hello, how to support voice messages

backend written in java, any plan add a go version for faster speed and easily deploy? (i'd like willing to have a try if there enough guidelines.

"InvalidProtocolBufferException: Protocol message end-group tag did not match expected tag."

Has anyone encountered this error in flutter?

when app goes background ,it will sleep by android ssytem.

But when comes back to foreground, it will reconnects, but server didn't recognise it offline..

BTW, my app won't exist, but just back to home, so it not restart everytime.

Finally after fix some bugs in your backend server java code, I got it run now.

But some problems really bad:

1). the messages can not sort by time (not distinguish coming msgs or my msgs, it should natrually sort by time, but now , its not;

2. Can not send Chinese.

3. Can not send picture.

Please check my powerful chatbot base on Python SDK:

Hi. I have made writen a chatbot based on this client possible!

And, it was really powerful and convenient to make a bot for anyone.

I am so happy to share the final version based on flutter-mqtt-chat-client, thanks for original ops wonderful job.

For future any body interested on this project:

• You can found python SDK on opensource git url: https://github.com/jinfagang/alfred
• If you want make a chatbot, you can using my another opensource which will be available soon
• You can built any command, function based on your bot and MQTT service! For example, using ESP8266 to control your light!

Hi WahidNasri,

I can't find out how to register a user.

After building the app, here is the terminal output (sorry it seems a bit long)

$ flutter run ...

`💪 Running with sound null safety 💪

Also I couldn't find the documentation, so I added the dependency into the same directory as this repository and apparently I can run the application, but in order to login, I must register, right?

its showing on hive, but i cant see it inside the application.

Just for anyone also interested in this project, I believe op gets a very impressive implementationon mqtt chatter. But after I tried the default Java backend, it was messy to be honest, So i re-written it into Golang, now

It looks great, everything works fine. So that mine and share a same client with ops, but with different backend.

Here is some screen shot of mine:

The enhancement based on this version, I did:

• Dark mode switch;
• Users can change their profiles directly in Client;
• Send picture support on Linux && Windows;
• Send picture now can save in local, both PC && phone supported;
• Fix some backend SQL query problems in ops version.
• now we support Chinese && Janpaness, input and sending

hi， how about add mainflux backbone support as well?

Hi, how to make new messages coming can have a red dots at session page?

Any ideas?
