}

class MyApp extends StatefulWidget {
  const MyApp({super.key});

              Expanded(
                child: KlarnaPaymentView(
                  controller: controller,
                  request: KlarnaPaymentRequest(
                    clientToken: token,
                    returnUrl: 'https://com.example.flutter_klarna_payment',
                  ),

              ElevatedButton(
                  onPressed: () {
                    controller.pay();
                  },
