The ID field verification doesn't pass the validation from the first try
I have the field where user writes the 9-digit number.
The number should have 9 digits and it should pass the Luhn algorithm:
MaterialTextField(
label = formModel.someNumber.placeholder,
text = formModel.someNumber.value,
onTextChange = {
formModel.someNumber.value = it
showError = false
if (it.isSomeNumberValid) {
showSomeNumberError = false
} else {...
