I'm building app for iOS with flutter and I encountered some problem implementing the IAP function. What I Encountered I made a purchase in simulator. The product list was load successfully, the storekit poped up, and I finished purchase successfully as well. But I cannot see transaction detail in the Storekit Manager in xcode, neither can I see notification send from Apple. I'm sure I configured the server URL in App Store Connect, and both chose V2. I'm sure I enabled Storekit in Edit Scheme, and sync with App Store Connect My server can receive Test Server Notification. What I Expected I want to receive the notification from Apple when make purchase from both develpment(simulator) and production(physical device). Otherwise I cannot verify the user's purchase.

I have a CRUD app built with flutter. Now I want to use Swift to create a widget to show the data at home screen. I use json to store the data. In the following code if I replace jsonURL with mock json string, everything works well. So I think the problem comes from accessing the local file. let sharedContainerURL = FileManager.default.containerURL(forSecurityApplicationGroupIdentifier: "group.com.app.identifier") let jsonURL = sharedContainerURL?.appendingPathComponent("things.json") And this is how I create the json file with Dart. Future<String> get _localPath async { final directory = await getApplicationDocumentsDirectory(); return directory.path; } Future<File> get _localFile async { final path = await _localPath; return File('$path/$storageName.json'); } In a nutshell the problem is that the widget cannot access the json file I created in the app storage. Everything works well except the widget.
