VS Code Plugin: J2O - Json to Dart (freezed)

This VS Code plugin simplifies the process of converting JSON data into Dart class models. It offers a variety of options to customize the generated code to suit your project's needs, including:

1.Null Safety: Ensures that your Dart classes are null-safe, making them more robust and compatible with modern Dart standards.
2.Data Type Checking: Automatically checks and assigns appropriate data types for each property.
3.Freezed Annotations: Supports Freezed package annotations for immutable classes, making it easy to generate data classes.
4.FromJson Method: Generates a fromJson method for easy deserialization of JSON data.
5.ToJson Method: Includes a toJson method to serialize Dart objects back into JSON.
6.CopyWith Function: Provides a copyWith function to create modified copies of objects with ease.
7.Optional Properties: Allows properties to be marked as optional, providing flexibility in handling incomplete data.

This plugin is a valuable tool for Flutter and Dart developers looking to streamline their workflow when working with JSON data, saving time and reducing errors.
