ComplexEnumCodec<V>.sparse constructor

Implementation

ComplexEnumCodec.sparse(Map<int, MapEntry<String, Codec<V?>>> map)
  : _keyedIndex = {
      for (final entry in map.entries) entry.value.key: entry.key,
    },
    _keyedName = {
      for (final entry in map.entries) entry.key: entry.value.key,
    },
    map = {
      for (final entry in map.entries) entry.value.key: entry.value.value,
    };
