Flutter支付集成插件woosignal_stripe的使用

Flutter支付集成插件woosignal_stripe的使用

woosignal_stripe 是一个用于在WooSignal应用中集成Stripe支付的官方包。以下是如何使用该插件的详细指南。

安装插件

首先，在你的 pubspec.yaml 文件中添加 woosignal_stripe 依赖项：

dependencies:
  woosignal_stripe: ^版本号

然后运行 flutter pub get 来安装依赖项。

配置插件

在你的应用初始化时，配置 woosignal_stripe 插件。你需要设置Apple Pay商户标识符（如果适用）以及其他相关参数。

import 'package:flutter/material.dart';
import 'package:woosignal_stripe/woosignal_stripe.dart';

void main() => runApp(MyApp());

class MyApp extends StatefulWidget {
  [@override](/user/override)
  _MyAppState createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  String _paymentMethodId;

  [@override](/user/override)
  void initState() {
    super.initState();
    FlutterStripePayment.setStripeSettings(
        applePayMerchantIdentifier: "{STRIPE_APPLE_PAY_MERCHANTID}", // 替换为你的Apple Pay商户标识符
        stripeAccount: "", // 如果使用Connect账户，则填写Connect账户ID
        liveMode: false); // 是否使用生产模式
  }

  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: const Text('Stripe App Example'),
        ),
        body: Center(
          child: Column(
            mainAxisAlignment: MainAxisAlignment.center,
            children: [
              _paymentMethodId != null
                  ? Text(
                      "Payment Method Returned is $_paymentMethodId",
                      textAlign: TextAlign.center,
                    )
                  : Container(),
              ElevatedButton(
                child: Text("Add Card"),
                onPressed: () async {
                  var paymentResponse = await FlutterStripePayment.addPaymentMethod();
                  setState(() {
                    _paymentMethodId = paymentResponse.paymentMethodId;
                  });
                },
              )
            ],
          ),
        ),
      ),
    );
  }
}
