deserialize method
Interface for intput serialization.
Implementation
@override
void deserialize(SerializableInput input) {
keys.clear();
int length = input.getUint32();
for (int i = 0; i < length; i++) {
Uint8List key = deserializeStringBytes(input);
keys.add(MapEntry<Uint8List, String>(key, deserializeString(input)));
}
}
