How to use AndroidX ViewModels in Compose Desktop application? #4978

Closed Mikkareem closed 1 week ago

Mikkareem commented 1 week ago 
class FooViewModel: ViewModel() {
       private fun fetchSomething() {
               viewModelScope.launch {
                      Repository.fetch()
               }
       }

       init { fetchSomething() }
}

@Composable
fun FooScreen() {
       val viewModel = viewModel<FooViewModel>()

      // Rest of the code
}

The dependencies I include, 

import org.jetbrains.compose.desktop.application.dsl.TargetFormat

plugins {
    kotlin("jvm")
    id("org.jetbrains.compose")
    id("org.jetbrains.kotlin.plugin.compose")
    kotlin("plugin.serialization")
}

group = "com.examples"
version = "1.0-SNAPSHOT"

repositories {
    mavenCentral()
    maven("https://maven.pkg.jetbrains.space/public/p/compose/dev")
    google()
}

dependencies {
    // Note, if you develop a library, you should use compose.desktop.common.
    // compose.desktop.currentOs should be used in launcher-sourceSet
    // (in a separate module for demo project and in testMain).
    // With compose.desktop.common you will also lose @Preview functionality
    implementation(compose.desktop.currentOs)
    implementation(compose.material3)

    val ktor = "2.3.11"
    implementation("io.ktor:ktor-client-core:$ktor")
    implementation("io.ktor:ktor-client-okhttp:$ktor")
    implementation("io.ktor:ktor-client-content-negotiation:$ktor")
    implementation("io.ktor:ktor-serialization-kotlinx-json:$ktor")

    implementation("org.jetbrains.androidx.lifecycle:lifecycle-viewmodel-compose:2.8.0")
}

compose.desktop {
    application {
        mainClass = "MainKt"

        nativeDistributions {
            targetFormats(TargetFormat.Dmg, TargetFormat.Msi, TargetFormat.Deb)
            packageName = "TempApp"
            packageVersion = "1.0.0"
        }
    }
}

The Runtime Exception which I get is,

i think you need -> implementation("org.jetbrains.kotlinx:kotlinx-coroutines-swing:1.8.1") (check if this version is the latest)

MatkovIvan commented 1 week ago

You can find documentation here: https://www.jetbrains.com/help/kotlin-multiplatform-dev/compose-viewmodel.html

When running coroutines in a ViewModel, remember that the ViewModel.viewModelScope value is tied to the Dispatchers.Main.immediate value, which might be unavailable on desktop by default. To make ViewModel coroutines work correctly with Compose Multiplatform, add the kotlinx-coroutines-swing dependency to your project. See the Dispatchers.Main documentation for details.
