A common platform interface for the firebase_messaging plugin.

This interface allows platform-specific implementations of the firebase_messaging plugin, as well as the plugin itself, to ensure they are supporting the same interface.


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

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.
