How hard is it to migrate a larger production app from Xamarin.Forms to Flutter?
Hey guys,I know there are some more posts about the migration from Xamarin.Forms to Flutter and i also know there is a great section in the flutter docs that show how you can migrate your UI and code to Flutter. I've been building a production iOS/Android app for the past 3-4 years in Xamarin.Forms and i have to say i really love C# but the struggles i had with bugs and somehow, in my opinion, weird concepts for layouts (e.g. making your layout responsive for multiple devices which is a pain in the a$$ in Xamarin.Forms) really cost me a lot of time. Additionally our app clients ask for desktop support for the app and i feel like waiting for .NET MAUI is a bit too risky as i have no idea when it will be released.I'm ready to invest some time in the Migration but i want to make it as easy as possible. I'd like to copy all the app logic classes (network, data handling, etc) one to one as it works fine in C# and I'm happy to rebuild a lot of the UI anyways, as i think it has some potential to be better. Is there actually a way to transpile C# .NET code to Dart or do i need to do this manually line by line? I'm using so much Linq and for example i have a customized TCP socket which I have no idea if i can migrate it to Dart or not? Excuse me if these questions are quite basic, i have migrated projects before but never from one programming language to another.For the end user i want a seamingless transition to the new app. In the appstore it should basically be a new big update for the old app and that's about it. From what i read that should be possible anyways.Thanks in advance and I'm happy to hear your Migration stories!

Feedback needed on in-app purchase implementation
Hey everyone! I implemented in-app purchases in Flutter. I used the official plugin in_app_purchase. I would like to be sure that I did everything correctly. Any feedback is very much appreciated! Following is what I did:1) I load all products from store:

final isAvailable = InAppPurchase.instance.isAvailable(); if(isAvailable){ final response = await IAPInstance.queryProductDetails(skis.toSet()); products.value = response.productDetails; } 

2) Then I start listening to the purchaseUpdated stream

 void _listenToPurchaseUpdated( List<PurchaseDetails> purchaseDetailsList, ) async { if (purchaseDetailsList.isEmpty) { return; } final purchaseDetails = purchaseDetailsList.first; if (purchaseDetails.status == PurchaseStatus.pending) { // PENDING } else { if (purchaseDetails.status == PurchaseStatus.error) { // HANDLE ERROR } else if (purchaseDetails.status == PurchaseStatus.purchased || purchaseDetails.status == PurchaseStatus.restored) { final token = purchaseDetails.verificationData.serverVerificationData; final productId = purchaseDetails.productID; // Here I check if token is valid, and if it is, I update user data in DB final isValid = await checkIsTokenValid(productId, token); if (isValid) { // Show dialog, that purchase was completed successfully if (purchaseDetails.pendingCompletePurchase) { // QUESTION_1: when purchase status is restored, pendingCompletePurchase is always "false". I don't need it to call when purchase is autorenewed? await IAPInstance.completePurchase(purchaseDetails); } } else { // HANDLE ERROR } } } } final Stream purchaseUpdated = IAPInstance.purchaseStream; _subscription = purchaseUpdated.listen((purchaseDetailsList) { _listenToPurchaseUpdated(purchaseDetailsList); }, onDone: () { print('On done callback called'); _subscription.cancel(); // QUESTION_2: Why I cancel subscription here? Is it necessary? }, onError: (error) { // handle error here. print('Error callback called: $error'); }); 

3) When the user wants to buy a subscription, I do this:

final PurchaseParam purchaseParam = PurchaseParam(productDetails: details); await IAPInstance.buyNonConsumable(purchaseParam: purchaseParam); 

It will fire an event and the stream callback will be executed.4) The biggest question is about auto-renewal:4.1) When user is outside of app, and the subscription is renewed, how can I detect it and update in my DB? (Both for iOS and Android). My solution is to call IAPInstance.restorePurchase() when app is opened the first time. This will fire purchaseUpdated callback with "restored" purchase status, and then I do my validation with backend, which will check the token and then change user subscription expiration date in my DB. But when I check purchaseDetails.pendingCompletePurchase, it always returns false, when status is restored. Shouldn't I call completePurchase() when purchase is restored? Am I doing it correctly?4.2) When the user is in foreground, i.e. in the application, and subscription expires and renewed, purchaseUpdated callback is not called :(( What to do here? Check expiration time on app open and set timer for calling IAPInstance.restorePurchase()? I think this will also fire the purchaseUpdated callback with "restored" purchase status.P.S. In testing mode, monthly subscription duration is 5 minute, and when I don't open app long time, when I come back, there is no subscription. Is it OK? Is it only because of my test card?Thank you very much!
