Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

ViewModel: for UI business, not UI operations 😮
If you mean UI events like the events from the Model to the UI, then you can use a sealed class and a Channel or EventEmitter
-
Kotlin Flow implementation of SingleLiveEvent
I can also comment https://github.com/Zhuinden/event-emitter 😛
-
Sending View Model Events to the UI (is this how people are handling Navigation and Snackbars now?)
For events, I use https://github.com/Zhuinden/event-emitter with https://github.com/Zhuinden/live-event
-
What's the proper way of accessing a Composable function from a non-composable one?
I use https://github.com/Zhuinden/event-emitter for this sort of thing via DisposableEffect(Unit) {
-
MVVM and one shot operations
If there isn't multiple screen switches involved, I use https://github.com/Zhuinden/event-emitter
-
LiveData is superior to StateFlow for UI and ViewModel layer.
That's why I wrote EventEmitter and never had a problem.
-
What is your currently configured SharedFlow implementation ?
I use BehaviorRelay in place of MutableStateFlow/MutableLiveData, and I use EventEmitter in place of uh, SingleLiveEvent I guess.
-
LiveData vs SharedFlow and StateFlow in MVVM and MVI Architecture
Well I've been using this which is merely a lifecycle-aware wrapper over this, if you're in Kotlin and you are using coroutine stuff then you can also use Channel(UNLIMITED) with receiveAsFlow()

Any Modern examples of using only 1 activity, but multiple(lots of) fragments in a non trivial app
Not a complex example per say, but I did write this sample and it'd scale as it looks right now, just more packages in core and in features.

How to properly handle conditional navigation with dynamic starting destination whhen using navigation component?
The whole circus around login/logout is a mess in jetpack navigation. It assumes a world where your app always has a fixed starting point which imo doesn't make sense with apps where the entire content is behind auth. I recommend checking out https://github.com/Zhuinden/jetpack-navigation-ftue-sample

LiveData vs SharedFlow and StateFlow in MVVM and MVI Architecture
A simplified variation can be seen in this repo, a LiveData variant with Jetpack stuff can be seen in this repo, my issue with this sample is that as there is no input + debounce + filter + async data load example in it, there is no switchMap (and even for combineTuple, I can use my other helper validateBy here), and those would be key to understanding the difference in terms of expressibility and power...

I'm looking for a good sample codebase to review/learn from that uses MVVM, live data, compose and either dagger or hilt. Any suggestions?
I have a non-Compose "MVVM + Hilt" sample here

Things seem to be shockingly complex in Android dev now
See https://github.com/Zhuinden/jetpack-navigation-ftue-sample/blob/master/app/src/main/java/com/zhuinden/jetpacknavigationdaggersavedstatehandleftueexperiment/features/login/LoginViewModel.kt#L30-L41
-
Hilt alpha 0.0.3
Yes it works wonders
What are some alternatives?
Kotlin_Flow_To_The_View - PoC using Flow completely on an Android Projet with MVVM architecture. No LiveData. The advantage over simply using the viewModelScope is the fact that 5 seconds after leaving the application (not killing it !), the coroutine is cancelled, avoid possibly unnecessary work.
