  "message": "Replace `json_utils` with a modern `extension type`, add tests. (#52769)\n\nI started on a refactoring of\nhttps://github.com/flutter/flutter/issues/147666, and was frustrated\nwith the JSON decoding of `gn desc --format\u003djson`, so I used a similar\npattern from my micro-json library (https://pub.dev/packages/jsonut) and\nencapsulated it as an extension type.\n\nMy favorite is the `JsonObject.map` function which replaces:\n\n```dart\n/// Construct a RunTarget from a JSON map.\nfactory RunTarget.fromJson(Map\u003cString, Object\u003e map) {\n  final List\u003cString\u003e errors \u003d \u003cString\u003e[];\n  final String name \u003d stringOfJson(map, _nameKey, errors)!;\n  final String id \u003d stringOfJson(map, _idKey, errors)!;\n  final String targetPlatform \u003d\n      stringOfJson(map, _targetPlatformKey, errors)!;\n\n  if (errors.isNotEmpty) {\n    throw FormatException(\u0027Failed to parse RunTarget: ${errors.join(\u0027\\n\u0027)}\u0027);\n  }\n  return RunTarget._(name, id, targetPlatform);\n}\n```\n\n... with:\n\n```dart\n/// Construct a RunTarget from a JSON map.\nfactory RunTarget.fromJson(Map\u003cString, Object\u003e map) {\n  return JsonObject(map).map((JsonObject json) \u003d\u003e RunTarget._(\n    json.string(_nameKey),\n    json.string(_idKey),\n    json.string(_targetPlatformKey),\n  ));\n}\n```",
