How to implement subscription monthly in flutter? (New methods)

Question

I'm trying to implement a monthly subscription to my flutter app using in app purchase package.

After hours of searching I didn't find a actual example of a code that a user can press a button and pop up the subscription stuff. The ones that I found are outdated.

I read the documentation but I don't understand how to implement a simple way so the user can click a button and the payment subscription interface pops up and the user pays.

I know that I need to register the product in the Google and apple app stores. And more other things beside the code. I'm using the in_app_purchase: ^1.0.0

Thank you

Solution

This is not for in_app_purchases, but is regarding purchases in general.

I personally am using RevenueCat to manage my subscriptions. Its really fast and easy to implement, and the documentation is quite clear. Its available for both Android and iOS, they have a great platform that you can use to manage all subscriptions and users (even give them free access for a certain/unlimited amount of time.

I use it to manage almost 7k subscribers (both Android and iOS) and over 20k users. I haven't had a problem with them.

They are a SaaS company, but if you are making less than 10k in monthly revenue, then its free. Even after, its minimal and definitely worth it.

Here is the package and here is their documentation
