UPI Payment Flutter Package

The upi_payment_flutter package is a Flutter plugin that simplifies the process of integrating UPI-based payment services into your app. It supports initiating transactions through UPI-enabled applications installed on the user's device.

Features

• Initiate UPI transactions by generating and launching UPI URLs
• Handle errors when UPI payment is not supported on the user's device

Installation

To use this package, add it as a dependency in your pubspec.yaml file:

dependencies:
  upi_payment_flutter: ^0.0.1

Then, run flutter pub get to download and install the package.

Usage

To use the upi_payment_flutter package, follow these steps:

1. Import the package:

import 'package:upi_payment_flutter/upi_payment_flutter.dart';

2. Create an instance of the UpiPaymentHandler class:

final upiPaymentHandler = UpiPaymentHandler();

3. Initiate a UPI transaction:

void _initiateTransaction() async {
  try {
    bool success = await upiPaymentHandler.initiateTransaction(
      payeeVpa: 'example@upi',
      payeeName: 'Example Merchant',
      transactionRefId: 'TXN123456',
      transactionNote: 'Test transaction',
      amount: 10.0,
    );

    if (success) {
      // Handle successful transaction initiation
    } else {
      // Handle unsuccessful transaction initiation
    }
  } on PlatformException catch (e) {
    // Handle errors when UPI is not supported on the user's device
  }
}

Replace the parameter values with the appropriate details for your transaction.

Error Handling

The initiateTransaction method may throw a PlatformException if UPI payments are not supported on the user's device. You should catch this exception and handle it accordingly in your app.

try {
  // initiate transaction
} on PlatformException catch (e) {
  // handle error
}
