Validator is a Dart package that provides simple and convenient methods to validate common input data such as emails, URLs, and IP addresses. This package can be particularly useful in situations where you need to validate user input in your Flutter application.
- Email validation: Checks whether a given string matches the standard format for an email address.
- URL validation: Determines whether a given string is a well-formed URL.
- IP Address validation: Validates that a string is a correctly formatted IP address, supporting both IPv4 and IPv6 formats.
- Digits validation: Checks whether a string only contains digits, optionally validating decimals and fractions.
- Alphanumeric validation: Checks whether a string only contains alphanumeric characters, optionally including spaces.
- Password strength validation: Validates the strength of a password, ensuring it contains a mix of characters and is of sufficient length.
- Credit Card validation: Checks whether a given string matches the format for a credit card number.
- Flutter: For installing Flutter and setting up the Dart SDK, follow the instructions provided on the Flutter website.
- Dart: Ensure you have the Dart SDK installed and setup. If you have installed Flutter, Dart should already be installed.

You can use the methods provided by the Validator class to validate emails, URLs, and IP addresses:
import 'package:validator_regex/validator_regex.dart';
// For Email
bool isEmailValid = Validator.email('[email protected]');
// For URL
bool isUrlValid = Validator.url('https://www.test.com');
// For IP Address
bool isIpValid = Validator.ipAddress('192.168.1.1'); //IPv4
// For Digits
bool areDigitsValid = Validator.digits('123', whole: true);
// For Alphanumeric
bool isAlphanumericValid = Validator.alphanumeric('abc123', withSpace: false);
// For Password
bool isPasswordValid = Validator.moderatePassword('Passw0rd!');
// For Credit Card
bool isCardValid = Validator.creditCard('4111111111111111');
