virak

virak is a Flutter package that provides utilities and widgets for easy CRUD operations with REST APIs.
It is designed to simplify API integration, handle tokens automatically, and work with user-defined models and endpoints with CRUD Laravel.

---

Advantages of This Package

• Works for both public and secured APIs: Handles endpoints that require authentication or are open.
• Optional token support: Tokens are only used if set, allowing flexible API usage.
• Automatic token handling for CRUD requests: Tokens are automatically included in all create, read, update, and delete requests.
• Flexible user-defined models and endpoints: Easily adapt to any project by passing custom data models and API endpoints.

---

Getting Started

Add virak to your pubspec.yaml:

dependencies:
  virak: ^0.0.1

Run:

flutter pub get

---

Setup

Before making requests, configure the base URL and optionally set an authentication token.

import 'package:virak/virak.dart';

void main() {
  setBaseUrl("https://api.example.com");
  setAuthToken("your_token_here");
}

---

Usage

GET request (no model)

void fetchItems() async {
  try {
    final items = await getData<List<dynamic>>(endpoint: "items");
    print(items);
  } catch (e) {
    print("Error: $e");
  }
}

---

GET request with model mapping

class User {
  final int id;
  final String name;

  User({required this.id, required this.name});

  factory User.fromJson(Map<String, dynamic> json) {
    return User(
      id: json["id"],
      name: json["name"],
    );
  }
}

void fetchUser() async {
  try {
    final user = await getData<User>(
      endpoint: "users/1",
      fromJson: (json) => User.fromJson(json),
    );
    print("User: ${user.name}");
  } catch (e) {
    print("Error: $e");
  }
}

---

POST request

void createUser() async {
  try {
    final result = await postData<Map<String, dynamic>>(
      endpoint: "users",
      body: {"name": "John Doe", "email": "[e-mail]"},
    );
    print(result);
  } catch (e) {
    print("Error: $e");
  }
}

---

PUT request

void updateUser() async {
  try {
    final result = await putData<Map<String, dynamic>>(
      endpoint: "users/1",
      body: {"name": "Jane Doe"},
    );
    print(result);
  } catch (e) {
    print("Error: $e");
  }
}

---

DELETE request

void deleteUser() async {
  try {
    await deleteData(endpoint: "users/1");
    print("User deleted");
  } catch (e) {
    print("Error: $e");
  }
}

Notes

• You must call setBaseUrl() before making any request.
• Tokens are optional — if not set, requests are sent without authentication.
• Use fromJson to convert API responses into your own model classes.
