addAlternativePhoneMasks static method

void addAlternativePhoneMasks({ required String countryCode, required List<String> alternativeMasks, bool mergeWithExisting = false, })

adds a list of alternative phone maskes to a country data. This method can be used if some mask is lacking countryCode must be exactrly 2 uppercase letters like RU, or US or ES, or DE. alternativeMasks a list of masks like '+00 (00) 00000-0000', '+00 (00) 0000-0000' that will be used as an alternative. The list might be in any order mergeWithExisting if this is true, new masks will be added to an existing list. If false, the new list will completely replace the existing one

Implementation

static void addAlternativePhoneMasks({
  required String countryCode,
  required List<String> alternativeMasks,
  bool mergeWithExisting = false,
}) {
  assert(alternativeMasks.isNotEmpty);
  final countryData = _findCountryDataByCountryCode(countryCode);
  String currentMask = countryData['phoneMask'];
  alternativeMasks.sort((a, b) => a.length.compareTo(b.length));
  countryData['phoneMask'] = alternativeMasks.first;
  alternativeMasks.removeAt(0);
  if (!alternativeMasks.contains(currentMask)) {
    alternativeMasks.add(currentMask);
  }
  alternativeMasks.sort((a, b) => a.length.compareTo(b.length));
  if (!mergeWithExisting || countryData['altMasks'] == null) {
    countryData['altMasks'] = alternativeMasks;
  } else {
    final existingList = countryData['altMasks'];
    alternativeMasks.forEach((m) {
      existingList.add(m);
    });
  }
  // if (kDebugMode) {
  //   print('Alternative masks for country "${countryData['country']}"' +
  //       ' is now ${countryData['altMasks']}');
  // }
}
