This package supports in-app purchases (IAP) through an underlying store, which can be the App Store (on iOS) or Google Play (on Android).
Today I will be demonstrating how to list purchases, listen for updates to a new purchase, and subscribe to a product, (subscription).
You can download the package @ pub.dev/packages/in_app_purchase
Source Code: github.com/trey-a-hope/Demos/...
Sandbox Testing: developer.apple.com/apple-pay...

Thanks for this great demo! Question: Question you may have the answer: When you buy a product that you already subscribed, there is alert showing up saying "You're currently subscribed.." Once you Tap OK; the Purchase status changes from Pending to Purchased, but do you know how to catch the event ? I guess we should not handle it like an effective purchase.

@TreyHope Жыл бұрын

Thank you for watching. I believe that event should be caught in the listen to purchases stream, but I’m not entirely sure.

Thank you Trey for this video, this is very informative and has helped to clarify my doubts. I have one question: When a user has subscribed (paid for the monthly subscription), do we need to maintain this information in our backend servers? For example, I want 1 month free usage and then initiate the monthly subscription. For this to work, do I need to implement anything on the backend or can I just rely on the app to check it? Thank you in advance :)

@TreyHope Жыл бұрын

Hey there, thank you for watching the video; I’m glad you found it helpful. That’s a very good question. It looks like you can provide a trial period to your subscriptions in the App Store & Play Store, so you wouldn’t need to maintain any extra data. I hope I answered your question.

@@TreyHope Thank you for quick response. Understood, that makes sense. Do you still think that App developer should verify the payment status from the Apple/Google via server verification?

@TreyHope Жыл бұрын

Yes, it’s good practice to. I haven’t for some of the apps I’ve worked on, which isn’t something I’m proud of lol, but it is in best interest to verify the payments via server verification.

@@TreyHope yes in documentation of in-app-purchases flutter package, they have mentioned we need to have a backend to validate purchases on google and apple way, But in your example you didnt validate, so what i was trying to know can you implement IAP without a server backend?

@TreyHope 2 жыл бұрын

@@waseemsheikh9545 I understand now. So from what I read, backend validation is not necessary, (in app purchases will still work without it), but it provides some advantages. Some of those include advanced payment analytics, being able to verify the purchase’s authenticity, cross platform subscriptions, and being able to control content access from the server side. Hopefully this helps.
