I have a Flutter app using last version of RevenueCat libs (purchases_flutter and purchases_ui_flutter, both at 6.29.2).
The Purchases instance is configured during app initialization:
Future<void> setupRevenueCatSDK() async {
await Purchases.setLogLevel(LogLevel.debug);
late PurchasesConfiguration configuration;
if (Platform.isAndroid) {
configuration = PurchasesConfiguration("XXX");
} else if (Platform.isIOS) {
configuration = PurchasesConfiguration("XXX");
}
await Purchases.configure(configuration);
logger.d("RevenueCat / Purchases configured ${configuration.appUserID}");
}
void main() async {
WidgetsFlutterBinding.ensureInitialized();
// ...
await setupRevenueCatSDK();
// ... runApp
}
Then I call the UI lib to open the Paywall, after the user taps a button.
response = await RevenueCatUI.presentPaywall()
This flow works well for all devices I could test (both iOS and Android) and I had many multiple transactions from other users. Still, I'm seeing dozens of multiple crashes on Crashlytics:
Fatal Exception: z5.I: There is no singleton instance. Make sure you configure Purchases before trying to get the default instance. More info here: https://errors.rev.cat/configuring-sdk

The interesting part is that those errors are raised right after opening the app, without user interaction (Crashlytics displays as "< 1 second crash" -- see screenshots).
What I'm I missing?
