to ts

export interface BaseResponse {
  code: number;
  bigInt: number;
  doubleValue: number;
  message: any; // ⚠️⚠️⚠️ null value
  : string; // ⚠️⚠️⚠️ empty name
  auth: boolean;
  pageInfo: PageInfo;
  enum: string[];
  data: Data[];
}

export interface PageInfo {
  pageNum: number;
  pageSize: number;
}

export interface Data {
  id: string;
  title: string;
  price: number;
  hasBuy: boolean;
  studentNum: number;
}

to dart

众所周知flutter中无法使用反射，需搭配 JSON and serialization 使用

@JsonSerializable()
class BaseResponse {
  number: code;
  Int64: bigInt;
  double: doubleValue;
  Null: message; // ⚠️⚠️⚠️ null value
  String: ; // ⚠️⚠️⚠️ empty name
  bool: auth;
  PageInfo: pageInfo;
  undefined: enum;
  undefined: data;
  BaseResponse({ this.code, this.bigInt, this.doubleValue, this.message, this., this.auth, this.pageInfo, this.enum, this.data });

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

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

@JsonSerializable()
class PageInfo {
  number: pageNum;
  number: pageSize;
  PageInfo({ this.pageNum, this.pageSize });

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

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

@JsonSerializable()
class Data {
  String: id;
  String: title;
  number: price;
  bool: hasBuy;
  number: studentNum;
  Data({ this.id, this.title, this.price, this.hasBuy, this.studentNum });

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

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

proto to dart/js

installation

• 将废弃j2a，扩展为a2a

$ yarn global add @j2a/cli # or npm i -g @j2a/cli

usage

$ j2a -i path/to/json -o path/to/dist -t typescript # convert json to any

$ j2a --help
Usage: j2a [options]

convert path/to/*.json to path/to/*.any

Options:
  -V, --version        output the version number
  -i, --input <path>   json source directory path
  -o, --output <path>  export directory path
  -t, --type <type>    typescript dart (default: "typescript")
  -w, --watch          watch mode
  -h, --help           display help for command
