({String key, String value})? get getMapGenericType

Implementation

({String key, String value})? get getMapGenericType {
  int start = indexOf('<') + 1;
  int end = lastIndexOf('>');

  if (start >= end) return null;

  List<String> typeList = substring(
    indexOf('<') + 1,
    lastIndexOf('>'),
  ).split(',');
  if (typeList.length != 2) return null;

  return (key: typeList[0].trim(), value: typeList[1].trim());
}
