JSON5 for Dart and Flutter

Dart CI

This Dart package is a port of JSON5, originally written in pure JavaScript.

It follows the same algorithms and specifications as the original JSON5, ensuring identical behavior.

However, Dart has different naming conventions—see the example below.

Usage

import 'package:json5/json5.dart';

void main() {
  var obj = JSON5.parse('''
      {  
        /* Comment block */  
        name: { first: "Phat" },  
        lang: ["C++", "Dart", "Kotlin"],  
        nums: [NaN, Infinity, -Infinity]  
      } // End object
  ''');

  var compact = JSON5.stringify(obj);
  print(compact);

  var pretty = JSON5.stringify(obj, space: 2);
  print(pretty);
}
