Maps each emitted KQLiteCursor from the upstream Flow into a List.

mapToSingle

fun <T> KQLiteCursor.mapToSingle(mapper: (KQLiteCursor) -> T): T

Maps the first row of this KQLiteCursor into a single object of type T using mapper.

fun <T> Flow<KQLiteCursor>.mapToSingle(dispatcher: CoroutineDispatcher? = null, mapper: (KQLiteCursor) -> T): Flow<T>

Maps each emitted KQLiteCursor from the upstream Flow into a single object of type T.
