Hi, my TextField behaves super oddly. It works perfectly in Android but in iOS whenever I enter a character, onValueChange is called multiple times. This only happens if my TextField value exists in ViewModel. If value exists in composable use remember it behaves as expected.

Has anyone faced a similar issue?

I'm not sure, but if you are using StateFlow, make sure you are collecting the flow on the immediate dispatcher. E.g. flow.collectAsState(Dispatchers.Main.immediate).

Hi, that doesn’t help. This is odd since my app works quite alright. Nothing unusual happens until I edit the TextField. After I edit the TextField LaunchEffect(Unit){...} get’s called dozens of time. This also happens if I back up my TextField with var key by _remember_ *{* _mutableStateOf_("") *}* (tried this to verify that recompositions aren’t ducked). In such case input to TextField works alright but afterwards the app doesn’t work right.

It would be nice to see some code, or maybe a reproducer code.

It’s right here:

https://github.com/solita/HRnD/blob/main/HRnD/composeApp/src/commonMain/kotlin/fi/solita/hrnd/feature/list/ListScreen.kt

I’ve added

text: String,
        onSearchUpdate: (String) -> Unit,

to BuildContent function in order to verify if the issue doesn’t come from MVI-Orbit

I couldn't find any issues with the code straightaway. If the issue happens only if the the state is in the ViewModel, then it might also worth asking in #orbit-mvi.

just a guess, maybe try compose-compiler to 1.5.8 and maybe try with TextFieldState , though I am unsure why it wouldn't work now

Turns out iOS TextField is faulty.

disabling animations by
UIView.setAnimationsEnabled(*false*) fixes the issue.

I'd file a bug so that they fix it for everyone. 😄
