Why is this not working? No text appears in the input field

val inputState: TextFieldValue by mutableStateOf(TextFieldValue())
TextField(value = inputState.value, onValueChange = { inputState = it })

But if I wrap in remember than text input starts working. I am asking because Compose State codelab has examples which have only by mutableStateOf and no remember (for example in ViewModel section), but TextField turns out to be special here?

I think I already wrote you this before, but the codelab should provide all the info you need.
remember is needed if you want to keep the MutableState across recompositions of your `Composable`s. In the ViewModel you do not need it, because the ViewModel is not recomposed and the MutableState is not lost.

Irs not TextField that's special, it's because you're in a composable function. Composable functions get re-invoked (recomposed) whenever anything changes. So in your case, whenever you type a key, it re-invokes your function, which recreates your mutable state with an empty string, and passes that to the TextField composable. You need remember, as florian said, so that the same instance of the state is preserved across compositions.

Florian, thanks. This was the last bit I asked, without a reply, I thought you didn't see it and decided to post here for visibility.

Now I get this: in VM case it stores state, otherwise it is stored in a "compose tree" and I need to ensure it is remembered
