gg_json 3.0.7

gg_json offers a bunch of JSON helpers used in various context.

gg_json

gg_json offers small, composable helpers for working with JSON-like Map<String, dynamic> structures in Dart. It focuses on utility functions that make it easier to copy, inspect, and share JSON payloads across tests, tooling, and Flutter/Dart applications.

Features

• Deep-copy JSON maps and lists while preserving nested structure.
• Access a curated exampleJson payload for demos, tests, or docs.
• Lightweight: no hidden dependencies beyond the Dart SDK.

Install

Add the package to your project:

dart pub add gg_json

Import the helpers where you need them:

import 'package:gg_json/gg_json.dart';

Usage

Deep copy a JSON map

import 'package:gg_json/gg_json.dart';

void main() {
  final data = {
    'user': {'name': 'Ada', 'skills': ['math', 'logic']},
    'active': true,
  };

  final clone = deepCopy(data);
  clone['user']?['skills']?.add('computing');

  // Original data remains untouched.
  print(data['user']?['skills']); // [math, logic]
  print(clone['user']?['skills']); // [math, logic, computing]
}
