Avoid launchIn
這段代碼:
events.filterIsInstance<CloseClicked>()
.onEach { navigator.goTo(Finish()) }
.launchIn(coroutineScope)
可以替換成:
coroutineScope.launch {
events.first { it is CloseClicked }
navigator.goTo(Finish())
}
或者:
coroutineScope.launch {
events.filterIsInstance<CloseClicked>()
.collect { navigator.goTo(Finish()) }
}

- 不好測試.
作者受到這篇文章的啟發(fā), 準備探索一下多個modules項目中, compose導航的解決方案.
作者做了一個例子來探索這個方案: https://github.com/hitherejoe/minimise
強烈推薦這篇文章!!
