Flutter: JSON to Dart Class in One Click

Flutter becomes more and more popular. The plugin I m about to talk about is the same, saving time by converting the JSON file to a Dart class for you. The JSON to Dart plugin helps us achieve exactly that. JSON stands for JavaScript Object Notation, It is a lightweight format used for storing and transporting the data, it is used when you make a call to server and it has to return some data, which the server returns in the form of JSON.

As Flutter becomes more and more popular, people keep coming with amazing ideas to make hard stuff easier and easier. The plugin I m about to talk about is the same, saving time by converting the JSON file to a dart class for you, so you can focus more on the logic building side of things.

The JSON to Dart plugin helps us achieve exactly that, Its a wonderful plugin with many build in features to make the life of developer easier.

Now, before we dive into installing and using the plugin, let us first discuss what exactly is JSON?

JSON stands for JavaScript Object Notation, It is a lightweight format used for storing and transporting the data, it is used when you make a call to server and it has to return some data, which the server returns in the form of JSON.

An example of JSON is :

{
  "names" : [
    {
      "first_name" : "Joe",
      "middle_name" : "Rio",
      "last_name" : "Morn"
    },
    {
      "first_name" : "Joe",
      "middle_name" : "Rio",
      "last_name" : "Morn"
    },
    {
      "first_name" : "Joe",
      "middle_name" : "Rio",
      "last_name" : "Morn"
    }
  ]
}

The main rules of creating a JSON is that you must use double quotes (“ “) and every values must be a pair of name and value, the name is the field name which is on the left side and on its right side is its corresponding value.

In the example, the names is a List which contains a Map of names of employee which have following fields

  1. first_name
  2. middle_name
  3. last_name

To gather more information on JSON you can look up W3Schools.

Now we move onto getting the plugin itself, To install all you need to do is go to
