Stripe 错误：客户尚未在 flutter 中输入他们的支付方式

问：

我使用 Firebase CLI 在我的 flutter 应用程序中集成了 flutter_stripe 2.0.1 插件。从 firebase 提供的 URL 获取 paymentIntent 的成功响应。但在 Stripe 管理平台中，付款状态为“未完成”。

下面是我的 node.js 代码索引 .js 文件

const functions = require('firebase-functions');
const stripe = require('stripe')(functions.config().stripe.testkey);

exports.stripePayment = functions.https.onRequest(async (req, res) => {  
    const paymentIntent = await stripe.paymentIntents.create({
        amount: 1,
        currency: 'usd'
    },
        function(err, paymentIntent) {
            if(err != null){
                console.log(err);
            } else {
                res.json({
                    paymentIntent: paymentIntent.client_secret,
                })
            }
        }
    )

});

下面是我的 flutter 代码

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  Stripe.publishableKey = stripePublishableKey;
  Stripe.merchantIdentifier = 'merchant.flutter.stripe.test'; //any string works
  await Stripe.instance.applySettings();
  runApp(MyApp());
}

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

  @override
  Widget build(BuildContext context) {
      return MaterialApp(
        home: DashboradPage(),
      );
  }
}

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

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

class _DashboradPageState extends State<DashboradPage> {
  Map<String, dynamic>? paymentIntentData;

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: const Text('Stripe Examples'),
      ),
      body: Center(
        child: ElevatedButton(
          onPressed: () {
            makePayment();
          },
          child: Text('Pay Amount'),
        ),
      ),
    );
  }

  Future<void> makePayment() async {
    final url = Uri.parse(
        'https://us-central1-stripeflutterdemo.cloudfunctions.net/stripePayment');

    final header = {'Content-Type': 'application/json'};
    try {
      final response = await http.get(url, headers: header);
      paymentIntentData = json.decode(response.body);
      await Stripe.instance.initPaymentSheet(
            paymentSheetParameters: SetupPaymentSheetParameters(
          paymentIntentClientSecret: paymentIntentData?['paymentIntent'] ?? '',
          applePay: true,
          googlePay: true,
          style: ThemeMode.light,
          merchantCountryCode: 'US',
          merchantDisplayName: 'Flutter Stripe Store Demo',
        ));
        setState(() {});
       displayPaymentSheet();
    } catch (e) {
      print(e);
      displaySnackbar(e.toString());
    }
  }

  Future<void> displayPaymentSheet() async {
    try {
      await Stripe.instance.presentPaymentSheet();
      // await Stripe.instance.presentPaymentSheet(
      //   parameters: PresentPaymentSheetParameters(
      //     clientSecret: paymentIntentData?['paymentIntent'] ?? '',
      //     confirmPayment: true,
      //   ),
      // );

      setState(() {
        paymentIntentData = null;
      });
      displaySnackbar('Payment succesfully completed');
    } catch (e) {
      print(e);
      displaySnackbar(e.toString());
    }
  }

  void displaySnackbar(String msg) {
    ScaffoldMessenger.of(context).showSnackBar(
      SnackBar(
        content: Text(msg),
      ),
    );
  }
}

以下是 makePayment（） 中提到的 URL 的邮递员响应

我使用了付款表，当我点击“付款”按钮时，它重定向到 webview（身份验证已完成），但在 Stripe 管理平台中，付款状态为“未完成”。
