Sequential network request

• This use case performs two network requests sequentially.
• First it retrieves recent Android Versions and then it requests the features of the latest version.

class Perform2SequentialNetworkRequestsViewModel(
    private val mockApi: MockApi = mockApi()
) : BaseViewModel<UiState>() {

    fun perform2SequentialNetworkRequest() {
        uiState.value = UiState.Loading
        viewModelScope.launch {
            try {
                val recentVersions = mockApi.getRecentAndroidVersions()
                val mostRecentVersion = recentVersions.last()

                val featuresOfMostRecentVersion =
                    mockApi.getAndroidVersionFeatures(mostRecentVersion.apiLevel)

                uiState.value = UiState.Success(featuresOfMostRecentVersion)
            } catch (exception: Exception) {
                uiState.value = UiState.Error("Network Request failed")
            }
        }
    }
}
