Question 1

flutter_inapp_purchase vs revenuecat for Flutter apps

Accepted Answer

flutter_inapp_purchase is open-source and based on the OpenIAP standard, offering vendor neutrality and no recurring costs, while RevenueCat is a paid service with more features like analytics and lifecycle management. Choose based on whether you prefer an open standard or a managed solution with additional tools.

Question 2

how to handle refunds and disputes with flutter_inapp_purchase

Accepted Answer

The plugin relies on OpenIAP's standardized flows, so refund handling typically involves platform-specific APIs or server-side validation; check the documentation for guidance on purchase updates and error codes, but be prepared for manual integration with app store consoles.

Question 3

does flutter_inapp_purchase support family sharing on iOS

Accepted Answer

As per the OpenIAP specification, features like family sharing depend on platform implementations; the README doesn't explicitly mention it, so you may need to verify with openiap-apple packages or test directly, as support might be limited.

Question 4

how to test in-app purchases locally in development

Accepted Answer

Use platform sandbox environments; the plugin supports standard testing setups, but detailed steps aren't in the README—refer to the documentation site for specific guides on simulating purchases on iOS and Android.

Question 5

is flutter_inapp_purchase compatible with Flutter null safety

Accepted Answer

Yes, the plugin version ^8.0.0 in the README indicates support for modern Flutter with null safety, but always check pub.dev for the latest compatibility and migration notes if using older Flutter versions.

Question 6

what happens if OpenIAP changes its specification

Accepted Answer

Updates to the OpenIAP spec may require plugin upgrades, potentially introducing breaking changes; the README shows active maintenance via CI badges, but you'll need to monitor releases and adapt your code accordingly.
