问题 For example, I am trying to obtain data emitted for multiple streams at once, but 2 or more of these streams emit data of the same type, lets say a string. My question is, is it possible to use MultiProvider and use multiple StreamProvider (or any provider, but I am interested in this case) of the same type while still being able to access the data emitted by each one of them? A solution for this is using a StreamBuilder when using common data types but I really like what the MultiProvider

问题 How do I decouple a class from its attributes when methods of the attributes need to modify the state of the owning class? Alternatively, how can I redesign the architecture so that this isn't a problem? This question is a bit abstract, but I keep coming across this problem time and time again. I spend a lot of time designing my code base so that my classes are "high cohesion and low coupling", but then as the code evolves over time, they end up becoming more closely coupled. I'll give the

问题 I'm trying to use both SuperGraph as-a-library and GqlGen. So I have two handlers: the first one is SuperGraph ; this checks that it can carry out the operation the second one is GqlGen ; this checks that it can carry out the operation if the first one can't The code I'm using is this: type reqBody struct { Query string `json:"query"` } func Handler(sg *core.SuperGraph, next http.Handler) http.HandlerFunc { return func(w http.ResponseWriter, r *http.Request) { bodyBytes, _ := ioutil.ReadAll(r

问题 For example, I have this Kotlin class and method (Spring-managed class if it matters): import org.springframework.stereotype.Service import java.time.LocalDateTime data class TestObj( val msg: String, val dateTime: LocalDateTime ) @Service class TestAnotherService { fun doSmthng1(testObj: TestObj) { println("Oh my brand new object : $testObj") } } @Service class TestService( private val testAnotherService: TestAnotherService ) { fun doSmthng() { testAnotherService.doSmthng1(TestObj("my

问题 I am currently working on an online card game, similar to blackjack, which will consist of a series of tables where each table has a "dealer" and multiple human players. The dealer (a computer bot) is responsible for dealing and shuffling cards. The tables will be stored in a PostgreSQL database table and it will be possible for a human admin to add/remove/edit tables. The game will consist of a web front end and a REST/websocket API backend. I will probably use Kubernetes and Nginx as a load

问题 I am designing a booking system which allows users to view available time slots on a mobile app and book one of them. Each time slot consists of 15-minute. If we calculate total time slots available in a day (10:00am - 00:00am), they'll be 56. We will have multiple servicemen, for example 3-5, can be more. This means we will have 56 x 5 = 280 time slots each day and if we offer booking for next 7 days they'll become 280 x 7 = 1960 time slots. I am intending to use MySQL as the database,
