State Management in Jetpack Compose Best Practices - Android Studio Tutorial
Рет қаралды 2,244
Күн бұрынState Management in Jetpack Compose is one of the most important things in order to create clean Composables, to separate responsibilities and to always display the right state to the user. In this video we will have a look at the best practices to manage your state. E.g. how to create state, where to create it or when you actually should use ViewModels / state holder classes.

You do an excellent job on these tutorials. Maybe it is just a naming issue, but putting functions like showSnackbar() into a class called "ExampleState" seems like it is not a pure state now, but rather a utility class of sorts. I see what you are trying to do though and I like it - there are visible ui changes due to business logic changes that are reflected in the ViewModel state, and there are other ui changes that are purely ui logistics (like the scaffold state, scroll state, etc.) that you are putting into the ExampleState.

I agree with you the naming could be better here. As from the Googles documentation a state holder (ExampleState in this video) can be seen as a class that extracts logic out of our composables. That includes UI Logic and UI State. With this approach we can make our composables only responsible for emitting UI (drawing, composition and so on) and I think this is a very neat approach in terms of separation of concerns. Triggering the snackbarhoststate.showSnackbar is UI Logic and thus can be put inside a state holder class. But maybe I haven't highlighted enough that such a plain state holder class does not only contain UI State but can also be responsible for UI logic.

I could be wrong but list.toMutableList().add(0,"C") at 8:50 should not modify the original list anyway.

Oh yeah true but it does not change the problem , you can try it with mutableList when .add actually inserts the element.
