_tabController = TabController(length: 2, vsync: this);
super.initState();
billing();
// RustoreBillingClient.offNativeErrorHandling();
}
// Platform messages are asynchronous, so we initialize in an async method.
Future<void> billing() async {
RustoreBillingClient.initialize(consoleApplicationId, "example", true).then((value) {
print("initialize success: $value");
RustoreBillingClient.available().then((value) {

});

});
});
}

当然,以下是一个关于如何在Flutter应用中使用flutter_rustore_billing
插件实现应用内购买的示例代码。这个插件通常用于处理Google Play Store和App Store中的应用内购买。请注意,实际应用中你需要处理更多的错误处理和状态管理,这里只是提供一个基础示例。
首先,确保你已经在pubspec.yaml
文件中添加了flutter_rustore_billing
依赖:
dependencies:
flutter:
sdk: flutter
flutter_rustore_billing: ^x.y.z # 请替换为最新的版本号
然后运行flutter pub get
来安装依赖。
初始化购买插件
在你的Flutter应用的入口文件(通常是main.dart
)中,初始化flutter_rustore_billing
插件:
import 'package:flutter/material.dart';
import 'package:flutter_rustore_billing/flutter_rustore_billing.dart';
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
home: InAppPurchaseScreen(),
);
}
}
class InAppPurchaseScreen extends StatefulWidget {
@override
_InAppPurchaseScreenState createState() => _InAppPurchaseScreenState();
}
class _InAppPurchaseScreenState extends State<InAppPurchaseScreen> {
late FlutterRustoreBilling _billing;
@override
void initState() {
super.initState();
_billing = FlutterRustoreBilling.instance;
_initBilling();
}
Future<void> _initBilling() async {
try {
await _billing.initBilling();
print("Billing initialized");
// 获取产品详情
await _fetchProducts();
} catch (e) {
print("Failed to initialize billing: $e");
}
}
Future<void> _fetchProducts() async {
try {
List<ProductDetails> products = await _billing.getProductDetails(["product_id_1", "product_id_2"]);
// 在这里处理获取到的产品详情
print("Products: $products");
} catch (e) {
print("Failed to fetch products: $e");
}
}
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text('In-App Purchases'),
),
body: Center(
child: ElevatedButton(
onPressed: () {
// 这里添加购买逻辑
_purchaseProduct("product_id_1");
},
child: Text('Purchase Product'),
),
),
);
}
Future<void> _purchaseProduct(String productId) async {
try {
PurchaseParam purchaseParam = PurchaseParam(
productDetails: await _billing.getProductDetails([productId]).then((value) => value.first),
applicationUserName: "user_id_or_null", // 可以为null
);
PurchaseResult result = await _billing.buyConsumable(purchaseParam);
if (result.responseCode == BillingResponse.OK) {
print("Purchase successful: ${result.purchaseDetails}");
// 处理购买成功的情况
} else {
print("Purchase failed: ${result.debugMessage}");
}
} catch (e) {
print("Purchase error: $e");
}
}
}
注意事项
-
产品ID:在调用
getProductDetails
和buyConsumable
时,你需要使用实际的产品ID,这些ID需要在Google Play Console或App Store Connect中配置。 -
权限和配置:确保你的应用已经在Google Play Console或App Store Connect中配置了应用内购买,并且你的应用具有相应的权限。
-
处理购买结果:在实际应用中,你需要处理购买成功、失败、恢复购买等多种情况,并根据业务需求更新UI或服务器状态。
-
测试环境:在测试应用内购买时,请确保使用测试账号,并配置测试产品。
-
安全性:确保你的购买逻辑是安全的,避免被恶意用户绕过。
这个示例只是一个简单的入门示例,实际应用中你可能需要处理更多的细节和边缘情况。希望这个示例能帮到你!
