With the release of Ktor 2.0, one of the migrations I had to do was for Firebase Authentication which I first learned about how to use with Ktor 1.6 from this medium article last year. Learn how to setup Firebase Authentication with Ktor 2.0 and how to test it.
If you have ever shipped a feature with a scrolling list, a product manager will usually ask you to track when an item in that list is viewed by the user. With Jetpack Compose being somewhat new, I was curious how to solve this problem with respect to a LazyColumn so let's learn how to know the second eyeballs see items as they scroll into view!
I was perusing Reddit the other day when someone asked how they could use SavedStateHandle with a StateFlow similar to the SavedStateHandle.getLiveData() version. The most upvoted comment originally was saying that this functionality is not officially supported, but one could convert the LiveData to a Flow using the LiveData.asFlow() extension function. That seemed pretty simple for anyone to do, however testing that would then require using LiveData in your tests which might be annoying if you were using StateFlow to manage state. So after looking over the API, it seemed pretty simple to write a wrapper that could expose this functionality directly as a StateFlow and that is how the SavedStateFlow library was made!
