当按下C键时，这个应用程序计算A。由于A是唯一改变的，我期望重组就是这样。但是C也是重组。

下面是代码。
ViewModel公开状态流。

class MainViewModel : ViewModel() {
  private val _count: MutableStateFlow<Int> = MutableStateFlow(0)
  val count: StateFlow<Int> = _count.asStateFlow()
  fun increaseCount() {
    _count.value++
  }
}

CCompose调用increaseCount()。

@Composable
fun CountUpScreen(
  modifier: Modifier = Modifier,
  viewModel: MainViewModel = viewModel(),
) {
  val count: Int by viewModel.count.collectAsState()
  SideEffect { println("CountUpScreen") }
  Column(
    modifier = modifier.fillMaxSize(),
    verticalArrangement = Arrangement.SpaceEvenly,
    horizontalAlignment = Alignment.CenterHorizontally,
  ) {

    ACompose(
      count = count
    )
    BCompose()
    CCompose {
      viewModel.increaseCount()
    }
  }
}

@Composable
private fun ACompose(count: Int) {
  SideEffect { println("ACompose") }
  Column(modifier = Modifier.fillMaxWidth(), horizontalAlignment = Alignment.CenterHorizontally) {
    Text(
      text = "$count"
    )
  }
}

@Composable
private fun BCompose() {
  SideEffect { println("BCompose") }
  Text(
    text = "I am composable that will not be recompose"
  )
}

@Composable
private fun CCompose(onClick: () -> Unit) {
  SideEffect { println("CCompose") }
  Button(onClick = {
    onClick()
  }) {
    Icon(Icons.Outlined.Add, contentDescription = "+")
  }
}

以下是进行累加的日志的结果。

I/System.out: ACompose
I/System.out: CCompose

CCompose为何要重新撰写？
