arxing / dart-xson

Xson is a pure library for resolving json, bean generating will move to xson_builder.

Usage

Xson used like Gson.

Json member

class	mirror type
JsonElement	any
JsonNull	null
JsonPrimitive	int, double, bool and String
JsonObject	Map
JsonArray	List

other

class	description
JsonSerializer	json serialize
JsonDeserializer	json deserialize
JsonFormatter	format json string
JsonInfo	resolve json structure to md5
JsonType	enum of json type

A simple usage example:

import 'package:xson/xson.dart';

var jsonString1 = """
{"aa":100, "b":[1,2,3], "c":{"c1":[666]}}
""";

var json1 = {
  "aa": 100,
  "b": [1, 2, 3],
  "c": {
    "c1": [666]
  }
};

void main() {
  // string to json element

  // way1
  JsonElement element1 = xson.decodeToJsonElement(jsonString1);
  // way2
  JsonElement element2 = JsonElement.fromJsonString(jsonString1);
  // way3
  JsonElement element3 = JsonElement.fromJson(json1);

  // element to other type
  JsonObject object = element1.asObject; // {"aa": 100, "b": [1, 2, 3], "c": {"c1": [666]}};
  JsonArray array = object["b"].asArray; // [1,2,3]
  array[0].asInt; // 1

  // element to string
  print(element1.toString());
  print(element1.toJsonString(prettify: true, indent: 4));
  print(xson.encodeFromJsonElement(element1, prettify: true));

  // element to json dynamic
  element1.toJson();

  // traversal all nodes of element
  JsonSerializeCallback callback = (JsonElement node, dynamic parent, int depth) {
    // do something
  };
  element1.traversalChildrenNode(callback);
}
