kotlin.NotImplementedError: An operation is not implemented: not implemented AlertDialog

Question

I was trying to practice a little with desktop compose for kotlin and when i was trying to implement AlertDialog element I got this exception:

Exception in thread "AWT-EventQueue-0 @coroutine#3" kotlin.NotImplementedError: An operation is not implemented: not implemented

The code that im trying to run :

fun main() {
    var text = mutableStateOf(0F)
    var num = mutableStateOf("a")
    Window(
        size = IntSize(500, 500),
        title = num.value,
        menuBar = MenuBar(
            Menu(
                name = "Test",
                MenuItem(
                    name = "Dodaj random",
                    onClick = {
                        text.value = text.value + Random.nextFloat()
                        if (text.value > 1F) {
                            text.value = 0F
                            num.value += "a"
                        }
                    },
                    shortcut = KeyStroke(Key.A)
                ),
                MenuItem(
                    name = "Exit",
                    onClick = {
                        AppManager.exit()
                    },
                    shortcut = KeyStroke(Key.L)
                )
            )
        )
    ) {

        MaterialTheme {
            Column(Modifier.fillMaxSize(), Arrangement.spacedBy(12.dp)) {
                LinearProgressIndicator(text.value.toFloat(), modifier = Modifier.align(Alignment.CenterHorizontally))
                val openDialog = remember { mutableStateOf(false) }
                Button(
                    onClick = {
                        openDialog.value = true
                    }) {
                    Text("Click me!")
                }
                if (openDialog.value) {
                    AlertDialog(
                        onDismissRequest = { openDialog.value = false },
                        title = { Text("Dialog title") },
                        text = { Text("Here is a text") },
                        confirmButton = {
                            Button(
                                onClick = {
                                    openDialog.value = false
                                }
                            ) { Text("Confirm butt") }
                        },
                        dismissButton = {
                            Button(
                                onClick = {
                                    openDialog.value = false
                                }
                            ) { Text("Diss butt") }
                        }
                    )
                }
                Button(
                    onClick = {
                        text.value += 0.1F
                        if (text.value > 1F) {
                            text.value = 0F
                            num.value += "a"
                        }
                    },
                    modifier = Modifier.align(Alignment.CenterHorizontally)
                ) {
                    Text(text.value.toString())
                }

                Button(
                    onClick = {
                        num.value += "a"
                    },
                    modifier = Modifier.align(Alignment.CenterHorizontally)
                ) {
                    Text(num.component1())
                }


            }
        }
    }
}

Only when I'm trying to click on the "Click me" button I'm getting this exception other buttons works perfectly.

Your issue seems related to this github issue.

To solve it simply update compose dependency to 0.2.0-build132.

Complete example of my build.gradle with the correct versions:

import org.jetbrains.compose.compose

plugins {
    kotlin("jvm") version "1.4.20"
    id("org.jetbrains.compose") version "0.2.0-build132"
}

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

dependencies {
    implementation(compose.desktop.currentOs)
}

compose.desktop {
    application {
        mainClass = "MainKt"
    }
}
