Very good demo!

When I send a chat message, I got the below error.

java.lang.RuntimeException: An error occurred while executing doInBackground() at android.os.AsyncTask$4.done(AsyncTask.java:399) at java.util.concurrent.FutureTask.finishCompletion(FutureTask.java:383) at java.util.concurrent.FutureTask.setException(FutureTask.java:252) at java.util.concurrent.FutureTask.run(FutureTask.java:271) at android.os.AsyncTask$SerialExecutor$1.run(AsyncTask.java:289) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1167) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:641) at java.lang.Thread.run(Thread.java:919)

I just test it and everything fine when sending some messages on both iOS and Android. Seem this is a cloud_firestore bug described here FirebaseExtended/flutterfire#1969 when the internet is slow.

Something might be wrong inside the downloaded sources. I have changed it into my app packages environment, at first everything works fine, but after I executed as your extended push notification guide and then from that time it seemed to be go wrong. Your codes are very exciting to me, but I think It seems to be very hard work to resolve sending message problem.

I haven't clear detail your cases, but if you clone the source code and open it by Android Studio, get packages and then run as normal with nothing wrong happen (I also tested with new clone).
