I'm having an issue with LiveData's

observeAsState()

and Flow's

collectAsState()

just not being invoked on change anymore, where

observe()

and

collect()

lambdas are still being invoked on change. ViewModel:

private val _spellLiveData: MutableLiveData<DataState<List<Spell>>> = 
                MutableLiveData(DataState.Loading)
val spellLiveData: LiveData<DataState<List<Spell>>> = _spellLiveData
...
// Posting initial Loading, Success states
viewModelScope.launch {
   ...
    _spellLiveData.postValue(it)
}
...
// Posting new Success states with modified data
viewModelScope.launch {
   ...
    _spellLiveData.postValue(it)
}

MainActivity:

// This onChanged listener will always be invoked after a change.
viewModel.spellLiveData.observe(owner = this, onChanged = {
    Log.d(TAG, "onCreate: $it")
})

// This will stop being invoked after the initial Loading, then Success states.
// So we can't update it.
val spells by viewModel.spellLiveData.observeAsState(initial = DataState.Loading)

I'm fetching 308 DnD 5e Spells, each with a few paragraphs about how they're used, as well as some smaller fields. After posting the initial 308, I can't post another 308 in its place and have it update. But, when I post modified data with just 3 spells,

observeAsState()

and

collectAsState()

work fine, and the views recompose correctly. So I'm wondering if I've reached the limits of what state can do? I thought it might be a bug in

observeAsState()

, but the same problem occurs with Flow's

collectAsState()

.

Summary: Unable to inject Koin Workmanager I am getting

org.koin.core.error.NoBeanDefFoundException: No definition found for type 'androidx.work.WorkManager'. Check your Modules configuration and add missing type and/or qualifier!

When I try to inject WorkManager from Koin. I have in onCreate of Application

startKoin {
   androidContext(context)
   workManagerFactory() 
   modules(...

And Android Manifest

<provider
    android:name="androidx.startup.InitializationProvider"
    android:authorities="${applicationId}.androidx-startup"
    android:exported="false"
    tools:node="merge">
    <meta-data
        android:name="androidx.work.WorkManagerInitializer"
        android:value="androidx.startup"
        tools:node="remove" />
</provider>

And then injecting into my classes. Is there anything else I need to do to get WorkManager from Koin besides this?

I am trying to reconfigure out ktlint settings for a project. For the

ktlint_standard_trailing-comma-on-declaration-site

setting, the documentation is… highly confusing. https://pinterest.github.io/ktlint/latest/rules/standard/#trailing-comma-on-declaration-site It’s not clear if enabled or disabled will say yes to trailing commas. But I tried both (in

.editorconfig

), and in both cases, ktlint is removing trailing commas from my code base. I want it to either leave them alone or enforce having them, but neither enabled nor disabled is having that effect. What am I missing here?

How can I pass a String parameter to a ViewModel in Compose? In the codelabs they explain how to pass parameters than can be generated using Application, like this:

companion object {
        val factory : ViewModelProvider.Factory = viewModelFactory {
            initializer {
                MyViewModel(
                    MyApplication().container.repository
                )
            }
        }
    }

And later using that companion object variable like this:

viewModel: MyViewModel = viewModel(factory = MyViewModel.factory)

But they don't explain how to pass a simple String parameter 😕 How can I adapt that code for receiving a String as a parameter and passing it when initializing the viewModel?

After upgrading to Kotlin 2, no performance improvement in build time, it actually builds slower. Anyone saw improvements? Before Kotlin 2: https://github.com/wizbii/CinematicJourney/actions/runs/9269334388 After Kotlin 2: https://github.com/wizbii/CinematicJourney/actions/runs/9272294992 On the other hand, the upgrade was a bliss. Apart from the change of Compose plugin, nothing had to change, no migration needed, no problem with existing dependencies built against 1.9. Very nice!

I’m using a KMM library that declares a pod in it’s build.gradle.kts for iOS, and I’m having trouble running tests on the module that uses the library. If I don’t include

pod("FirebaseAnalytics")

in my build.gradle.kts, I get a missing symbol error when trying to run tests. If I add

pod("FirebaseAnalytics")

, I get

Compilation failed: Linking globals named 'knifunptr_cocoapods_FirebaseAnalytics0_kFIREventAdImpression_getter': symbol multiply defined!

. Is there a way to tell the cocoapods plugin that I want to pull down the binary, but I don’t care to have the cinterop generated in my module?

Now you can create your Compose Wasm web app from terminal 🎉 https://twitter.com/theapache64/status/1563862677063348224

Hello, I have a problem with JVM Multiplatform and Application plugins, I can not run my main

plugins {
    kotlin("multiplatform")
    application
}

application {
    mainClass.set("io.github.jervnorsk.aden.server.Main")
}

kotlin {
    jvm {
        testRuns["test"].executionTask.configure {
            useJUnitPlatform()
            testLogging {
                events = setOf(
                    org.gradle.api.tasks.testing.logging.TestLogEvent.FAILED,
                    org.gradle.api.tasks.testing.logging.TestLogEvent.PASSED
                )
                exceptionFormat = org.gradle.api.tasks.testing.logging.TestExceptionFormat.FULL

                showExceptions = true
                showStandardStreams = true
            }
        }

    }
    sourceSets {
        val commonMain by getting {
            dependencies {}
        }
        val commonTest by getting {
            dependencies {
                implementation(kotlin("test"))
            }
        }
        val jvmMain by getting {
            dependencies {
                implementation("io.ktor:ktor-server-core:${extra["ktor.version"]}")
                implementation("io.ktor:ktor-server-netty:${extra["ktor.version"]}")
                implementation("ch.qos.logback:logback-classic:1.2.5")
            }
        }
    }
}

So I did this and I hate it. How do you properly return results from one nav destination to another when popping back?

/**
 * Observes the callback result from previous NavController backStackEntry and makes sure,
 * that it's cleared so the LiveData doesn't trigger again (by default it triggers with the old value
 * for every resubscription)
 *
 * Ref: <https://developer.android.com/guide/navigation/navigation-programmatic#returning_a_result>
 */
fun <T> NavController.navigationCallbackFlow(argKey: String) = this
    .currentBackStackEntry!!
    .savedStateHandle
    .getLiveData<T>(argKey)
    .asFlow()
    .map { this.currentBackStackEntry!!.savedStateHandle.get<T>(argKey) }
    .onEach { this.currentBackStackEntry!!.savedStateHandle.remove<T>(argKey) }
    .filterNotNull()

How To achieve HorizontalPager Velocity Based Scrolling in accompanist pager? Context: I am using HorizontalPager and by default, it scrolls by 1 offset on a swipe. I want to implement a custom scroll, like if users swipes with a much larger velocity, then scroll accordingly like 5-6 cards ahead ... I saw FlingBehaviour is a parameter , but I wasn't able to understand on How to use it , any help will be appreciated and it would be gr8 if there is a sample / example showing such customization Is Fling Behaviour best suited ? OR can I disable Gestures/dragEnabled and Manually calculate scrollOffset using Modifier and then use animateScrollToPage (if this is the case , how to do this?) https://github.com/google/accompanist/discussions/529
