可以在flutter中从json body打印多个属性吗？

{
  "name": "John",
  "age": 25,
  "email": "john@example.com"
}

import 'package:json_annotation/json_annotation.dart';

part 'user.g.dart';

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

  User({required this.name, required this.age, required this.email});

  factory User.fromJson(Map<String, dynamic> json) => _$UserFromJson(json);
  Map<String, dynamic> toJson() => _$UserToJson(this);
}

flutter pub run build_runner build

import 'dart:convert';

import 'package:flutter/material.dart';

class MyWidget extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    final jsonString = '{"name": "John", "age": 25, "email": "john@example.com"}';
    final jsonMap = json.decode(jsonString);
    final user = User.fromJson(jsonMap);

    print('Name: ${user.name}');
    print('Age: ${user.age}');
    print('Email: ${user.email}');

    return Container();
  }
}
