I can't get the new

ModalBottomSheet

component to show up in a

@Preview

nor in screenshot tests (w/showkase+paparazzi). Both the preview and screenshots are completely empty, not even the scrim is shown. Though if I click on "Start interactive mode" the animation starts, the scrim appears and the bottom sheet too. I'm using this

sheetState

for the `@Preview`:

SheetState(
                skipPartiallyExpanded = true,
                initialValue = SheetValue.Expanded,
                skipHiddenState = true,
            )

Any ideas?

What's the best (most stable, feature complete) mqtt client library to use in Kotlin?

Does Kotlin have a Ring-Array? (Or Dequeue or ringbuffer or however one calls it)

Im working with Compose Multiplatform project for Android and Desktop. I added Room following the doc, but Im getting the this error:

Execution failed for task ':composeApp:mergeDebugAndroidTestAssets'.
> The value for task ':composeApp:copyRoomSchemasToAndroidTestAssetsDebugAndroidTest' property 'inputDirectory' is final and cannot be changed any further.

Is there a known issue with Gradle 8.4 that leads to IDEA failing to load (Kotlin) build script configurations? The IDEA logs aren't helpful and I'm struggling to find anything relevant on YouTrack or the Gradle issue tracker right now.

Hi guys, I’ve KMM project that uses Firebase database [https://github.com/GitLiveApp/firebase-kotlin-sdk] and i’m getting an exception when offline caching is enabled. This issue only happens on the first app install, and doesn’t not occur after that:

E  com.google.firebase.database.DatabaseException: Failed to gain exclusive lock to Firebase Database's offline persistence. This generally means you are using Firebase Database from multiple processes in your app. Keep in mind that multi-process Android apps execute the code in your Application class in all processes, so you may need to avoid initializing FirebaseDatabase in your Application class. If you are intentionally using Firebase Database from multiple processes, you can only enable offline persistence (i.e. call setPersistenceEnabled(true)) in one of them.

Giving it a try now... but I'm getting an error in Android Studio that flow operators shouldn't be used in composables... will I have to do

@SuppressLint("FlowOperatorInvokedInComposition")

for each of them? It seems to me that in the context of Molecule presenters there's no real problem in transforming/filtering flows... maybe there's a way for the library to suppress those warnings for it's functions somehow?

Is there an easy way to call suspend functions from Java 7? I saw some useful APIs in kotlinx-coroutines-jdk8 but that's bit too high for Android

How do I wait for a coroutine scope to actually finish after calling

cancel()

. I'm trying to write client-server unit tests and I would like to properly clean up at the end of each case. However, if I do not add a

delay(1000)

after

cancel()

, I get an exception like

java.util.concurrent.RejectedExecutionException: event executor terminated

(1000 in the delay is not really important 100 works just as well).

How can I get around

Overload resolution ambiguity

for a function that has two

varargs

single-argument signatures?

Overload resolution ambiguity. All these functions match.
public open fun <T : Any!> array(vararg values: TypeVariable(T)!): Field<Array<(out) TypeVariable(T)!>!> defined in org.jooq.impl.DSL
public open fun <T : Any!> array(vararg fields: Field<TypeVariable(T)!>!): Field<Array<(out) TypeVariable(T)!>!> defined in org.jooq.impl.DSL

It works in Java, but not in Kotlin. I can't use

null

or `emptyArray()`/`emptyList()` because that produces the wrong results =/
