Would it be posible to include ``` suspend fun lt T gt Flow lt T gt first = take 1 single ``` In the flow API

I see I just read `NULL` as `null` and it confused me while reading the code Thank you

maybe they should rename that constant to UNDEFINED laughing

Would it be posible to include ``` suspend fun lt T gt Flow kotlinlang #coroutines

Would it be posible to include:

suspend fun <T> Flow<T>.first() = take(1).single()

In the flow API?

first() already exists in 1.3.0-RC2

the implementation

It's in this file on the library: https://github.com/Kotlin/kotlinx.coroutines/blob/ef696a0bcbaedce53e3c2abd70910275f62315f4/kotlinx-coroutines-core/common/src/flow/terminal/Reduce.kt

Thank you, for some reason I didn't check the RCs

With this implementation this will not work with

flows

that accept nullable values, right?

Icaro Temponi

yeah, should work

No problems here

I see, I just read

NULL

null

and it confused me while reading the code. Thank you

That would be a good idea 😂
