Stripe Flutter cannot show fee in IOS simulator

I am working Flutter Stripe with this library : https://pub.dev/packages/flutter_stripe.

That is the operate from my bloc to create efficiently fee intent and show the fee sheet.

paymentSink.add(Standing.Loading);
logData(key, 'Stripe Pay');
//create fee intent
var response = await paymentRepository.createPaymentIntent(200, 'USD');
paymentSink.add(Standing.Profitable);
var paymentIntentData = json.decode(response.physique);
await stripe.initPaymentSheet(
    paymentSheetParameters: SetupPaymentSheetParameters(
  applePay: true,
  googlePay: true,
  model: ThemeMode.darkish,
  testEnv: true,
  merchantDisplayName: 'Flutter Stripe Retailer Demo',
  customerId: paymentIntentData!['customer'],
  paymentIntentClientSecret: paymentIntentData['client_secret'],
  customerEphemeralKeySecret: paymentIntentData['ephemeralKey'],
));
//show fee sheet
await displayPaymentSheet();
if(isSuccessPaid){
  logData(key, 'isSuccessPaid: $isSuccessPaid');
  //deal with outcome after fee efficiently
}

and that is the show fee sheet operate

attempt {
  await stripe.presentPaymentSheet().then((worth) {
    isSuccessPaid = true;
  }).onError((error, stackTrace){
    GetIt.I<AppSnackBar>().present(error.toString());
    logData(key,error.toString());
  });
} catch (e) {
  GetIt.I<AppSnackBar>().present(e.toString());
  logData(key, '$e');
}

The issue is Android simulator works completely like this

however the IOS simulator cannot show it and the terminal exhibits the errors like this

I do not know that is the platform error or simply the simulator drawback.Anybody acquired drawback like this?Please assist.Thanks!
