When I am collecting how do I cancel a flow, I gotta throw an error?

Throw a cancellation exception. Or call cancel if it's available in your context.

Cancel the collector

[Luis Munoz]

merge(sampling(), samplingCheckFlow()).flowOn(context)
private fun samplingCheckFlow() : Flow<String> {
  return flow<String> {
    <http://Log.info|Log.info>().log("cehcking flow!")
    while(isSampling.get()) { delay(1000L) }
    <http://Log.info|Log.info>().log("[kafka sampling] - throw cancellation")
    throw CancellationException("not sampling")
  }
}

[Dominaezzz]

You're not collecting the flow.

thanks guys, I didn't ask the question correctly by not showing details but my mistake was I was doing .first() instead of .toList().first() in my test case
