• Easy-to-integrate package designed for simplicity, ensuring a smooth setup process.

Getting started

After adding the package to your pubspec.yaml, make sure to import it

import 'package:paypal_webview/paypal_webview.dart';

You can checkout a simple illustration in the /example folder.

Usage

To seamlessly integrate PayPal payments into your application using this package, follow these straightforward steps in your code:

Initiate the integration process by creating an MDPurchaseItems model, which serves as a fundamental component for generating orders against the items you intend to sell.

class MDPurchaseItems {
  String? name;
  String? description;
  String? quantity;
  UnitAmount? unitAmount;

  MDPurchaseItems(
      {this.name, this.description, this.quantity, this.unitAmount});

  Map<String, dynamic> toJson() {
    final Map<String, dynamic> data = new Map<String, dynamic>();
    data['name'] = this.name;
    data['description'] = this.description;
    data['quantity'] = this.quantity;
    if (this.unitAmount != null) {
      data['unit_amount'] = this.unitAmount!.toJson();
    }
    return data;
  }
}

class UnitAmount {
  String? currencyCode;
  String? value;

  UnitAmount({this.currencyCode, this.value});

  Map<String, dynamic> toJson() {
    final Map<String, dynamic> data = new Map<String, dynamic>();
    data['currency_code'] = this.currencyCode;
    data['value'] = this.value;
    return data;
  }
}

Next, establish the MDPayPal model to seamlessly obtain the payment ID upon successful transactions—a crucial step in streamlining the payment process.

class MDPayPal{
  String? paymentId;
  String? token;
  String? payerID;

  MDPayPal( String paymentId, String token, String payerID){
    this.paymentId = paymentId;
    this.token = token;
    this.payerID = payerID;
  }

}

Here's a concise and professional full implementation for seamlessly integrating PayPal payments into your application:

class HomePage extends StatefulWidget {
  const HomePage({Key? key}) : super(key: key);

  @override
  _HomePageState createState() => _HomePageState();
}

class _HomePageState extends State<HomePage> {

  /// Create list using MDPurchaseItems Model for generating order against your products
  List<MDPurchaseItems> purchaseItems = [
    MDPurchaseItems(
        name: 'T-Shirt',
        description: 'Green XL',
        quantity: '1',
        unitAmount: UnitAmount(currencyCode: 'CAD', value: '10')),
  ];

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        backgroundColor: Color(0xff252C39),
        title: Text('PayPal Demo Screen'),
        centerTitle: true,
      ),
      body: Center(
        child: ElevatedButton(
          onPressed: () {
            Navigator.of(context)
                .push(
              MaterialPageRoute(
                builder: (context) => PayPalWebView(
                  /// you will find the client Id after login to paypal developer account .
                  clientId: 'ATBV7KdKvDd9sGHYL4*******************************',


                  /// you will find the secret key after login to paypal developer account .
                  secretKey: 'EEitYKcFpiUCXplgxm*******************************',
                  currencyCode: 'CAD',
                  totalAmount: '10',
                  purchaseItems: purchaseItems,

                  /// sandboxMode true for testing purposes
                  sandbox: true,
                ),
              ),
            )
                .then((value) async {
              if (value != null) {

                /// After Successful Transaction you will receive MDPayPal Model type Data from which paymentId is use to verify payments
                MDPayPal paypal = value;
                print("The paypal Token is:" + paypal.token.toString());
                print("the paypal payer id is:" + paypal.payerID.toString());
                print("The paypal id is: " + paypal.paymentId.toString());
              }
            });
          },
          style: ElevatedButton.styleFrom(
            primary: Color(0xff252C39), // Background color
          ),
          child: Text('PayPal'),
        ),
      ),
    );
  }
}

With these simple code snippets, you can seamlessly integrate PayPal payments into your app, allowing for a smooth and secure transaction experience.
