How do I use RevenueDot with Flutter?

Call await Purchases.setProxyURL('https://revenuedot.example.com') before Purchases.configure. Verification is already disabled by default in purchases_flutter, so there is nothing else to change on iOS and Android. Flutter web does not work in proxy mode with the stock package: its web plugin ignores setProxyURL, so web calls still go to RevenueCat. The RevenueDot fork fixes this.

Use the RevenueCat SDK you already ship (proxy mode)#

import 'dart:io' show Platform;
import 'package:purchases_flutter/purchases_flutter.dart';

Future<void> initPurchases() async {
  // Point the SDK at your RevenueDot server; nothing else in the app changes.
  await Purchases.setProxyURL('https://revenuedot.example.com');
  await Purchases.configure(
    PurchasesConfiguration(Platform.isIOS ? 'appl_...' : 'goog_...'),
    // entitlementVerificationMode stays at its default, EntitlementVerificationMode.disabled.
  );
}

• Await setProxyURL before configure.
• Use each app's public key from RevenueDot, or your old RevenueCat keys if the importer kept them. See Which key goes where.

After you migrate from RevenueCat, sync once on the first launch of the update, so current subscribers keep access:

// Once, after this update: send purchases made while the app talked to RevenueCat.
await Purchases.syncPurchases();

Use the RevenueDot fork#

The fork is github.com/revenuedot/purchases-flutter. The package names stay purchases_flutter and purchases_ui_flutter, so every import 'package:purchases_flutter/purchases_flutter.dart' keeps working. It also makes setProxyURL work on Flutter web.

It is not published yet (2026-09-30). It will ship as a git dependency with release tags <version>-revenuedot, because pub.dev names belong to RevenueCat:

# pubspec.yaml (planned)
dependencies:
  purchases_flutter:
    git:
      url: https://github.com/revenuedot/purchases-flutter.git
      ref: <version>-revenuedot

The patch branch revenuedot/main-patches is at version 10.13.2. Pointing ref at that branch resolves the Dart package, but iOS and Android builds fail today: the native side needs the RevenueDotPurchasesHybridCommon pod and the app.revenuedot.purchases:purchases-hybrid-common Maven artifact, which are not published. See Hybrid common.

Trusted Entitlements are off by default#

• Stock package: entitlementVerificationMode defaults to EntitlementVerificationMode.disabled, which is right for RevenueDot. informational logs every response as a failed signature check, and enforced would fail every request.
• Fork: it trusts RevenueDot Cloud's key. A self-hosted server signs with its own key, so keep disabled, or build the forks with your own public key.

See Trusted Entitlements.

Check an entitlement and make a purchase#

import 'package:flutter/services.dart' show PlatformException;

final customerInfo = await Purchases.getCustomerInfo();
final isPro = customerInfo.entitlements.active.containsKey('pro');

final offerings = await Purchases.getOfferings();
final package = offerings.current?.availablePackages.first;
if (package != null) {
  try {
    final result = await Purchases.purchase(PurchaseParams.package(package));
    final nowPro = result.customerInfo.entitlements.active.containsKey('pro');
  } on PlatformException catch (e) {
    if (PurchasesErrorHelper.getErrorCode(e) != PurchasesErrorCode.purchaseCancelledError) rethrow;
  }
}

Purchases.purchasePackage still works but is deprecated in 10.x.

Test Store#

Create a test_store app in RevenueDot and use its test_... key. The Test Store dialog replaces the store sheet; tap Test valid purchase.

• Native builds accept test_ keys only in debug builds. Ship with the appl_ and goog_ keys.
• iOS: servers older than the 2026-09-30 fix could not serve Test Store products to the native iOS SDK. See iOS.
• Flutter web needs the fork, because the stock web plugin ignores the proxy URL.
• Test Store prices come from each product's Test Store price. Set it in the dashboard (Product catalog, Edit product) or with test_store_price on POST /v2/projects/{project_id}/products; a product without one shows 0.

Migrate from RevenueCat#

 import 'package:purchases_flutter/purchases_flutter.dart';

 Future<void> initPurchases() async {
+  // Point the SDK at your RevenueDot server; nothing else in the app changes. Await it before configure.
+  await Purchases.setProxyURL('https://revenuedot.example.com');
   await Purchases.configure(PurchasesConfiguration(Platform.isIOS ? 'appl_...' : 'goog_...'));
+  // Once, after this update: send purchases made while the app talked to RevenueCat.
+  await Purchases.syncPurchases();
 }

The full order of steps is in Migrate from RevenueCat.
