Convert data menjadi class model dart dengan online generator

Gunakan converter berikut untuk membuat class:

https://app.quicktype.io/

Buatlah class berdasarkan hasil converter tersebut, misal user.dart

	class User {
	int id;
	String name;
	String email;
	String devilFruit;
	String gender;
	String role;
	int level;
	String createAt;
	String updatedAt;
	User(
	{this.id,
	this.name,
	this.email,
	this.devilFruit,
	this.gender,
	this.role,
	this.level,
	this.createAt,
	this.updatedAt});
	User.fromJson(Map<String, dynamic> json) {
	id = json['id'];
	name = json['name'];
	email = json['email'];
	devilFruit = json['devil_fruit'];
	gender = json['gender'];
	role = json['role'];
	level = json['level'];
	createAt = json['create_at'];
	updatedAt = json['updated_at'];
	}
	Map<String, dynamic> toJson() {
	final Map<String, dynamic> data = new Map<String, dynamic>();
	data['id'] = this.id;
	data['name'] = this.name;
	data['email'] = this.email;
	data['devil_fruit'] = this.devilFruit;
	data['gender'] = this.gender;
	data['role'] = this.role;
	data['level'] = this.level;
	data['create_at'] = this.createAt;
	data['updated_at'] = this.updatedAt;
	return data;
	}
