Would it be posible to include:

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

In the flow API?

[Icaro Temponi]

first() already exists in 1.3.0-RC2

[Icaro Temponi]

the implementation

[Icaro Temponi]

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

[Eric Martori]

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

[Eric Martori]

With this implementation this will not work with flows that accept nullable values, right?

[Icaro Temponi]

yeah, should work

[Icaro Temponi]

No problems here

[Eric Martori]

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

[bdawg.io]

maybe they should rename that constant to UNDEFINED 😆

[Icaro Temponi]

That would be a good idea 😂
