Convert to type class dart http response body

I just want to convert the response.body to class file named as Collection.

The response from http.post on flutter would result the below code from server

{"collection":{
   "data": "{\"id\": 1, 
           \"name\": \"Puspharaj\",
           \"picture\": \"https://lh3.googleusercontent.com/a-/AAuE7mC1vqaKk_Eylt- 
           fcKgJxuN96yQ72dBViK959TKsHQ=s96-c\"}",
   "statusCode": 202,
   "version": "1.0"}
}

The collection file in flutter has this code:

import 'dart:core';

class Collection {
var version = String;
/**
 * @return the data
 */
/**
 * @param data the data to set
 */
 var data = dynamic;
/**
 * @return the error
 */
/**
 * @param error the error to set
 */
var error = String;
var statusCode = int;
var isBooleanStatus = bool;
}

When i tried to convert it says

A value of type 'String' can't be assigned to a variable of type 'Type'. Try changing the type of the variable, or casting the right-hand type to 'Type'

So the end result should be like this:

Collection{
version : 1.0
data : "{\"id\": 1, 
           \"name\": \"Puspharaj\",
           \"picture\": \"https://lh3.googleusercontent.com/a-/AAuE7mC1vqaKk_Eylt- 
           fcKgJxuN96yQ72dBViK959TKsHQ=s96-c\"}"
statusCode : 202
}

So i can extract the only data i wanted. Like data only or the statuscode . So how do convert the response body code to the flutter code?. Please any help appreciated.

if your data is with known columns, you should create another class for itself like below; else Darish's answer is more appropriate

class Collection {
  Data data;
  String statusCode;
  String version;

  Collection(this.data, this.statusCode, this.version);
}

class Data {
  String id;
  String name;
  String picture;

  Data(this.id, this.name, this.picture);
}

Try this

class Collection {
String version;
/**
 * @return the data
 */
/**
 * @param data the data to set
 */
 Map<String, dynamic> data;
/**
 * @return the error
 */
/**
 * @param error the error to set
 */
String error;
int statusCode;
bool isBooleanStatus;
}
