validable
Validating text fields when using jetpack compose can sometimes be challenging and verbose.
Validable is an extensible library that allows you to validate your text fields in a simpler way while having a reusable code.
This is what it looks like :
@Composable
fun MyScreen() {
val emailField = remember { EmailValidable() }
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(onClick = {
// pass all fields to the withValidable method
withValidable(emailField) {
// will be executed if all fields are valid
Toast.makeText(context,"All fields are valid",Toast.LENGTH_SHORT).show()
}
}) {
Text(text = "Submit")
}
}
