Android 懒惰列的滚动到项目不按预期工作'

当键盘出现时，我正试图自动将LazyColumn滚动到最后一个项目.然而，下面的代码是在其他StackOverflow讨论中建议的，其工作方式不一致，如所附图片所示，并且很少将最后一个项目带到视图中.

@OptIn(ExperimentalLayoutApi::class)
@Preview(showBackground = true)
@Composable
fun ChatScreen() {

    val viewModel: ChatScreenViewModel = viewModel()
    val textFieldContent = viewModel.textFieldState
    val messages =  viewModel.messageListState
    val listState = viewModel.messageListScrollState
    val keyboardVisibility = WindowInsets.isImeVisible

    LaunchedEffect(key1 = keyboardVisibility) {

        listState.animateScrollToItem(listState.layoutInfo.totalItemsCount)
    }

    ChatbotAppTheme {

        Column(
            modifier = Modifier
                .fillMaxSize()
                .systemBarsPadding()
                .imePadding()
        ) {
            // LazyColumn to hold messages
            LazyColumn(
                modifier = Modifier
                    .weight(1f),
                state = listState

            ) {
                items(messages) {
                    MessageBubble(
                        text = it.body,
                        role = it.role
                    )
                }
            }

            Row(
                modifier = Modifier
                    .fillMaxWidth()
                    .background(Color.Transparent),
                verticalAlignment = Alignment.CenterVertically,
                horizontalArrangement = Arrangement.SpaceAround
            ) {
                CustomTextField(
                    modifier = Modifier.weight(1f),
                    text = textFieldContent.value,
                    onValueChangeFunc = {viewModel.onTextFieldContentChanged(it)},
                    trailingIconFunc = {viewModel.clearTextField()},
                )
                CustomButton (enabled = textFieldContent.value.isNotEmpty()) {
                    viewModel.onSendButtonPressed()

                }
            }
        }
    }
}

我已经在 list 中设置了所需的android:windowSoftInputMode="adjustResize"，并在MainActivity中设置了enableEdgeToEdge()，以确保isImeVisible正常工作.但是，我无法得到预期的结果.我真的很感激任何帮助或洞察力.
