Flutter 适用于谷歌支付的应用程序内购买工具
我正试图用flatter-Dart从Android Java更新我在google play store上的现有应用程序。在我现有的应用程序中,我有一个使用谷歌支付的应用程序内购买,它可以完美地工作(使用android java编码),但我正在寻找如何使用Flitter dart实现谷歌支付应用程序内购买。在应用程序内使用g支付应该没有问题。没有必要为此编写特定的代码。你只需要确保你正在谷歌计费平台上设置你的商户。查看本教程我发现google Pay不是一个支付网关,而是一个通往网关的阶梯,因此您必须将支付网关系统与google集成,并从我推荐的列表中选择。我将在下面解释 我遇到两个。实现这一目标的选择Flutter 适用于谷歌支付的应用程序内购买工具,flutter,dart,in-app-purchase,google-pay,Flutter,Dart,In App Purchase,Google Pay,我正试图用flatter-Dart从Android Java更新我在google play store上的现有应用程序。在我现有的应用程序中,我有一个使用谷歌支付的应用程序内购买,它可以完美地工作(使用android java编码),但我正在寻找如何使用Flitter dart实现谷歌支付应用程序内购买。在应用程序内使用g支付应该没有问题。没有必要为此编写特定的代码。你只需要确保你正在谷歌计费平台上设置你的商户。查看本教程我发现google Pay不是一个支付网关,而是一个通往网关的阶梯,因此您
GooglePay.initializeGooglePay("pk_test_H5CJvRiPfCrRS44bZJLu46fM00UjQ0vtRN");
这个插件的代码结构如下

import 'dart:async';
import 'package:flutter/services.dart';
import 'package:google_pay/google_pay.dart';
void main() => runApp(MyApp());
class MyApp extends StatefulWidget {

_MyAppState createState() => _MyAppState();
}
class _MyAppState extends State<MyApp> {
String _platformVersion = 'Unknown';
String _googlePayToken = 'Unknown';
@override
void initState() {
super.initState();
initPlatformState();
}
// Platform messages are asynchronous, so we initialize in an async method.
Future<void> initPlatformState() async {
String platformVersion;
// Platform messages may fail, so we use a try/catch PlatformException.
try {
platformVersion = await GooglePay.platformVersion;
} on PlatformException {
platformVersion = 'Failed to get platform version.';
}
await GooglePay.initializeGooglePay("pk_test_H5CJvRiPfCrRS44bZJLu46fM00UjQ0vtRN");
// If the widget was removed from the tree while the asynchronous platform
// message was in flight, we want to discard the reply rather than calling
// setState to update our non-existent appearance.
if (!mounted) return;
setState(() {
_platformVersion = platformVersion;
});
}
@override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
appBar: AppBar(
title: const Text('Plugin example app'),
),
body: Center(
child: Column(
children: <Widget>[

你检查过这个链接了吗?是的,我检查过,但没有工作。我尝试了这项工作,并启动了谷歌支付,但G支付显示了无法识别的应用程序。我想我必须改变等待谷歌支付。初始化谷歌支付(“pk_test_H5CJvRiPfCrRS44bZJLu46fM00UjQ0vtRN”);要挖掘但不知道如何获取wait \“pk_test_H5CJvRiPfCrRS44bZJLu46fM00UjQ0vtRN”本机移动应用,在苹果应用商店和/或谷歌游戏商店上收集数字商品付款通常需要使用应用内购买API,这意味着Stripe和Paypal等服务是不可能的(除了实际装运货物的付款)。尝试此官方Flitter插件,我需要在美国注册一个stripe帐户,对吗?如果您没有谷歌支持的支付提供商或网关,您可以访问此url申请使用商户帐户(直接)
