A common platform interface for the google_api_availability plugin.

This interface allows platform-specific implementations of the google_api_availability plugin, as well as the plugin itself, to ensure they are supporting the same interface. Have a look at the Federated plugins section of the official Developing packages & plugins documentation for more information regarding the federated architecture concept.


To implement a new platform-specific implementation of google_api_availability, extend GoogleApiAvailabilityPlatform with an implementation that performs the platform-specific behavior, and when you register your plugin, set the default GoogleApiAvailabilityPlatform by calling GoogleApiAvailabilityPlatform.instance = MyGoogleApiAvailabilityPlatform().

Note on breaking changes

Strongly prefer non-breaking changes (such as adding a method to the interface) over breaking changes for this package.

See for a discussion on why a less-clean interface is preferable to a breaking change.
