viewModel() 오류 추가질문입니다

lifecycle_version 이 2.5.1 이면 오류가 사라지나

2.6.2 로 하였을때는

import androidx.lifecycle.viewmodel.compose.viewModel

가 되지 않았습니다

그래서 build.gradle 파일내용을 아래와 같이 수정하여 실행하니 오류가 사라졌습니다

dependencies {
    val lifecycle_version = "2.5.1"
    val arch_version = "2.1.0"

    // ViewModel
    implementation("androidx.lifecycle:lifecycle-viewmodel-ktx:$lifecycle_version")
    // ViewModel utilities for Compose
    implementation("androidx.lifecycle:lifecycle-viewmodel-compose:$lifecycle_version")
    // LiveData
    implementation("androidx.lifecycle:lifecycle-livedata-ktx:$lifecycle_version")
    // Lifecycles only (without ViewModel or LiveData)
    implementation("androidx.lifecycle:lifecycle-runtime-ktx:$lifecycle_version")

    // Saved state module for ViewModel
    implementation("androidx.lifecycle:lifecycle-viewmodel-savedstate:$lifecycle_version")

    // alternately - if using Java8, use the following instead of lifecycle-compiler
    implementation("androidx.lifecycle:lifecycle-common-java8:$lifecycle_version")

    // optional - helpers for implementing LifecycleOwner in a Service
    implementation("androidx.lifecycle:lifecycle-service:$lifecycle_version")

    // optional - ProcessLifecycleOwner provides a lifecycle for the whole application process
    implementation("androidx.lifecycle:lifecycle-process:$lifecycle_version")

    // optional - ReactiveStreams support for LiveData
    implementation("androidx.lifecycle:lifecycle-reactivestreams-ktx:$lifecycle_version")

    // optional - Test helpers for LiveData
    testImplementation("androidx.arch.core:core-testing:$arch_version")

    // optional - Test helpers for Lifecycle runtime
    testImplementation ("androidx.lifecycle:lifecycle-runtime-testing:$lifecycle_version")

class MainActivity : ComponentActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContent {
            HomeScreen()
        }
    }
}

@Composable
fun HomeScreen(viewModel : MainViewModel = viewModel()) {
    Column() {
        Text("Hello World")
        Button(onClick = {  }) {
            Text("Click !")
        }
    }
}

class MainViewModel: ViewModel() {
    private val _value = mutableStateOf("Hello World")
    val value: State<String> = _value
