Dart LibPhoneNumber

A Dart package for working with international phone numbers based on Google's libphonenumber implementation. It parses, formats, and validates numbers without relying on native dependencies.

✨ Features

✅ Parse, format, and validate phone numbers [parse(), format(), isValidNumber()]
➝ Convert raw phone numbers into structured objects, apply different formats, and check validity.

✅ Identify phone number types [getNumberType()]
➝ Distinguishes between Fixed-line, Mobile, Toll-free, Premium Rate, VoIP, etc.

✅ Match and compare phone numbers [isNumberMatch()]
➝ Determines whether two numbers are the same or similar.

✅ Generate example phone numbers [getExampleNumber()]
➝ Provides valid phone number examples for various countries/regions.

✅ Perform quick validation [isPossibleNumber()]
➝ Checks if a number has a valid length without requiring region-specific details.

✅ Validate phone numbers for a specific region [isValidNumberForRegion()]
➝ Ensures a phone number is valid in the given country based on length and prefix rules.

✅ Format phone numbers as-you-type [getAsYouTypeFormatter()]
➝ Dynamically formats phone numbers as users enter each digit.

✅ Extract phone numbers from text [findNumbers()]
➝ Detects phone numbers within a block of text (e.g., 'Call me on 0241234567').

✅ Geocode phone numbers [getDescriptionForNumber()]
➝ Retrieves geographical information related to a phone number (e.g., 'Zurich' for a Swiss number).

✅ Retrieve carrier information [getNameForNumber()]
➝ Identifies the telecom provider associated with a number (e.g., 'AT&T', 'Vodafone').

✅ Find associated timezones [getTimeZonesForNumber()]
➝ Returns timezone(s) linked to a phone number (e.g., 'America/New_York').

🚀 Quick Start

📌 Installation

🏗️ Usage

📞 Parse a Phone Number

import 'package:dlibphonenumber/dlibphonenumber.dart';

final PhoneNumberUtil phoneUtil = PhoneNumberUtil.instance;
final PhoneNumber phoneNumber = phoneUtil.parse('0241234567', 'GH');
print('$phoneNumber'); // countryCode: 233, nationalNumber: 241234567

👍 Validate a Phone Number

import 'package:dlibphonenumber/dlibphonenumber.dart';

final PhoneNumberUtil phoneUtil = PhoneNumberUtil.instance;
final PhoneNumber phoneNumber = phoneUtil.parse('0241234567', 'GH');
final bool validPhoneNumber = phoneUtil.isValidNumber(phoneNumber);
print('$validPhoneNumber'); // true

📐 Format a Phone Number

import 'package:dlibphonenumber/dlibphonenumber.dart';

final PhoneNumberUtil phoneUtil = PhoneNumberUtil.instance;
final PhoneNumber phoneNumber = phoneUtil.parse('0241234567', 'GH');

final String e164 = phoneUtil.format(phoneNumber, PhoneNumberFormat.e164);
print('$e164'); // [phone]

final String international = phoneUtil.format(phoneNumber, PhoneNumberFormat.international);
print('$international'); // [phone]

final String national = phoneUtil.format(phoneNumber, PhoneNumberFormat.national);
print('$national'); // 024 123 4567

final String rfc3966 = phoneUtil.format(phoneNumber, PhoneNumberFormat.rfc3966);
print('$rfc3966'); // tel:[phone]

🔢 Identify Number Types

import 'package:dlibphonenumber/dlibphonenumber.dart';

final PhoneNumberUtil phoneUtil = PhoneNumberUtil.instance;
final PhoneNumber phoneNumber = phoneUtil.parse('0241234567', 'GH');
final PhoneNumberType type = phoneUtil.getNumberType(phoneNumber);
print('$type'); // PhoneNumberType.mobile

🔄 Match and Compare Phone Numbers

import 'package:dlibphonenumber/dlibphonenumber.dart';

final PhoneNumberUtil phoneUtil = PhoneNumberUtil.instance;
final PhoneNumber phoneNumber1 = phoneUtil.parse('0241234567', 'GH');
final PhoneNumber phoneNumber2 = phoneUtil.parse('[phone]', '');
final MatchType matchType = phoneUtil.isNumberMatch(phoneNumber1, phoneNumber2);
print('$matchType'); // MatchType.exactMatch

💡 Generate Example Numbers

import 'package:dlibphonenumber/dlibphonenumber.dart';

final PhoneNumberUtil phoneUtil = PhoneNumberUtil.instance;
final PhoneNumber? examplePhoneNumber = phoneUtil.getExampleNumber('GH');
print('$examplePhoneNumber'); // countryCode: 233, nationalNumber: 302345678

👌 Perform Quick Validation

import 'package:dlibphonenumber/dlibphonenumber.dart';

final PhoneNumberUtil phoneUtil = PhoneNumberUtil.instance;
final PhoneNumber phoneNumber = phoneUtil.parse('[phone]', '');
final bool isPhoneNumber = phoneUtil.isPossibleNumber(phoneNumber);
print('$isPhoneNumber'); // true

🌍 Validate Numbers for a Specific Region

import 'package:dlibphonenumber/dlibphonenumber.dart';

final PhoneNumberUtil phoneUtil = PhoneNumberUtil.instance;
final PhoneNumber phoneNumber = phoneUtil.parse('0241234567', 'GH');
final bool isValidRegionNumber = phoneUtil.isValidNumberForRegion(phoneNumber, 'US');
print('$isValidRegionNumber'); // false

🔍 Extract Numbers from Text

import 'package:dlibphonenumber/dlibphonenumber.dart';

final PhoneNumberUtil phoneUtil = PhoneNumberUtil.instance;
final Iterable<PhoneNumberMatch> foundPhoneNumbers = phoneUtil.findNumbers('Call me on 0201234567', 'GH');
print('${foundPhoneNumbers.map((e) => e.number)}'); // [countryCode: 233, nationalNumber: 201234567]

🌍 Geocode a Phone Number

import 'package:dlibphonenumber/dlibphonenumber.dart';

final PhoneNumberUtil phoneUtil = PhoneNumberUtil.instance;
final PhoneNumber phoneNumber = phoneUtil.parse('0241234567', 'GH');
final String territory = PhoneNumberOfflineGeocoder.instance.getDescriptionForNumber(phoneNumber, Locale.english);
print('$territory'); // Ghana

📡 Retrieve Carrier Information

import 'package:dlibphonenumber/dlibphonenumber.dart';

final PhoneNumberUtil phoneUtil = PhoneNumberUtil.instance;
final PhoneNumber phoneNumber = phoneUtil.parse('0241234567', 'GH');
final String carrier = PhoneNumberToCarrierMapper.instance.getNameForNumber(phoneNumber, Locale.english);
print('$carrier'); // MTN
