I'm looking for an equivalent method of EditText's InputFilter in Jetpack Compose TextField.
Because I'm trying to prevent users input unwanted values like %@*()-
characters for example.
There is a solution with Regex here:
@Composable
fun FilteredTextField(
text: String,
onChanged: (String) -> Unit,
ignoredRegex: Regex
) {
TextField(value = text,
onValueChange = {
if (!it.contains(ignoredRegex)) onChanged(it)
}
)
}
Using:
@Composable
fun FilteredTextFieldDemo() {
var text by remember { mutableStateOf("") }
FilteredTextField(
text = text,
onChanged = { text = it },
ignoredRegex = Regex("[%@*()-]")
)
}
