identifyMultiple static method

Map<String, List<CardType>> identifyMultiple(List<String> cards, { bool validateLength = true, bool useCheck = true, bool ignoreNoise = false, bool handleAnonymization = false, })

A batch identify wrapper on top of identify func

cardNumString The card number to identify.

validateLength Validate the length as part of the String identification. A false value can be useful to identify the fragment of a card number. Default is true.

useCheck Validate the card number as part of the String identification. A false value can be useful to identify the fragment of a card number. The validation will be the issuing network's validation, mostly Luhn. Default is true.

ignoreNoise Ignore common noise found in card number. This noise is any of - .. Default is false.

handleAnonymization Set any non-digits to zero. It is common to use "X" and "#" to hide some digits. Default is false.

var card1 = "2201200000000000";
var card2 = "5110710000901089";
var identifiedCardsMap = FlutterCardidy.Identify([card1, card2]);

returns a map of CardNumber (key) and Identified Card Type (value)

Implementation

  List<String> cards, {
  bool validateLength = true,
  bool useCheck = true,
  bool ignoreNoise = false,
  bool handleAnonymization = false,
}) {
  Map<String, List<CardType>> results = {};
  if (cards.isNotEmpty) {
    for (var cardNum in cards) {
      var identifiedVendors = identify(
        cardNum,
        validateLength: validateLength,
        useCheck: useCheck,
        ignoreNoise: ignoreNoise,
        handleAnonymization: handleAnonymization,
      );
      results.putIfAbsent(cardNum, () => identifiedVendors);
    }
  }
  return results;
