kotlin - Alertdialog 中的 LazyColumn 在 Jetpack Compose 中显示错误

Question

我正在尝试在警告对话框中显示一个 LazyColumn，以便用户可以在项目列表之间进行选择，然后单击它。警报对话框将毫无问题地显示，我可以单击屏幕上的任何项目并将其关闭，但是一旦我尝试在这些项目之间滚动，它就会出现以下错误:

E/InputEventReceiver: Exception dispatching input event.
D/AndroidRuntime: Shutting down VM
E/AndroidRuntime: FATAL EXCEPTION: main
    Process: com.example.app, PID: 22418

这是AlertDialog代码:

AlertDialog(
    onDismissRequest = { showDialog.value = false },
    modifier = Modifier.fillMaxHeight(.80f),
    text = {
        LazyColumn{
            items(30){ i ->
                Text(text = i.toString())
            }
        }
    },
    buttons = {
            Button(onClick = { /*TODO*/ }) {
                Text(text = "Cancel")
            }
    }
)

同样的问题发生在我身上，虽然我发现如果我使用 Material3 库滚动不再是问题:

implementation "androidx.compose.material3:material3:1.0.0-alpha03"

AlertDialog(
        onDismissRequest = { },
        modifier = Modifier.fillMaxHeight(0.8f),
        text = {
            LazyColumn() {
                items(30) { i ->
                    Text(text = i.toString())
                }
            }
        },
        dismissButton = {
            Button(onClick = { /*TODO*/ }) {
                Text(text = "Cancel")
            }
        }
    )

确保导入:

import androidx.compose.material3.AlertDialog

我不知道这是否是正确的答案，但我希望它在任何情况下都有帮助。
