I need a way to do this in view model with coroutines.
Observable.interval(0, 1, TimeUnit.MINUTES)
When I leave the page, the task should be dismissed.
Any suggestions?

A plain while loop with delay or flow { emit(delay(60_000)) } are ways to do this I guess.

Just elaborating on Louis suggestion, maybe something like this could work? (and I’m assuming you’re looking for something that emits a monotonically increasing number starting from 0L spaced evenly as defined by the interval period)

fun <T> Flow<T>.interval(initialDelay: Long, period: Long, unit: TimeUnit = TimeUnit.MILLISECONDS) = flow {
    coroutineScope {
        delay(unit.toMillis(initialDelay))
        var value = 0L
        while (true) {
            emit(value++)
            delay(unit.toMillis(period))
        }
    }
}
