What is JSON?

JSON, or JavaScript Object Notation, is a lightweight data format used for storing and transferring data. In mobile applications, it is widely used when communicating with backend services and APIs.

• Paste your JSON data into the input field
• Click on “Generate Dart Code”
• Copy the generated model
• Use it in your Flutter project

{
  "name": "John",
  "age": 25,
  "isActive": true
}

• Saves time during development
• Reduces manual errors
• Easy to use for beginners
