GTIN Toolkit #






A toolkit for validate GTIN's and generate GTIN as well.
This project indeeds to be, stable, easy to use and fast (when possible).
Features #
Actually this library could make something like :


Validate
GTIN including types, SSCC, GSIN, GTIN-14, GTIN-13, GTIN-12, GTIN-8.


Generate Random valid GTIN
Only need give the amount of GTIN digits ex.: for SSCC use 18 digits.


Classify GTIN
Return type using length for classify SSCC, GSIN, GTIN-14, GTIN-13, GTIN-12, GTIN-8.


Use Example #

import 'package:gtin_toolkit/gtin_toolkit.dart' as gtinTool;
import 'package:test/test.dart';

void main() {
test('All methods are being exported correctly', () {
// Generating a valid GTIN number with 12 digit length
String validGtin = gtinTool.generateGTIN(gtinLength: 12);
// make error replacing two right number with 1
String invalidGtin = validGtin.padRight(10).padRight(13, '1');

List<int> validGtinArray = validGtin.split('').map(int.parse).toList();
List<int> invalidGtinArray = invalidGtin.split('').map(int.parse).toList();

expect(gtinTool.parseAndValidate(validGtin), true);
expect(gtinTool.isValidGTIN(validGtinArray), true);

expect(gtinTool.parseAndValidate(invalidGtin), false);
expect(gtinTool.isValidGTIN(invalidGtinArray), false);

expect(gtinTool.generateGTIN().length, 14);
expect(gtinTool.classifyGTIN(validGtin)['name'], 'GTIN-12');

expect(true, true);
});
}
