Current Behavior

When I upgraded capacitor with plugins from version 3 to 4 I cannot run android build. PushNotificationsPlugin throws me an error.

Build output:

/Users/myapp/Desktop/myapp_app_ionic/node_modules/@capacitor/push-notifications/android/src/main/java/com/capacitorjs/plugins/pushnotifications/PushNotificationsPlugin.java:79: error: cannot find symbol
            .getToken()
            ^
  symbol:   method getToken()
  location: class FirebaseMessaging

    @PluginMethod
    public void register(PluginCall call) {
        FirebaseMessaging.getInstance().setAutoInitEnabled(true);
        FirebaseMessaging
            .getInstance()
            .getToken()  // <- Cannot resolve method 'getToken' in 'FirebaseMessaging'
            .addOnCompleteListener(
                task -> {
                    if (!task.isSuccessful()) {
                        sendError(task.getException().getLocalizedMessage());
                        return;
                    }
                    sendToken(task.getResult());
                }
            );
        call.resolve();
    }

When I downgraded plugin to previous version ("@capacitor/push-notifications": "^1.0.7") it is working fine.

Expected Behavior

App should run without any issues

It looks like this issue didn't get the information it needed, so I'll close it for now. If I made a mistake, sorry! I am just a bot.

Since there was no response is hard to tell, but this is most likely caused by using an old firebaseMessagingVersion variable version in variables.gradle file. The capacitor 4 upgrade guide recommends to update it to 23.0.5. Or delete the firebaseMessagingVersion variable so the plugin always use the default one.
