A complete new dependencies just to do simple core things?? Like new dependency just for extention functions for suspend instead of callback I know it because of kotlin support and java the main one, but why not make single dependency for kotlin for all that things instead of kotlin support dependency for every core feature like coroutines I think android team should think in better way

Because kotlin != android

I thought any state is discarded once the composable is disposed of !

@PhilippLackner Жыл бұрын

The state is, but the underlying flow will still run because collectAsState will not cancel it when the app goes in the background

I dont understand why jetpack Compose developers dont just use mutableStateOf in ViewModel so we dont need to use collect at UI

ok I have a question. When ur app then goes to the foreground after being in the background, this thing gets notified and update the state, how can I prevent this ? Say I have a snackbar that I have already shown, and i don't wan to show it anymore when the app goes to the foreground

@dennispetcu8383 Жыл бұрын

Dismiss the snackbar in onPause

@Philipp there is a question that came up in my mind when I was dealing with saving UI state, should we use rememberSaveable or ViewModel's saved state handle? 🤔

@WellingtonFerreiraTon Жыл бұрын

If you don't mind me trying to help, I guess rememberSaveable is better to use when we want a ui state that is intrinsically connected to composable (for example, an expandable text, to keep if it's expanded or not even after configuration changes); and UI logic that relates to business logic we can keep on view model (for example, when we populate a list of users to a composable from request or database). I hope it helps. (If i wrote anything wrong please let me know, english is not my native language)

@@WellingtonFerreiraTon Thanks for the reply, but i don't agree on the second statement about using savedstatehandle for saving lists, it is not recommended (according to the docs), we could use a local database for that.

@WellingtonFerreiraTon Жыл бұрын

@@khiariyoussef3226 sorry I was speaking about state management on the second statement, not about saved state handle. My bad! I think the most frequent use case for saved state handle is to get arguments defined through navigation. Google reccomends to use view model mostly for UI logic that depends on business logic. If possible the best approach is to have a state class to handle most complex use cases that don't rely on business logic. I hope I got this right. Thanks for your input :)

Just a little addendum, view model is also reccomended for screen logic.

Complex things and concepts allow to create versatile software and API. If someone quits from Android development due to "complex" things like this, they've never been an accomplished engineer at first.
