Hello. I have an OutlinedTextField, Text and Button. In onValueChange I save input value and on Button click call a viewModel method which may result in error, which I show in Text. How can I hide the error Text when onValueChange is triggered once more?

Create a Boolean variable and remember it.
val isError by remember { mutableStateOf(false) }
Then show error text if it's true.
if(isError) {
Text(errorText)
}
You can set it to false in onValueChanged and true when there's an error from ViewModel

I tried that, but it doesn’t work because there is a variable through which I get the info that viewModel method ended with error and it stays true up until the viewModel call is made again.

isError = false in onValueChange happens before it is changed in if (screenState.isErrorVisible) { isError = true }

resolved by transfer of isError in viewModel
