从 Flutter 文件中的 json 文件自动生成 class 和成员

Question

I have a simple json file like below. This is fixed in the project.

{
    "en": "English",
    "es": "Español",
    "fr": "Français"
}

My question is, is it possible to do a auto-generate work to create a class with members which return the value of each key? The result of the auto-generate can be similar to below example. So every time I add new key and value to the json file, this class will generate or update that new item into it.

class JsonHelper {
    static String get en => json['en'];

    static String get es => json['es'];

    static String get fr => json['fr'];
}

another way is using Auto-generator package of npm

Answer 2

Yes for sure you can use Auto-generate class in Flutter on this website: Instantly parse Json

Example

 // To parse this JSON data, do // // final autoGenerate = autoGenerateFromJson(jsonString); import 'dart:convert'; AutoGenerate autoGenerateFromJson(String str) => AutoGenerate.fromJson(json.decode(str)); String autoGenerateToJson(AutoGenerate data) => json.encode(data.toJson()); class AutoGenerate { AutoGenerate({ this.en, this.es, this.fr, }); String en; String es; String fr; factory AutoGenerate.fromJson(Map<String, dynamic> json) => AutoGenerate( en: json["en"], es: json["es"], fr: json["fr"], ); Map<String, dynamic> toJson() => { "en": en, "es": es, "fr": fr, }; }

you can then simply use final objectFromClass = autoGenerateFromJson(jsonString)
