Avoid launchIn
这段代码:
events.filterIsInstance<CloseClicked>()
.onEach { navigator.goTo(Finish()) }
.launchIn(coroutineScope)
可以替换成:
coroutineScope.launch {
events.first { it is CloseClicked }
navigator.goTo(Finish())
}
或者:
coroutineScope.launch {
events.filterIsInstance<CloseClicked>()
.collect { navigator.goTo(Finish()) }
}

作者做了一个例子来探索这个方案: https://github.com/hitherejoe/minimise
