extractGS1Values method
Splits a gs1 code into its GS1Details. If type is GS1Type.unknown returns [].
Implementation
List<GS1Description> extractGS1Values(String gs1, GS1Type type) {
if (type == GS1Type.unknown) return [];
final onlyDigits = gs1.replaceAll(_everythingExceptDigits, '');
final digits1to4 = onlyDigits.substring(0, 4);
final rest = onlyDigits.substring(4);
return [
GS1Description(digits1to4, _GS1Values.digits1To4[digits1to4]),
GS1Description(rest, _GS1Values.assetIdentifier),
];
}
