JSON to Dart json_serializable Converter

How to use

1. Paste a JSON payload that reflects the DTO shape your app exchanges with APIs or local caches.
2. Review the generated Dart classes, @JsonSerializable annotations, and fromJson/toJson helpers.
3. Copy the code into your project and run build_runner to generate the serializer part files.

Benefits

• Produces DTO output tailored for json_serializable annotation-based code generation.
• Keeps generated models lighter than a full Freezed-based setup.
• Works well for teams that want explicit classes plus generated serializers.

Best use cases

• Flutter apps that already use build_runner and json_serializable for DTO code generation.
• Shared Dart model layers where explicit classes are preferred over immutable unions.
• Teams that want generated serializer helpers without adopting Freezed-specific patterns.

json_serializable tips

• Keep generated DTO files near the API or repository layer where serialization actually happens.
• Review nullable fields and collection defaults before running build_runner in a real app.
• Use the plain Dart route instead when you want to avoid annotation-driven code generation.

Sample JSON

{
  "id": 101,
  "name": "Ada Lovelace",
  "active": true,
  "roles": ["admin", "editor"],
  "profile": {
    "email": "ada@example.com",
    "score": 9.8
  }
}
