Validate IBANs

Usage

A simple usage example:

import 'package:iban/iban.dart';

void main() {
  final iban = 'at61 1904 3002 3457 3201';

  if (isValid(iban)) {
    print('$iban is a valid iban');
  } else {
    print('$iban is not a valid iban');
  }

  if (isValid(iban, sanitize: false)) {
    print('$iban without sanitization is a valid iban.');
  } else {
    print('$iban without sanitization is not a valid iban.');
  }

  print('Convert the IBAN into a standard format: ${electronicFormat(iban)}');
  print('To display an IBAN to a user we have: ${toPrintFormat(iban)}');
}

Iban specifications

The iban specifications are copied from iban.js, which is unfortunately no longer maintained.

See specifications.dart for all available countries.

Contrary to iban.js, which parses the specifications at runtime, all regular expression strings are parsed using specifications_builder.dart.

Please open an issue if you know how to build the iban for another country.
