Hi, faced with crash while using compose version of lib:

I encountered the same issue and I have a possible workaround.

You probably initialise the Emitter using the max() function. emitter = Emitter(duration = 1000, TimeUnit.MILLISECONDS).max(2000)

The issue here is an integer division that clips to 0, tough correct would should be 0.5f. This is the problematic line in the EmiterConfig.kt.

Quick Workaround: The issue does not occur if I use the perSecond() function to initialise the Emitter. emitter = Emitter(duration = 1000, TimeUnit.MILLISECONDS).perSecond(1000)

We have this issue even if we use perSecond

        emitter = Emitter(duration = 2000, TimeUnit.MILLISECONDS).perSecond(50),

Is it reproducible? If so, did you run the memory profiler? Can you reproduce it in a sample project?

Any info you can provide would be helpful.

I can check for some more details, but we get this in Firebase crash reports
