I’m using a MutableMap to save the data which is updates every 5 seconds and I expect also to be updated the UI showing part of the Map.
After trying different solution I found that if I add another Double variable both Map and **Double **are updated on the UI but if I keep only Map variable nothing changes:

ViewModel Variables:

    private val _stockRealPriceFlow = MutableStateFlow<MutableMap<String, Double>>(mutableMapOf())
    val stockRealPriceFlow: StateFlow<MutableMap<String, Double>> = _stockRealPriceFlow.asStateFlow()

**    private val _draftPrice = MutableLiveData<Double>()
    val draftPrice: LiveData<Double> = _draftPrice **

ViewModel Variables Update:

        _stockRealPriceFlow.value[it.name] = it.currentPrice()
**      _draftPrice.value = stockRealPriceFlow["Draft"] ?: 0.0
**

Activity:

    val stockRealPriceFlow by viewModel.stockRealPriceFlow.collectAsState()
**    val draftPrice by viewModel.draftPrice .observeAsState(0.0)
**
    Column(
        modifier = Modifier
            .padding(8.dp)
    ) {
        Text(text = stockRealPriceFlow["Draft"].toString())
**        Text(text = draftPrice.toString())
**    }

How that can be explained if the MutableMap variable is same in both cases?
What is the correct way of working with the map on this case?

I expect UI always show the Map values.
