# iban

Validate IBANs

![Build Status](https://travis-ci.org/close2/iban.svg?branch=master)

## Usage

A simple usage example:

```dart

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specifications are copied from [iban.js](https://github.com/arhs/iban.js/blob/master/iban.js), which is unfortunately no longer maintained.

See [specifications.dart](tool/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](tool/specifications_builder.dart).

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