How to use

// Create a validator with Builder pattern
val emailValidator = Validator.Builder()
    .addRules(
        ValidatableRule.Email("Enter valid mail address"),
        ValidatableRule.Required("Email is required", NotifyType.ON_FOCUS_CHANGE),
        ValidatableRule.Required("Email is required", NotifyType.ON_FORM_SUBMIT),
        ValidatableRule.Email("Enter valid mail address", NotifyType.ON_FORM_SUBMIT),
    )
    .addCollector { validator ->
        mBinding.txtInputEmail.editText?.doOnTextChanged { text, _, _, _ ->
            validator.input = text.toString()
        }
        mBinding.txtInputEmail.editText?.setOnFocusChangeListener { _, isFocused ->
            validator.isFocused = isFocused
        }
    }
    .onValidate { isValid, errorMessage, notifyType ->
        Log.d(
            "Validator",
            "notifyType: $notifyType, isValid: $isValid, errorMessage: $errorMessage"
        )
        mBinding.txtInputEmail.error = errorMessage
    }
    .build()

Or you can write a custom ValidatableRule

class PasswordConfirmRule(
    override val errorMessage: String,
    override val notifyType: NotifyType,
    val originalInputGetter: () -> String
) : BaseValidatableRule(
    errorMessage = errorMessage,
    notifyType = notifyType,
    rule = { it == originalInputGetter.invoke() }
)

// Usage
val passwordConfirmValidator = Validator.Builder()
    .addRules(
        PasswordConfirmRule(
            errorMessage = "Passwords does not match",
            notifyType = NotifyType.ON_VALUE_CHANGE,
            originalInputGetter = { mBinding.txtInputPassword.editText?.text.toString() },
            )
        )
        ...
