json2yaml

Dart package to render JSON data to YAML

json2yaml()

json2yaml is the function to format JSON data to YAML.

  const developerData = {
    'name': "Martin D'vloper",
    'job': 'Developer',
    'skill': 'Elite',
    'employed': true,
    'foods': ['Apple', 'Orange', 'Strawberry', 'Mango'],
    'languages': {
      'perl': 'Elite',
      'python': 'Elite',
      'pascal': 'Lame',
    },
    'education': '4 GCSEs\n3 A-Levels\nBSc in the Internet of Things'
  };

  print(json2yaml(developerData));

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

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 {
  generic,
  pubspecYaml,
  pubspecLock,
}

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