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:

Import the package:

import 'package:upi_payment_flutter/upi_payment_flutter.dart';

Create an instance of the UpiPaymentHandler class:

final upiPaymentHandler = UpiPaymentHandler();

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
}
