@jw what about when we request as flow ?

will

fun getActiveCurrencies() = currencyQueries
        .getActiveCurrencies()
        .asFlow()
        .flowOn(ioDispatcher)
        .mapToList(ioDispatcher)

be enough ? or should we still call with withContext like this?

suspend fun getActiveCurrencies() = withContext(ioDispatcher) {
        currencyQueries
            .getActiveCurrencies()
            .asFlow()
            .flowOn(ioDispatcher)
            .mapToList(ioDispatcher)
    }

Remove flowOn

[jw]

Also withContext

[jw]

Also suspend

Thanks a lot for the answers! Removing withContext and suspend makes perfect sense, but I confused about removing the flowOn(ioDispatcher) is SQLDelight emitting value changes on IO thread ?

You pass a dispatcher to the map function which is where the query is executed

[Mustafa Ozhan]

Ohh right, the rest actually doesn’t require the context in terms of the querying 👍 Thanks a lot!
