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") }
    }
    // ...
}
// 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")
// 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()
        }
    }
}
abstract class ComposeKey: DefaultComposeKey(), Parcelable {
    override val saveableStateProviderKey: Any = this // data class + parcelable!
}
@Immutable
@Parcelize
data class SecondKey(private val noArgsPlaceholder: String = ""): ComposeKey() {
    @Composable
    override fun ScreenComposable(modifier: Modifier) {
        SecondScreen(modifier)
    }
}
