flutter_channel_json

用来规范 Method Channel 数据传输的数据格式,通常结合 flutter_channel_event_bus 使用。

添加依赖

flutter pub add flutter_channel_json

怎么使用

Dart

import 'package:flutter_channel_json/flutter_channel_json.dart';

默认初始化

const json = FlutterChannelJson(
  code: 300,
  message: 'message',
  success: false,
  data: 2,
);

根据字典初始化

final json = FlutterChannelJson.fromJson({
  'code': 300,
  'message': 'message',
  'data': 2,
  'success': false,
});

根据 JSON 字符串初始化

final json = FlutterChannelJson.fromJsonString(
  '{"code": 300, "message": "message", "data": 2, "success": false}',
);

将对象转换为字典

final json = const FlutterChannelJson(
  code: 300,
  message: 'message',
  success: false,
  data: 2,
).toJson();

将对象转换为字符串

final json = const FlutterChannelJson(
  code: 300,
  message: 'message',
  success: false,
  data: 2,
).toJsonString();

初始化成功类型

final json = FlutterChannelJson.success(2);

初始化失败类型

final json = FlutterChannelJson.failure('message');

Swift

默认初始化

let json = FlutterChannelJson(code: 300,
                              message: "message",
                              data: 2,
                              success: false)

初始化成功类型

let json = FlutterChannelJson(success: 2)

初始化失败类型

let json = FlutterChannelJson(failure: "message", code: 300)

根据字典初始化

let json = FlutterChannelJson<Int>(json: ["code": 300,
                                          "message": "message",
                                          "data": 2,
                                          "success": false])

根据 JSON 字符串初始化

let json = try? FlutterChannelJson<Int>(jsonString: "{\"code\":300,\"message\":\"message\",\"data\":2,\"success\":false}")

对象转化为 JSON 字符串

let json = FlutterChannelJson(code: 300,
                              message: "message",
                              data: 2,
                              success: false)
let jsonString = json.toJsonString()

对象转换为字典

let json = FlutterChannelJson(code: 300,
                              message: "message",
                              data: 2,
                              success: false)
let jsonMap = json.toJson()

Kotlin

默认初始化

val json = FlutterChannelJson(code = 300, message = "message", data = 2, success = false)

初始化成功类型

val json = FlutterChannelJson(data = 2)

初始化失败类型

val  json = FlutterChannelJson<Int>(message = "message")

根据 JSON 字符串初始化

val json = FlutterChannelJson(jsonString = "{\"code\":300,\"message\":\"message\",\"data\":2,\"success\":false}", Int::class.java)

根据字典初始化

val map: Map<String,Any> = mapOf("code" to 300, "message" to "message", "data" to 2, "success" to false)
val json = FlutterChannelJson<Int>(json = map)

对象转化为 JSON 字符串

val json = FlutterChannelJson(code = 300, message = "message", data = 2, success = false).toJsonString()

对象转换为字典

val json = FlutterChannelJson(code = 300, message = "message", data = 2, success = false)
val map = json.toJson()
