getObjectList<T> method

Implementation

List<T>? getObjectList<T>(
  String key,
  T Function(Map<String, dynamic> json) fromJson, {
  List<T>? defValue = const [],
}) {
  try {

    if (encodedList == null || encodedList.isEmpty) return defValue;

    final List<T> decodedList = encodedList
        .map((str) => jsonUtil.fromJson<T>(str, fromJson))
        .whereType<T>()
        .toList();

    return decodedList;
  } catch (e, stackTrace) {
    logger.e("SpUtil error reading object list for key '$key': $e\n$stackTrace");
