Kotlin 流入 Java

Question

I have been trying to find some good resources that point to Kotlin Flow usage/integration in java applications but I couldn't find any. Can we use Kotlin Flow (SharedFlow/StateFlow) in Kotlin based applications that might be integrated in other Java based projects.

Answer 1

Technically, you can use any Kotlin APIs from Java, including flows and coroutines.

In practice , any attempt to use Flows directly from Java is likely to be so difficult to do correctly that you shouldn't bother trying. So don't. Instead, write Kotlin APIs that expose a non-coroutine API and wrap flows, and then use those from Java if you must.
