JSON to Dart #

This Dart package, json_to_dart_class, facilitates the generation of Dart class files from JSON data. It provides a convenient way to convert JSON structures into corresponding Dart classes, making it easier to work with JSON data in Dart applications.

Installation #

To use json_to_dart_class in your Dart project, add it to your pubspec.yaml file:

dependencies:
  json_to_dart_class: ^1.0.0

Then, run flutter pub get to install the package.

Usage #

The package offers two main ways to generate Dart classes:

1. Simple Usage:

This approach is ideal for basic JSON structures. Below is an example demonstrating how to use it:

import 'package:json_to_dart_class/json_to_dart_class.dart';

void main() {
  // Define your JSON data
  Map<dynamic, dynamic> json = {
    'name': 'John Doe',
    'age': 30,
    'isStudent': false,
    'address': {
      'city': 'New York',
      'zip': '10001'
    },
    'hobbies': ['Reading', 'Traveling']
  };

  // Specify class name and folder path for generated files
  String className = 'Person';
  String folderPath = 'lib/models';

  // Generate Dart class file
  jsonToDart(
    json: json,
    className: className,
    folderPath: folderPath,
  );
}

This will generate a Dart class file named person.dart inside the specified folder (lib/models) with the corresponding Dart class for the provided JSON structure.

2. Advanced Usage with Options:

This approach provides more control over the generated code. Here's an example demonstrating advanced usage:

import 'package:json_to_dart_class/json_to_dart_class.dart';

void main() async {
  var json = {
    "status": "success", 
    "age": 32, 
    "feed": {
      "len": 10, 
      "wd": "Sunny", 
      "speed": 25.0, 
      "location": {
        "address": "123 Main Street", 
        "postal_code": "12345",
        "city": "Miami", 
      },
      "childs": [
        {
          "name": "Emily", 
          "age": 8 
        },
        {
          "name": "David", 
          "age": 5 
        },
        {
          "name": "Sarah", 
          "age": 12 
        }
      ]
    }
  };

  await jsonToDart(
    json: json,
    className: 'WeatherData', // Class name for the main structure
    library: 'weather',      // Library name for generated code
    folderPath: 'src/weather', // Folder path for generated files
  );
}

This will generate multiple class files:

  • weather_data.dart containing the WeatherData class for the main structure.
  • Nested classes for objects within the feed object (e.g., Location, Child).

Features #

  • Generates Dart class files from JSON data
  • Supports nested JSON structures
  • Handles different data types (String, int, double, bool, List, Map)
  • Offers options for advanced usage (library name, folder path)
