json2yaml #
Dart package to render JSON data to YAML:

Correct handling of nested structures
Built-in automatic beautifer
Supports Dart pubspec.yaml conventions
Compatible with conventions imposed by Dart pubspec.lock generator

Known limitations #

Strings (single line and multiline) are always formatted as they are,
without word wrapping for better human readability

const developerData = {
'name': "Martin D'vloper",

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) -- Default formatting style applicable in most cases
YamlStyle.pubspecYaml -- YAML formatting style following pubspec.yaml formatting conventions
YamlStyle.pubspecLock -- YAML formatting style following pubspec.lock formatting conventions

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,
});
