavel(MainPage())
MaterialTheme {
// 4. Get the current page content
karavel.currentPage().content()
}
}
} @Composable
override fun content() {
Button(onClick = {
// 5. use the karavel object to navigate
karavel?.navigate(SettingsPage())
}) {
Text("Go to settings page")
}
Button(onClick = {
// 6. use the karavel object to back to the previous screen
karavel?.back()
}) {
Text("Back to previous screen")
}
