json_model_gen is a Dart code generator that automatically creates model classes from JSON input, including essential methods like fromJson, toJson, copyWith, and equality overrides. It streamlines data serialization and deserialization in Flutter apps by reducing boilerplate code. The tool integrates seamlessly with the Flutter ecosystem and supports multiple platforms, making it ideal for projects relying heavily on JSON APIs. Generated models are type-safe and maintainable, improving development speed and code quality.
