  const developerData = {

    'employed': true,
    'foods': ['Apple', 'Orange', 'Strawberry', 'Mango'],

This function is implemented in a very basic and perhaps naive way, please let me know if it does not work for you.

Usage #

To use json2yaml, add the following dependency to pubspec.yaml:

  json2yaml: ^1.0.0

Advanced usage: YAML formatting styles #

json2yaml supports the optional argument to customize YAML formatting for various use cases. At the moment, it supports the three following formatting styles:

  • YamlStyle.generic (default) -- generic Yaml rendering
  • YamlStyle.pubspecYaml -- Yaml formatting style mimicking pubspec.yaml files
  • YamlStyle.pubspecLock -- Yaml formatting style mimicking pubspec.lock files generated by Dart pub

YAML style is supplied as an optional argument to json2yaml():

/// Yaml formatting control options
enum YamlStyle {

/// Converts JSON to YAML representation
String json2yaml(
  Map<String, dynamic> json, {
  YamlStyle yamlStyle = YamlStyle.generic,
