Square has announced the availability of two Square SDKs for Flutter, allowing developers to create cross-platform apps that can easily take payments.

A payments plug-in, built with the Google Play team, enables payment for physical goods on both iOS and Android. The in-app purchase plug-in, still in beta, has been updated.

Use the Flutter DynamicLibrary.open function to add them to your application, and then treat them much as you would a Flutter plug-in.
