Can someone tell me why otp value not updated by resetText?
Steps:

1. type some text in TextField
2. click “Reset text”

Is it bug or some issues with my code?

ViewModel

@HiltViewModel
class MyViewModel @Inject constructor() : ViewModel() {
    val state = MutableStateFlow(SomeState())

    fun resetText() {
        state.update { it.copy(text = null) }
    }

    fun changeText() {
        state.update { it.copy(text = Math.random().toString()) }
    }
}

State class

data class SomeState(
    val text: String? = null
)

View

@Composable
fun SomeView(modifier: Modifier = Modifier) {
    val viewModel = hiltViewModel<MyViewModel>()
    val state by viewModel.state.collectAsState()
    var otp by rememberSaveable(state.text) { mutableStateOf(state.text) }
    Column(
        modifier = modifier
            .padding(horizontal = 16.dp)
            .background(Color.White)
            .fillMaxSize(),
        verticalArrangement = Arrangement.SpaceEvenly,
        horizontalAlignment = Alignment.CenterHorizontally
    ) {
        TextField(
            value = otp.orEmpty(),
            onValueChange = { otp = it }
        )
        Button(onClick = { viewModel.resetText() }) {
            Text(text = "reset text")
        }
        Button(onClick = { viewModel.changeText() }) {
            Text(text = "Change text")
        }
    }
}

P.S. I made it work by changing resetText to

fun resetText() {
        viewModelScope.launch {
            state.update { it.copy(text = "") }
            delay(100)
            state.update { it.copy(text = null) }
        }
    }

but it’s obviously bad option
