Description:

isbn

A library for parsing, validating, and generating ISBN codes easily.
Supports ISBN-10 and ISBN-13 formats.
This library is designed to have minimal dependencies for use across multiple platforms.
Using #
The easiest way to use this library is via the top-level Isbn class.
import 'package:isbn/isbn.dart';

/// This example illustrates the main features of the library
///
/// For more examples, look at /tests
void main() {
/// Initialize the main object
Isbn isbn = Isbn();

/// Check if a string is in ISBN-10 format
print(isbn.isIsbn10('ISBN 4-19-830127-1'));

/// Check if a string is in ISBN-13 format
print(isbn.isIsbn13('ISBN 97818nope4677'));

/// Convert a string into ISBN 10 format
print(isbn.toIsbn10('isbn 0-8264-9752-7'));

/// Convert a string into ISBN 13 format
print(isbn.toIsbn13('record: isbn 0-8264-9752-7'));

/// Parse text for ISBNs
/// Specify detection levels to use. Options: [loose, normal, strict]
final text = r'ISBN 9781849284677'
'data: 9780312640583 thisworks'
'record: isbn 978-0312640583'
'also works: isbn 978031264058 3';
print(isbn.getIsbnFromString(text, level: 'normal'));

/// Convert a string to its canonical ISBN representation
print(isbn.toCanonical('978-03126-4058-3'));

/// Convert a string to EAN13 format
print(isbn.toEAN13('978-03126-4058-3'));

On ISBNs #
ISBN stands for International Standard Book Number. It is a unique identifier used for books
and other related products like e-books, audiobooks, and certain multimedia publications.
ISBNs are used to uniquely identify a specific edition or format of a book and are an
essential part of the book supply chain and publishing industry.
The standard ISBN format is now 13 digits. However, the older ISBN-10 system is still
encountered in some older publications. The ISBN-10 system was in use until 2007, after which the
ISBN-13 system became the standard.
The ISBN-13 format is also known as EAN-13 (European Article Number), as it shares the
same structure with EAN-13 barcodes used for other retail products.
