Implementing PayPal Payment Method in Flutter using flutter paypal Package


The flutter_paypal package provides an easy way to integrate PayPal payment functionality into your Flutter app. This guide will show you how to use this package to implement PayPal payments in your Flutter app.


1.Add the flutter_paypal dependency:

Open your pubspec.yaml file and add the flutter_paypal dependency.

  flutter_paypal: ^latest_version

Run flutter pub get to install the package


2.Import the package:

Import the flutter_paypal package in your Dart file.

import 'package:flutter_paypal/flutter_paypal.dart';


3.Set up PayPal:

Initialize PayPal with your client ID and secret. You can obtain these credentials by creating a PayPal developer account and registering your app.

void initPayPal() {
    clientId: 'YOUR_CLIENT_ID',
    secret: 'YOUR_SECRET',
    environment: PayPalEnvironment.sandbox, // Or PayPalEnvironment.production for production environment


4.Make a payment:

Use the PayPal.requestPayment method to initiate a PayPal payment. Provide the amount, currency, and description for the payment.

void makePayment() async {
  PayPalPaymentDetails paymentDetails = PayPalPaymentDetails(
    amount: '10.00',
    currency: 'USD',
    description: 'Payment for your order',

  PayPalPaymentResponse paymentResponse = await PayPal.requestPayment(
    paymentDetails: paymentDetails,

  if (paymentResponse.status == PayPalStatus.success) {
    // Payment successful
  } else {
    // Payment failed


5.Handle payment response:

Check the status of the payment response to determine if the payment was successful or failed.


6.Handle errors:

Implement error handling to manage any issues that may occur during the payment process

Sample Code

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

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

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  // This widget is the root of your application.
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Paypal',
      theme: ThemeData(
      home: const MyHomePage(title: 'Flutter Paypal Example'),

class MyHomePage extends StatefulWidget {
  const MyHomePage({Key? key, required this.title}) : super(key: key);
  final String title;

  State<MyHomePage> createState() => _MyHomePageState();

class _MyHomePageState extends State<MyHomePage> {
  Widget build(BuildContext context) {
    return Scaffold(
        appBar: AppBar(
          title: Text(widget.title),
        body: Center(
