from what I can see apparently the text widget you use in your "messagebubbles" isnt actually getting any data ie. the string variable is null from what I can see, you did final messageText = message.data['text']; final messageSender = message.data['sender']; using the .get method on the "message" object should fix it : final messageText = message.get('text'); final messageSender = message.get('sender');

alternatively final messageText = message['text']; final messageSender = message['sender'];

yeah, thanks to you all for your comments, actually I already fixed the problem. it was actually coming from my firebase set up. I was passing a null argument into my fire base
