我尝试发布一个状态为"Loading"，以便在从服务器下载数据时向用户显示进度条，它看起来像这样：

private fun loadBottomSheetItems(currentViewState: BusinessMapViewState.Display, getBusinessByIdsRequest: GetBusinessByIdsRequest) {
 
    viewModelScope.launch {
        _businessMapViewState.postValue(
            currentViewState.copy(
                bottomSheetState = BottomSheetViewState.Loading <--------------- Always that state!
            )
        )
 
        val responseFlow = businessRepository.getBusinessListByIds(
            getBusinessByIdsRequest
        )
 
        responseFlow.collect { result ->
            if (result.isSuccess()) {
                val businesses = result.asSuccess().value.businessList
 
                _businessMapViewState.postValue(
                    currentViewState.copy(
                        bottomSheetState = BottomSheetViewState.Display(
                            items = businesses.map { business ->
                                BusinessListCardItemModel(
                                    businessId = business.id,
                                    businessName = business.name
                                )
                            }
                        )
                    )
                )
            } else {
                _businessMapViewState.postValue(
                    currentViewState.copy(
                        bottomSheetState = BottomSheetViewState.Error
                    )
                )
            }
        }
    }
}

但是，当我发布"Loading"状态时，该状态在数据加载后不会更改。
如果我删除"Loading"状态的postValue块，或者添加延迟，数据会正确显示，但是我需要一个进度条。
我还尝试将"Loading"状态的postValue块移出viewModelScope，但没有任何变化

我解决了这个问题，代码的另一部分是更改ui的状态🙈
