“ BehaviorSubject”和“ Sink”之间是否有任何关系？和`StreamController`？ [英] Are there any relationships btw `BehaviorSubject` and `Sink`? and `StreamController`?

问题描述

通过阅读@abin在 Flutter中的接收器和流之间的区别是什么？，我已经了解了btw 接收器和流。除此之外， BehaviorSubject ， BehaviorSubject.add ， StreamController 有什么关系？ code>， BehaviorSubject.stream 还是可能与 Sink ？我不知道 BehaviorSubject 和 Sink 是否存在任何关系。也许这两者根本没有关系？在Google I / O 2018视频中，它基本上只使用 BehaviorSubject.add 和 BehaviorSubject.stream 作为输出。谢谢。

By reading @abin's answer in What is the difference between Sink and Stream in Flutter?, I have understood the relation btw Sink and Stream. Other than that, What are the relationships btw BehaviorSubject, BehaviorSubject.add, StreamController, BehaviorSubject.stream or maybe with Sink? I have no idea if there are any relationships btw BehaviorSubject and Sink. Maybe these two have no relationship at all? In the Google I/O 2018 video, it basically just uses BehaviorSubject.add and BehaviorSubject.stream for the output. Thanks.

推荐答案

StreamController 具有 Stream 和接收器

BehaviorSubject 是 StreamController 的一种，可以记住添加到其接收器中的最后一个值

BehaviorSubject is a type of StreamController that can remember the last value added to its sink

BehaviorSubject 是RxDart的类，它是为Dart语言实现的反应式库的成员。

BehaviorSubject is a class from RxDart a member of reactive libraries implemented for Dart language.

Sink 是将对象转储到 Stream 的地方。

Sink is where you dump your object into Stream.
