# validable
[](https://github.com/devscast/validable/actions/workflows/build.yaml)
Validable is an extensible library that simplifies text field validation for Jetpack Compose and
Compose Multiplatform by providing abstraction and reusable validation logic.
This is what it looks like :
```kotlin
@Composable
fun MyScreen() {
val emailField = remember { EmailValidable() }
// pass all fields to the withValidable method
val validator = rememberValidator(emailField)
TextField(
value = emailField.value,
onValueChange = { emailField.value = it }, // update the text
isError = emailField.hasError(), // check if the field is not valid
)
AnimatedVisibility(visible = emailField.hasError()) {
Text(
text = emailField.errorMessage ?: "",
modifier = Modifier.fillMaxWidth(),
style = LocalTextStyle.current.copy(color = MaterialTheme.colors.error)
)
}
Button(
// a state to check if all fields are valid, without submitting the form
enabled = validator.isValid,
onClick = {
validator.validate {
// will be executed if all fields are valid
Toast.makeText(context, "All fields are valid", Toast.LENGTH_SHORT).show()
}
}
) {
Text(text = "Submit")
}
}
```
