Introduction

This extension wraps Google's Play Billing Library (version 9.1.0), so it is only supported on Android. Before using any other function you must initialize the extension with play_billing_init and connect to the Play Store with play_billing_start_connection.

We recommend reviewing Google's own Billing Overview documentation before using this extension, as it introduces the concepts (products, purchases, acknowledgement, consumption) that the functions here map onto closely.

Important

Purchase results are NOT returned directly by play_billing_launch_billing_flow. Every purchase - however it was started - is delivered through the single callback registered in play_billing_init, which fires for the lifetime of the client.
