Just be careful, think of derivedStateOf just as you would mutableStateOf in a sense that it needs to be remembered! Otherwise this isn't remembered and in case of recomposition will just be called again from scratch. And overall it feels like your explanation on derivedStateOf could be improved a bit. You didn't mention anything about how it implicitly "subscribes" to the state objects that are being accessed in there, but doesn't have any mechanism to update itself when non-state objects are being read in its lambda are changed so it would then show stale data. I really suggest people to read the excellent documentation on these, it does a great job explaining with examples how they work.

Thanks for this! Although my mind couldn't absorb any of the discussed effect. Part 1 to 9 is clear and easy to follow as a newbie of Jetpack Compose. This part (Part 10) doesn't have any relevance in almost all discussed subjects in parts 1 to 9 that's why I couldn't comprehend. Maybe this should be moved in a more advanced playlist for compose. I will just skip to the next part hopefully I am not totally lost as I really love the tutorials. I'll take note on this effect handlers and when I got to the point when I already need this subject then I'll just get back here. Thanks Philipp! Cheers!

Sadly, all `SideEffect` examples strive to be so oversimplified, that neither of them actually demonstrates the real use case of it. Like: what would happen if you do this call without wrapping in `SideEffect`? This effect handler deserves better example.

So was I, but you can usually get the answers in the comments. This is a response from @tetsuoshiva: When you create a new Compose project, it creates a theme named "[ProjectName]Theme". Chances are the project was named "EffectHandlers", and "EffectHandlersTheme" is the theme that was created at project creation. Just write your project name instead of "EffectHandlers", followed by "Theme".

Hi Phillipp!! As always, top notch videos! Thank you! I have a question, I have a Composable function that creates a JFreeChart object which basically gets recomposed when ever its DataSet values are updated. But in that case, the entire JFreeChart object gets recreated again and again with each recomposition. So it appears to be a side effect. Is LaunchedEffect the more accurate choice to prevent that? Do I create the JFreeChart object with key1 = true and then simply let it observe its DataSet updates? Thanks!
@testg4andmmm129

This side effect makes me think twice whet i should use this or maui csharpmarkup. Compose makes it so much complicated especially in example. Why not make normal oop. İnstead of frp in order to conpansate for downside of functional programming, they added remember state etc. How to cover a hole with another thing that also has a hole. Total bullshit..

In my opinion, 19:00 is missing the point. produceState() uses LaunchEffect in the background so that's another difference. And basically the example with the flow constructor seems to be breaking the core principles of compose, it seems like it's doing backwards writes, you are going to end up with infinite recompositions. Saying this as someone who is trying to wrap my head around Compose. :D

The launch effect block is executed once, so it subscribes to the flow once. But once a subscription is established the collect block will trigger with each event

@PhilippLackner In the LaunchedEffectAnimation example. How can `counter` change? It’s just an Int parameter and is never assigned to. Would the example work the same if the first argument to LaunchedEffect were `true`? Great videos, by the way; I’m working my way through the original Compose series and have learned a lot.

Hi Philipp, awesome video, thanks for the great content! Just a question, how would you implement a snackbar call after navigation? when i perform an action, the app navigates up and need to show a snackbar, but i am just not being able to do it... how would you do it?
@PhilippLackner

Have it in a launched effect block in the screen you're navigating to if it should always show up or based on some kind of nav parameter
@12Playmobil
2 жыл бұрын
What you can also do is have a scope = rememberCoroutineScope and a scaffoldState = rememebreScaffoldState in your App() composable and a Scaffold. Your composables should expect a showSnackbar: (String, SnackbarDuration) -> Unit parameter, that you can call (for example when navigating up) like showSnackbar ("Your snack message", SnackbarDuration.Short). Your navigation composable should expect the same function parameter so you can just pass it on to your actual screen composables when creating the instances. In the end your Scaffold in App can look like this: Scaffold( .. state= scaffoldState .. ) { .. YourNavigationComp( navHost =... showSnackbar = { message, duration -> scope.launch { scaffoldState.showSnackbar(message, duration) } }) } With this solution you have a snackbarScope scoped to the App() so your snackbar is still visible during navigation and in the new screen. (Obviously if you need a snackbar scoped to your screen you can implement the scope and Scaffold there). Hope I could explain it well and could help.
