String Validation Extension [New Feature]
This package provides an extension on String? that offers convenient methods for validating various input formats using the AutoValidate class. It allows for a more readable and fluent validation process in your Dart applications.
Features
Validate usernames, passwords, email addresses, phone numbers, credit card numbers, and more.
Check for valid formats like ISBN, MAC addresses, hexadecimal codes, and JSON Web Tokens (JWT).
Simplify validation checks by using fluent methods directly on String? instances.
Improve code readability and maintainability by using the extension methods for validation.
import'package:auto_validate/auto_validate.dart';
voidvalidation() {
var email = 'Dev.M.ElShenawy@Icloud.com';
var name = 'Mahmud El Shenawy';
var password = '@MahmoudElShenawy2021';
var phone = '+201098415860';
// You can validate the input using the AutoValidate classAutoValidate.email(email.toString())
? print('Email is Valid')
: print('Email is Invalid');
AutoValidate.userName(name.toString())
? print('User Name is Valid')
: print('User Name is Invalid');
AutoValidate.password(password.toString())
? print('Password is Valid')
: print('Password is Invalid');
AutoValidate.phone(phone.toString())
? print('Phone is Valid')
: print('Phone is Invalid');
// You can also use the extension methods to validate the input
email.isValidEmail
? print('Email is Valid')
: print('Email is Invalid');
name.isValidUsername
? print('User Name is Valid')
: print('User Name is Invalid');
password.isValidPassword
? print('Password is Valid')
: print('Password is Invalid');
phone.isValidPhone
? print('Phone is Valid')
: print('Phone is Invalid');
