I wish the trailing-comma rule defaulted to adding a redundant trailing comma. It makes it easier to add items later on, and such changes only shows a diff on the actual changed line. Basically just benefits of having the comma there. 🙂

Hi, I created a simple web app with Kotlin/Wasm using Compose multiplatform. The issue I’m experiencing comes when running the website on mobile device browsers. AFAIK Kotlin/Wasm doesn’t work on Safari browsers. However, some Android devices can run the web and some other Android devices experience a blank screen. On my iOS device I get a blank screen on both Safari (as expected) and Google Chrome. Is this normal? Do I have to add some configuration so that small screens can run my webapp?

Which is the best architecture to work with compose-desktop? maybe MVC or MVP are better than MVVM this time?

EDIT: I solved this I’m writing a test for a class handling a 3rd party analytics library. The class under test needs to handler an

Analytics

object, but unfortunately

mockk<Analytics>()

cannot create a mock because of a static android Handler in that class:

public class Analytics { // this is 3rd party code I can't change

  static final Handler HANDLER =
      new Handler(Looper.getMainLooper()) {
        @Override
        public void handleMessage(Message msg) {
          throw new AssertionError("Unknown handler message received: " + msg.what);
        }
      };
// rest of class here
}

I tried using both

mockk<Analytics>()

and adding

mockkConstructor(Handler::class)

but that didn’t work. Any suggestions?

What are the differences between HttpClient(CIO) and HttpClient(OkHttp) with regards to ktor-client not server? Thanks

I keep having

Module with the Main dispatcher is missing. Add dependency providing the Main dispatcher, e.g. 'kotlinx-coroutines-android' and ensure it has the same version as 'kotlinx-coroutines-core'

on a

jvm

target

did anyone successfully update project to use kotlin 2.1.20? I keep getting error:

After upgrading our project to K2 (Gradle 8.8) we've noticed that some

.salive

files are being created under

.kotlin/sessions

for some developers. Even after removal, after a few builds they keep coming back. Curiously, all files created are empty. I couldn't find more info on these files, are they important or just act like a log of some sorts? Is there a way to stop Kotlin from creating them?

I’m having an issue with Compose

@Preview

rendering. This shows up as “Render problem” in the preview pane:

java.lang.NullPointerException: Parameter specified as non-null is null

The parameter referenced in the message is just a

text: String

which gets passed to a text composable

Text(text = text)
