RocketCLI

Rocket CLI

rocket_cli is a command-line tool designed to eliminate the boilerplate of creating RocketModel classes. It converts any JSON (from a string or a file) into fully optimized Dart code.

Installation

Activate the CLI globally using Dart:

dart pub global activate rocket_cli

Usage

You can generate a model from a JSON string:

rocket_cli -j '{"id": 1, "name": "John"}' -n User

Or from a JSON file:

rocket_cli -f data.json -n Result

Features

• Automatic Serialization: Generates fromJson and toJson methods.
• Field Constants: Automatically creates const strings for field keys to prevent typos.
• Performance Optimized: Generates updateFields logic with built-in support for Selective Rebuilds.
• Nested Detection: Automatically detects nested objects and lists, generating appropriate sub-models.
• DateTime Support: Automatically detects and handles ISO8601 date strings.

Generated Model Structure

When you run the tool, it creates a Dart file containing:

1. Constants: const String userIdField = "id";
2. Model Class: class User extends RocketModel<User> { ... }
3. Methods:
   • fromJson: To parse API data.
   • toJson: To send data back.
   • updateFields: Optimized for high-performance state updates.

Why use it?

Manually writing model serialization is error-prone and tedious. rocket_cli ensures your models are consistent, follow best practices, and are optimized for the latest features of Flutter Rocket.
