jio_payment_sdk #

A custom Flutter payment SDK that allows developers to easily integrate their own backend-based payment flow using Dio and Firebase or any backend system.

🔧 Features #

• 🚀 Easy payment order creation
• 🔐 Backend integration with secure verification
• 🔁 Dio-powered async HTTP communication
• 📁 Fully customizable for any payment gateway
• 🔎 Firebase-ready (compatible with Firestore)

📦 Installation #

Add this to your pubspec.yaml:

dependencies:
  jio_payment_sdk: ^1.0.0 

Then run:

flutter pub get

✅ Prerequisites #

Your backend must support:

createOrder endpoint — returns a unique orderId

verifyPayment endpoint — receives orderId + success flag

We recommend Firebase Functions, Node.js, or Express.

💻 Usage #

import 'package:jio_payment_sdk/jio_payment_sdk.dart';

final service = PaymentService(
  createOrderUrl: 'https://your-backend.cloudfunctions.net/createOrder',
  verifyPaymentUrl: 'https://your-backend.cloudfunctions.net/verifyPayment',
);

final orderId = await service.createOrder(
  amount: 499,
  userId: 'abc123',
);

await service.verifyPayment(
  orderId: orderId,
  success: true,
);
