如何从不同的函数中发出流量值? Kotlin协程 [英] How to emit Flow value from different function? Kotlin Coroutines

问题描述

我有一个流程:

val myflow = kotlinx.coroutines.flow.flow<Message>{}

并希望使用以下函数发出值:

and want to emit values with function:

override suspend fun sendMessage(chat: Chat, message: Message) {
    myflow.emit(message)
}

但是编译器不允许我这样做，是否有任何解决方法来解决此问题?

But compiler does not allow me to do this, is there any workarounds to solve this problem?

推荐答案

Animesh Sahu的答案非常正确.您还可以返回渠道作为流(请参见 consumeAsFlow 或 asFlow 在

The answer of Animesh Sahu is pretty much correct. You can also return a Channel as a flow (see consumeAsFlow or asFlow on a BroadcastChannel).

但是还有一个叫做 StateFlow 的东西正在开发中由Kotlin团队提供，部分目的是实现类似的行为，尽管尚不清楚何时准备就绪.

But there is also a thing called StateFlow currently in development by Kotlin team, which is, in part, meant to implement a similar behavior, although it is unknown when it is going to be ready.
