Firebase函数未在Firebase中创建Stripe令牌字段（颤振）

Question

我完全遵循了本教程：https://www.youtube.com/watch?v=JeyxolsJ3aE

我能够获得我的代码以使用Firebase身份验证创建新的带区客户，并且能够提交令牌并在带区中看到它。但是，将令牌发送到条带化之后，没有任何其他反应。令牌的详细信息应该显示在数据库中（但什么都没有显示。）。请帮助...

颤振代码：

import 'package:flutter/material.dart';
import 'package:stripe_payment/stripe_payment.dart';
import 'package:flutter/cupertino.dart';

PaymentMethod paymentMethod;
final CreditCard testCard = CreditCard(
  number: '4242424242424242',
  expMonth: 12,
  expYear: 21,
);

class donationPage extends StatefulWidget {

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

class donationPageState extends State<donationPage> {


  @override
  initState() {
    super.initState();

    StripePayment.setOptions(
        StripeOptions(publishableKey: "mykey", merchantId: "Test", androidPayMode: 'test'));
  }

  @override
  Widget build(BuildContext context) {

   return  Scaffold(
        body: SafeArea(

          child: ListView(
              children: <Widget>[
                Container(
                    margin: EdgeInsets.only(top: 4.0, right:2, left: 2),
                    height: 60,
                    width: 120,
                    child: ButtonTheme(
                        child: RaisedButton(
                            color: Colors.teal,
                            child: Text('\$100'),
                            onPressed: () async {

   await StripePayment.createTokenWithCard(testCard);


})))]);


  }
}

然后，firebase函数的index.js文件如下所示（与说明相同）：

const functions = require("firebase-functions");
const { allowedNodeEnvironmentFlags } = require("process");
const admin = require("firebase-admin");
const stripe = require("stripe")(functions.config().stripe.secret, {
  apiVersion: "2020-03-02",
});

exports.createStripeCustomer = functions.auth.user().onCreate(async (user) => {
  const customer = await stripe.customers.create({ email: user.email });
  const intent = await stripe.setupIntents.create({
    customer: customer.id,
  });
  await admin.firestore().collection("stripe_customers").doc(user.uid).set({
    customer_id: customer.id,
    setup_secret: intent.client_secret,
  });
  return;
});

exports.addPaymentMethodDetails = functions.firestore
  .document("/stripe_customers/{userId}/payment_methods/{pushId}")
  .onCreate(async (snap, context) => {
    try {
      const paymentMethodId = snap.data().id;
      const paymentMethod = await stripe.paymentMethods.retrieve(
        paymentMethodId
      );
      await snap.ref.set(paymentMethod);
      // Create a new SetupIntent so the customer can add a new method next time.
      const intent = await stripe.setupIntents.create({
        customer: paymentMethod.customer,
      });
      await snap.ref.parent.parent.set(
        {
          setup_secret: intent.client_secret,
        },
        { merge: true }
      );
      return;
    } catch (error) {
      await snap.ref.set({ error: userFacingMessage(error) }, { merge: true });
      await reportError(error, { user: context.params.userId });
    }
  });

请帮助。谢谢，Ev
