GkashFlutterSDK
This plugin allows you to integrate Gkash Payment Gateway into your Flutter App.
Usage
Sample usage to start a payment:
import 'package:gkash_payment/gkash_webview.dart';
import 'package:gkash_payment/model/payment_callback.dart';
import 'package:gkash_payment/model/payment_request.dart';
import 'package:gkash_payment/model/payment_response.dart';
requestPayment() {
//Generate your Payment Request
PaymentRequest request = PaymentRequest(
version: '1.5.0',
cid: "M102-U-xxx",
currency: 'MYR',
amount: amountInput,
cartid: DateTime.now().millisecondsSinceEpoch.toString(),
signatureKey: "yourSignatureKey",
isProd: false, //if production environment then set to true
callbackUrl: "https://YourCallbackUrl.com/callback", //set your callback URL (Optional)
paymentCallback: this);
//Navigate to GkashWebView
Navigator.of(navigatorKey.currentState!.context).push(
MaterialPageRoute(
builder: (_) {
return GkashWebView(request);
},
),
);
}
Getting the Payment Result
Upon finishing of the WebView Activity, implement GkashPaymentCallback to your widget
class MyHomePage extends StatefulWidget {
@override
_MyHomePageState createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage>
implements PaymentCallback {
@override
void getPaymentStatus(PaymentResponse response) {
// handle payment response
setState(() {
_status = response.status;
_cartId = response.cartid;
_amount = response.amount;
_currency = response.currency;
_description = response.description;
_paymentType = response.PaymentType;
_poId = response.POID;
_cid = response.cid;
});
}
IOS
Fos IOS, you need to add URL schemes to get your transaction status and pass your URL scheme to GkashPaymentSDK
Apps can declare any custom URL schemes they support. Use the URL Types section of the Info tab to specify the custom URL schemes that your app handles.
