I need to implement a countdown timer in a Glance widget, that should be updated every second. At the bare minimum, every minute.

What would be the best approach for this using Jetpack Compose Glance widgets? First time I play with this.

I’ve been trying to do something like

object : CountDownTimer(startTime, 1000) {
            private var coroutineScope: CoroutineScope? = null

            override fun onTick(millisUntilFinished: Long) {
                if (coroutineScope == null) {
                    coroutineScope = CoroutineScope(coroutineContext)
                }
                coroutineScope?.launch {
                    onTick?.invoke(millisUntilFinished) // calls GlanceWidget.updateAll(context)
                }

            }

            override fun onFinish() {
                coroutineScope?.cancel()
                onFinish?.invoke()
            }
        }
