Usage

1. Initialize Alipay

import 'package:flutter_alipay_plugin/flutter_alipay_plugin.dart';

final alipayPlugin = FlutterAlipayPlugin();

// Initialize Alipay
final success = await alipayPlugin.initAlipay(
  appId: 'your_app_id',

2. Initiate payment

// Order info is usually generated by server
final orderInfo = 'your_order_info_from_server';

final result = await alipayPlugin.pay(

  isShowPayLoading: true, // Whether to show payment loading UI
);

// Handle payment result
if (result['success'] == true) {
  print('Payment successful');
} else {
  print('Payment failed: ${result['memo']}');

Payment Result Status Codes

These status codes are officially defined by Alipay SDK, not custom defined. They are returned by the PayTask.payV2() method from Alipay Android SDK.

Status Code	Description	Source
9000	Order payment successful	Alipay SDK Official
8000	Processing, payment result unknown	Alipay SDK Official
4000	Order payment failed	Alipay SDK Official
5000	Duplicate request	Alipay SDK Official
6001	User cancelled	Alipay SDK Official
6002	Network connection error	Alipay SDK Official
6004	Payment result unknown	Alipay SDK Official

Note: These status codes are standard Alipay SDK responses and do not need to be negotiated with your backend service.
