Integration Guide

Follow these steps to integrate quick_payment into your Flutter app:

1️⃣ Import the package

import 'package:quick_payment/quick_payment.dart';

2️⃣ Prepare Customer Details

Use CustomerDetails to provide customer name and email.
This will be included in PaymentData for your DB storage.

final customer = CustomerDetails(
  fullName: 'Khalid LikhOn',
  email: '[e-mail]',
);

3️⃣ Setup Payment Credentials

Use QuickPayCredentials to configure mobile banking numbers and optional fee percentage.

final credentials = QuickPayCredentials(
  feePercentage: 1.8, // optional
  methods: [
    PaymentMethod.bkash("016xxxxxxxx"),
    PaymentMethod.nagad("017xxxxxxxx"),
    PaymentMethod.rocket("018xxxxxxxx"),
    // PaymentMethod.upay("019xxxxxxxx"), // optional
  ],
);

Replace the numbers with your personal mobile banking numbers to receive payments.

4️⃣ Trigger Payment Flow

Call QuickPay.createPayment() on button press or action.

QuickPay.createPayment(
  context: context,
  amount: 200, // Payment amount
  customer: customer,
  credentials: credentials,
  onPaymentSubmitted: (data) {
    // PaymentData returned after user submits
    // Save to your database manually
    print(data.toMap());
  },
);

onPaymentSubmitted returns a PaymentData object with:

Field	Description
customer	CustomerDetails object (name & email)
amount	Payment amount
method	Payment method type (e.g., bKash)
transactionId	User-entered transaction ID
time	DateTime when payment submitted
status	Default "pending" – approve manually in DB

⚠️ Payment status is "pending" by default. You must manually verify and approve in your system.

Usage Example

This example demonstrates how to use QuickPayment with multiple payment methods in your Flutter app. Clicking the Pay Now button opens the payment dialog and handles submission callbacks.

import 'package:flutter/material.dart';
import 'package:quick_payment/quick_payment.dart';

void main() {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: const HomePage(),
      debugShowCheckedModeBanner: false,
    );
  }
}

class HomePage extends StatelessWidget {
  const HomePage({super.key});

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(title: const Text("Quick Payment Example")),
      body: Center(
        child: ElevatedButton(
          onPressed: () {
            // Customer Details
            final customer = CustomerDetails(
              fullName: 'Khalid LikhOn',
              email: '[e-mail]',
            );

            // Payment Credentials & Methods
            final credentials = QuickPayCredentials(
              feePercentage: 1.8,
              methods: [
                PaymentMethod.bkash("016xxxxxxxx"),
                PaymentMethod.nagad("017xxxxxxxx"),
                PaymentMethod.rocket("018xxxxxxxx"),
                // PaymentMethod.upay("019xxxxxxxx"), // optional
              ],
            );

            // Trigger Payment Flow
            QuickPay.createPayment(
              context: context,
              amount: 200,
              customer: customer,
              credentials: credentials,
              onPaymentSubmitted: (data) {
                // Returned PaymentData
                print(data.toMap());
                // Save to DB manually, status = "pending"
              },
            );
          },
          child: const Text("Pay Now"),
        ),
      ),
    );
  }
}
