If I call `delay` or any other blocking operation ...

If I call delay or any other blocking operation inside the collect block of a Flow, the next value will not be collected until that delay is over right? So I can't get race conditions between successive emissions of the Flow?

Yes, `Flow`s are very strictly sequential.

thank you

Isn't it dependent on the dispatcher?

[Paul Woitaschek]

If you collect on the io dispatcher imo you can get concurrent emissions

[Dominaezzz]

Dispatcher only affects which thread it runs on. The collectors have checks to make sure emission stay sequential (and other nice safe things).

And that ^^^ is one of the main strengths of 'suspend' behavior. Regardless of the dispatcher's number of threads, it guarantees that code can be called sequentially. 😃
