flutter-implement-json-serialization

Create model classes with `fromJson` and `toJson` methods using `dart:convert`

flutter-implement-json-serialization is an agent skill for writing JSON serialization by hand in Flutter, using the built-in dart:convert library. It is meant for simple data models where you map JSON keys to class properties yourself, rather than generating code. The skill's guidelines say to call jsonEncode and jsonDecode from dart:convert, to cast the result of jsonDecode to Map<String, dynamic> for objects or List<dynamic> for arrays, and to put each model in a plain class with a fromJson factory constructor and a toJson method. For large documents that take more than about 16 milliseconds to parse, it advises running the parsing in an isolate with compute() so the UI does not stall. When an HTTP response has an unsuccessful status code, the skill says to throw an exception rather than return null. A workflow walks the agent through implementing a serializable model and then through fetching and parsing JSON from a network call. Examples are included. The skill is part of Flutter's agent-plugins repository, and it is installed with the skills command in a compatible agent such as Claude Code. It is useful for Flutter developers who prefer hand-written models to generated ones.
