I'm planning to call method in suspend function that will throw IOException. In this case, IDE warn it as

Inappropriate blocking method call

. So, Should not I call method(will throw IOE) in suspend function?

suspend fun foo() {
    // warning: Inappropriate blocking method call
    throwIoException()

    withContext(<http://Dispatchers.IO|Dispatchers.IO>) {
        // warning: Inappropriate blocking method call
        throwIoException()
    }
}

@Throws(IOException::class)
fun throwIoException() {
    // something blocking process
}

doing it in IO dispatcher is fine

really IntelliJ shouldn't be warning there (second time, first time is valid) , and just like in the other thread it works for me without a warning, but apparently some how this is different for you

I see. But, IDE still warn when wrap as

withContext(<http://Dispatchers.IO|Dispatchers.IO>)

. So you mean that IDE is wrong?

Is it (still warn in withContext) occurring just my environment only..?

probably, I don't have my ide on hand right now but I have only seen the issue with flowOn, never withContext
