}
,

...
  ),
  error = "my error text",
  onValid = {
 validText ->

Using the Validation Object

Error message for each validation condition
val phoneNumberValidator = TextInputValidator(
  defaultString = "My default text",
  validators = listOf(

{
 text -> (text.length > 12) to "Length must be greater than 12"
}
,

{
 text -> text.startsWith( + ) to "Input must start with  + "
}
,

...
  ) )
Single error message
val phoneNumberValidator = TextInputValidationObj(
  default = "My default text",
  error = "Please enter a valid phone number",
  validators = listOf(

{
 text -> text.length > 12
}
,

{
 text -> text.startsWith( + )
}
,

...
  ) )  myinput.validate(phoneNumberValidator){
 validText ->
  // do something with the valid text 
}

Validate input After setting the validation object on the TextInputLayout you can validate it anywhere on your code
