如何在Dart扩展ListBase类中使用json_annotation

import 'dart:convert';
import 'package:json_annotation/json_annotation.dart';

@JsonSerializable(includeIfNull: false)
class MyList extends ListBase<String> {
  final List<String> _list = [];

  @override
  int get length => _list.length;

  @override
  set length(int newLength) => _list.length = newLength;

  @override
  String operator [](int index) => _list[index];

  @override
  void operator []=(int index, String value) {
    _list[index] = value;
  }

  factory MyList.fromJson(Map<String, dynamic> json) => _$MyListFromJson(json);

  Map<String, dynamic> toJson() => _$MyListToJson(this);
}

dependencies:
  flutter:
    sdk: flutter
  json_annotation: ^4.0.0

dev_dependencies:
  flutter_test:
    sdk: flutter
  build_runner: ^2.0.4
  json_serializable: ^4.1.0

flutter pub get

flutter pub run build_runner build

void main() {
  final jsonStr = '["apple", "banana", "cherry"]';

  // 反序列化
  final myList = MyList.fromJson(jsonDecode(jsonStr));
  print(myList); // 输出：[apple, banana, cherry]

  // 序列化
  final json = myList.toJson();
  print(json); // 输出：["apple","banana","cherry"]
}
