Please note the onBackgroundMessage part. Not implementing it as well as the others gave me the Failed to find callback error

Replace GeneratedPluginRegistrant.registerWith(registry); with

FirebaseMessagingPlugin.registerWith(registry.registrarFor("io.flutter.plugins.firebasemessaging.FirebaseMessagingPlugin"));
