🎯 Dart Data Class Generator

Create Dart data classes quickly without writing boilerplate or running code generation.

✨ Features

Generate complete data classes with:

✅ Constructor with optional default values and smart const inference
✅ copyWith method for immutable updates
✅ toString method for debugging
✅ toJson/fromJson methods for serialization
✅ operator== and hashCode for value equality
✅ Equatable integration support
✅ Final class keyword support (Dart 3.0+)
✅ Empty factory constructor for form initialization
✅ Example list generator with sample data

🚀 Getting Started

📝 Generate from Class Properties

Class properties demo

⚡ Quick Fix (Single Class)

📄 Create a class with properties
🎯 Place cursor on class name, constructor, or field
⌨️ Press Ctrl + . (or Cmd + . on macOS)
✨ Select desired generation option

🔧 Command (Multiple Classes)

⌨️ Press Ctrl + P (or Cmd + P on macOS)
🔍 Search for "Dart Data Class Generator: Generate from class properties"
✅ Select classes to generate when prompted

💡 Tip: You can run the generator on existing data classes to update them after property changes.

🔄 Generate from JSON

JSON demo

📄 Create an empty Dart file
📋 Paste raw JSON into the file
⌨️ Press Ctrl + P (or Cmd + P on macOS)
🔍 Search for "Dart Data Class Generator: Generate from JSON"
✏️ Enter name for the root class
📂 Choose whether to separate nested classes into multiple files

📋 Generate from Clipboard (New!)

📋 Copy JSON to your clipboard
📄 Open a Dart file
⌨️ Press Ctrl + P (or Cmd + P on macOS)
🔍 Search for "Dart Data Class Generator: Generate from Clipboard"
✏️ Enter name for the root class

✨ Smart Features:

Date Detection: ISO 8601 date strings are automatically converted to DateTime

Array Type Inference: Mixed arrays like [1, 2, 3.5] correctly infer double

🏷️ Working with Enums

To ensure enums are correctly serialized, annotate them:

// enum
final Enum myEnum;

🎁 Additional Features

The extension includes some additional quick fixes that might be useful to you:

📦 Import Refactoring

Sort imports alphabetically and bring them into the correct format easily.
