I'm using

Observable.interval

to count down from 30 seconds to zero. After that, I want to use

flatMap

and continue another Rx chain. I'm not sure what the best way is to actually know when

after that

is. Using

flatMap

directly after the

interval

call obviously doesn't work since the

flatMap

gets called after each tick of the interval. RIght now I'm using

materialize

and checking if the notification

isOnComplete

. Is that the best way to handle this?

Maybe you’re looking for

timer

instead?

if you want to accumulate a value

scan

might help too.

It looks like

Timer

only emits once the timer finishes, which is not what I want since I'm using the values that

interval

produces.

scan

seems unnecessary in conjunction with

interval

...I could theoretically use both

interval

and

timer

in two different chains to accomplish this

Maybe

concatWith()

?

Oh that's perfect
