如何使用built_value包使用Map<String和dynamic>进行序列化

dependencies:
  built_value: ^7.1.0
  built_collection: ^5.0.0

import 'package:built_value/built_value.dart';
import 'package:built_value/serializer.dart';

part 'my_data.g.dart';

abstract class MyData implements Built<MyData, MyDataBuilder> {
  String get name;
  int get age;
  Map<String, dynamic> get data;

  MyData._();

  factory MyData([void Function(MyDataBuilder) updates]) = _$MyData;

  static Serializer<MyData> get serializer => _$myDataSerializer;
}

import 'package:built_value/serializer.dart';
import 'my_data.dart';

void main() {
  final data = MyData((b) => b
    ..name = 'John'
    ..age = 25
    ..data = {'key': 'value'});

  // 序列化
  final serialized = serializers.serialize(data);
  print(serialized); // 输出：{name: John, age: 25, data: {key: value}}

  // 反序列化
  final deserialized = serializers.deserialize(serialized,
      specifiedType: const FullType(MyData));
  print(deserialized.name); // 输出：John
  print(deserialized.age); // 输出：25
  print(deserialized.data); // 输出：{key: value}
}
