Flutter:如何对列表中的对象进行JSON解析

dependencies:
  flutter:
    sdk: flutter
  json_annotation: ^4.0.1
  json_serializable: ^4.3.0

import 'package:json_annotation/json_annotation.dart';

part 'object_model.g.dart';

@JsonSerializable()
class ObjectModel {
  final String name;
  final int age;

  ObjectModel({required this.name, required this.age});

  factory ObjectModel.fromJson(Map<String, dynamic> json) =>
      _$ObjectModelFromJson(json);
  Map<String, dynamic> toJson() => _$ObjectModelToJson(this);
}

flutter pub run build_runner build

import 'dart:convert';

List<ObjectModel> parseObjects(String jsonString) {
  final parsed = jsonDecode(jsonString).cast<Map<String, dynamic>>();
  return parsed
      .map<ObjectModel>((json) => ObjectModel.fromJson(json))
      .toList();
}

String json = '[{"name":"John","age":25},{"name":"Jane","age":30}]';
List<ObjectModel> objects = parseObjects(json);
