问题 I've one LiveData named sortOrder and then I've another variable named myData that observes any change to sortOrder and populates data accordingly. class TestViewModel @ViewModelInject constructor() : ViewModel() { private val sortOrder = MutableLiveData<String>() val myData = sortOrder.map { Timber.d("Sort order changed to $it") "Sort order is $it" } init { sortOrder.value = "year" } } Observing in Activity class TestActivity : AppCompatActivity() { private val viewModel: TestViewModel by

问题 I have an android app in which I'm trying to use coroutine flows to replace the existing Otto EventBus using my own event bus library. I'm seeing dropped values when setting the MutableStateFlow's value and then collecting in my app's code. I've created a much simpler project that demonstrates the same issue. Any thoughts on why values are being dropped from the MutableStateFlow? Project's build.gradle buildscript { ext.kotlin_version = "1.4.10" repositories { google() jcenter() }
