axiy

English summary. Small, dependency-free Dart utilities from the Axiy team. It works in any Dart or Flutter app. The first one is an email validator: isValidEmail answers yes or no, and validateEmail returns an EmailError that says why an address was rejected, so a form can show a precise message. The rest of this page is in Uzbek.

Emailni tekshirish

import 'package:axiy/axiy.dart';

isValidEmail('[e-mail]'); // true
'ali@axiy'.isValidEmail; // false

switch (validateEmail(email)) {
  case null:
    print('To\'g\'ri');
  case EmailError.missingAt:
    print('"@" belgisi yo\'q');
  case EmailError.invalidDomain:
    print('Domen noto\'g\'ri, masalan: axiy.uz');
  case final error:
    print('Email noto\'g\'ri: ${error.name}');
}

Flutter formasida:

TextFormField(
  validator: (value) =>
      isValidEmail(value ?? '') ? null : 'Email noto\'g\'ri',
)

Qoidalar

validateEmail RFC 5321 ning keng tarqalgan [e-mail] ko'rinishini qabul qiladi:

• butun manzil 254, @ dan oldingi qism 64 belgidan oshmaydi;
• @ dan oldingi qism: harf, raqam va !#$%&'*+/=?^_`{|}~- belgilari, nuqta boshida, oxirida yoki ketma-ket kelmaydi;
• domen kamida ikki qismdan iborat (axiy.uz), har bir qism 1–63 belgi, harf, raqam va - (boshida yoki oxirida emas), oxirgi qism faqat harflardan (kamida 2 ta).

Bo'sh joylar kesilmaydi (' [e-mail]' noto'g'ri), shuning uchun kerak bo'lsa avval trim() qiling. Qo'shtirnoqli nomlar ("a b"@x.uz), IP domenlar (a@[127.0.0.1]) va lotin bo'lmagan harflar qabul qilinmaydi. Manzil haqiqatan mavjudligini bilish uchun unga xat yuborib tasdiqlating.

EmailError qiymatlari: empty, tooLong, missingAt, emptyLocalPart, localPartTooLong, invalidLocalPart, emptyDomain, invalidDomain.
