Why update() method from MutableStateFlow doesn't seem to work?
I'm actually creating a MutableStateFlow from a data class in this way
private val _uiState = MutableStateFlow(DataUiState())
val uiState: StateFlow = _uiState.asStateFlow()

When calling in this from:
val newsItems = repository.dataItems(item)
_uiState.update {
it.copy(dataItems = dataItems)
}

the method update {} shows a non-exist method error in compiler, why is this happening?
