phone_numbers_parser

Phone Numbers Parser

Dart library for parsing phone numbers. Inspired by Google's libphonenumber and PhoneNumberKit for ios.

The advantage of this lib instead of libphonenumber is that it instantly supports all platforms (no need for channeling).

Features

• Validation: Validate based on type (mobile, fixed line, voip)
• Formatting: Format phone number for a specific country
• Phone ranges: find all phone numbers in a range of phone numbers
• Find phone numbers in a text
• Supports eastern arabic digits
• Uses best-in-class metadata from Google's libPhoneNumber project.

Usage

Use the class PhoneNumber as a starting point

import 'package:phone_numbers_parser/phone_numbers_parser.dart';

void main(List<String> arguments) {
  final frPhone0 = PhoneNumber.parse('+33 655 5705 76');
  // raw caller in france calling another person in france
  final frPhone1 =
      PhoneNumber.parse('0 655 5705 76', callerCountry: IsoCode.FR);
  // us calling to france
  final frPhone2 =
      PhoneNumber.parse('011 33 655-5705-76', callerCountry: IsoCode.US);
  final frPhone3 =
      PhoneNumber.parse('011 33 655 5705 76', destinationCountry: IsoCode.FR);
  final isAllEqual =
      frPhone0 == frPhone1 && frPhone0 == frPhone2 && frPhone0 == frPhone3;
  print(frPhone1);
  print('all raw same: $isAllEqual');

  // validation
  final valid = frPhone1.isValid();
  final validMobile = frPhone1.isValid(type: PhoneNumberType.mobile);
  final validFixed = frPhone1.isValid(type: PhoneNumberType.fixedLine);
  print('valid: $valid'); // true
  print('valid mobile: $validMobile'); // true
  print('valid fixed line: $validFixed'); // false

  // utils
  final text =
      'hey my phone number is: +33 939 876 218, but you can call me on +33 939 876 999 too';
  final found = PhoneNumber.findPotentialPhoneNumbers(text);
  print('found: $found');
}

validation

final valid = frPhone1.validate();
final validMobile = frPhone1.validate(type: PhoneNumberType.mobile);
final validFixed = frPhone1.validate(type: PhoneNumberType.fixedLine);
print('valid: $valid'); // true
print('valid mobile: $validMobile'); // true
print('valid fixed line: $validFixed'); // false

Formatting

Formatting is region specific, so the formats will vary by iso code to accommodate for local formats.

final phoneNumber =
    PhoneNumber.parse('2025550119', destinationCountry: IsoCode.US);
final formattedNsn = phoneNumber.formatNsn();
print('formatted: $formattedNsn'); // (202) 555-0119

Range

print('Ranges:');
final first = PhoneNumber.parse('+33 655 5705 00');
final last = PhoneNumber.parse('+33 655 5705 03');
final range = PhoneNumber.getRange(first, last);

print('Count: ${range.count}');
print('Expand: ${range.expandRange().join(',')}');

if (first > last) {
  print("this shouldn't be.");
}

final one = PhoneNumber.parse('+33 655 5705 01');
final two = PhoneNumber.parse('+33 655 5705 02');

if (one.isAdjacentTo(two)) {
  print('We are together');
}
if (one.isSequentialTo(two)) {
  print('$two comes after $one');
}

/// treat the phone no. like an int
final three = two + 1;
print('Its still a phone No. $three');
two - 1 == one;
final another = one + 2;
print('$another == $three');
