🚀 Installation

To install from pub.flutter-io.cn, run:

dart pub add json_model_gen Or manually add it to your pubspec.yaml:

dependencies: json_model_gen: ^0.0.6 Then run:

dart pub get

🔧 Usage

📦 Full command with flags: dart run json_model_gen
--input=raw.json
--output=lib/user_model.dart
--class=UserModel
--freezed
--equatable
--nullable

🧠 Or use interactive mode: Just run:

dart run json_model_gen It will ask you step-by-step:

📥 Input file path 📤 Output file path 🧪 Class name ⚙️ Use equatable ❄️ Use freezed ❓ Make all fields nullable 📌 Example

Input (raw.json) { "id": 1, "name": "Alice", "active": true, "bio": null } Output (user_model.dart) import 'package:freezed_annotation/freezed_annotation.dart';

part 'user_model.freezed.dart'; part 'user_model.g.dart';

@freezed class UserModel with _$UserModel { const factory UserModel({ int? id, String? name, bool? active, String? bio, }) = _UserModel;

factory UserModel.fromJson(Map<String, dynamic> json) => _$UserModelFromJson(json); }

⚠️ Notes

✅ Input file must contain ONLY valid JSON, not Dart code. 📄 If your input file ends with .dart, it will still work, but a warning will appear. 🧪 Class names are validated to be in PascalCase. 📌 --output=model.json will auto-convert to model.dart.
