If I have a flow of some completion progress, that doesn't ever self terminate. Say flowOf(0.0, 0.5, 0.99, 1.0, 1.0, 1.0, 1.0, 1.0, ...) Is there a nice operator to terminate after the first complete signal? Effectively flowOf(0.0, 0.5, 0.99, 1.0) , results are actually a data class with other interesting data, not a float.

Sure, but a simple conditional check (it != 1.0) will omit the first 1.0 value.

I want one more after it.

I'm about to write my own stateful operator for this.

Thanks, transformWhile wasn't obvious, but great idea.
