Hi, how do you manage to write the database with no user auth @7:18 ? I understand you've changed the database rules so no auth is required, and so it might not be related, but when I try to do it I get the error: updateChildren at / failed: DatabaseError: Invalid token in path. do you have an idea why? is there anything else you've modified in your firebase settings? I've taken a look at your src and I seem to have done everything the exact same way. thanks for the nice tutorials & help!

Also, what font are you using in the studio? It doesn't seem to be the default one.

Pls sir I've downloaded ur video, I love it. I'm suggesting that u put an indicator or a snackmessage that will tell other users in the room that new user has joined the room or left the room

+Filip Vujovic I am curious, how can use type so fast? Even i am using auto complete, i don't think that i can do as you did there. Are you fast forwarding your video? If not, i must learn to do that to increase my productivity. Please give me a hint.

Hi Filip, Thanks for sharing your knowledge with all of us, could you tell me how it could be done so that at the time of writing the message the user's message was left on one side and the other user was on the other side, as handled in WhatsApp, Attentive to your answer.Thanks

Hello Filip Its really great to see you helping us out!
I need to ask you that while + " : " + message + " \n"); in this line of code you save the data into that tree of firebase and also the same time you print it too but what if i just want it to be save in that but not print so how do i do that?
