Does it correct create viewModelscope.launch on every request? Kotlin Flow, coroutines-CodePudding

i have code like this:

class MyViewModel: ViewModel() {

    val myRepository = ExampleRepository()

init {
    fetchServerRequest()
}

fun reload() {
    fetchServerRequest()
}

private fun fetchServerRequest(){
    viewModelScope.launch {
        myRepository.fetchServerRequest() //repository returns Flow<String>
            .collect {
                //handle result
            }
    }
}

And my question is: Repository returns cold Flow. Does it correct to create new coroutine c every time when i call this method?

Or coroutine will be finished when code in collect will finished?

CodePudding user response：

What you are doing is fine, viewModelScope.launch() isn't creating a new Coroutine, it creates a new Job, you can see the return type if you put the mouse on the launch().

Or coroutine will be finished when code in collect will finished?
