Simple Stack Compose Integration
Default behavior for Jetpack Compose using Simple-Stack.
Using Simple Stack Compose Integration
In order to use Simple Stack Compose Integration, you need to add jitpack to your project root build.gradle.kts (or build.gradle):
// build.gradle.kts
allprojects {
repositories {
// ...
maven { setUrl("https://jitpack.io") }
}
// ...
}
or
// build.gradle
allprojects {
repositories {
// ...
maven { url "https://jitpack.io" }
}
// ...
}
and then, add the dependency to your module's build.gradle.kts (or build.gradle):
// build.gradle.kts
implementation("com.github.Zhuinden.simple-stack-compose-integration:0.2.0")
or
// build.gradle
implementation 'com.github.Zhuinden.simple-stack-compose-integration:0.2.0'
As Compose requires Java-8 bytecode, you need to also add this:
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
kotlinOptions {
jvmTarget = '1.8'
useIR = true
}
buildFeatures {
compose true
}
What does it do?
Provides defaults for Composable-driven navigation and animation support.
class MainActivity : AppCompatActivity() {
private val composeStateChanger = AnimatingComposeStateChanger() // <--
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
val backstack = Navigator.configure()
.setStateChanger(AsyncStateChanger(composeStateChanger)) // <--
.install(this, androidContentFrame, History.of(FirstKey()))
setContent {
BackstackProvider(backstack) { // <--
MaterialTheme {
Box(Modifier.fillMaxSize()) {
composeStateChanger.RenderScreen() // <--
}
}
}
}
}
override fun onBackPressed() {
if (!Navigator.onBackPressed(this)) {
super.onBackPressed()
}
}
}
and
abstract class ComposeKey: DefaultComposeKey(), Parcelable {
override val saveableStateProviderKey: Any = this // data class + parcelable!
}
and
@Immutable
@Parcelize
data class SecondKey(private val noArgsPlaceholder: String = ""): ComposeKey() {
@Composable
override fun ScreenComposable(modifier: Modifier) {
SecondScreen(modifier)
}
}
