json_serializable_lints

Focused static analysis rules for projects that use json_serializable.

json_serializable is an excellent library for JSON serialization and deserialization in Dart. However, with current Dart capabilities, each serializable model still needs a small amount of boilerplate — most commonly a fromJson factory and a toJson method.

Those members are easy to forget when creating or refactoring models. This package helps catch those mistakes early with static analysis, so your @JsonSerializable() classes stay consistent and ready for code generation.

What this package checks

• require_json_serializable_from_json
  Requires factory ClassName.fromJson(Map<String, dynamic> json) on @JsonSerializable() classes.
• require_json_serializable_to_json
  Requires Map<String, dynamic> toJson() on @JsonSerializable() classes.

If you intentionally disable generation with createFactory: false or createToJson: false, the corresponding rule is skipped.

Usage

Add the plugin to your Dart or Flutter project:

# analysis_options.yaml
plugins:
  json_serializable_lints: any

Your IDE will usually run analysis automatically and show these warnings inline as you work. You can also run analysis manually:

dart analyze

See the repository examples for ignore patterns and more details.
