I am building a Flutter app where I need to track user logins and logouts and store this information in a Firestore collection. Specifically, I want to store the user’s name, ID, and compound location whenever they log in or log out.

I’m developing a Flutter application where I have a ContactsPage that fetches user profiles from Firestore and allows navigation to a ChatPage for each contact. I want to display the userName and userImageLink in the AppBar of ChatPage just like WhatsApp does.

I’m developing a Flutter application where users can chat with each other. I’ve successfully implemented user authentication and profile creation. Now, I’m trying to display the user’s profile data, including their image and name, in the chat screen’s app bar. Additionally, I want to show the last seen status of the user.

I want to put the code of individual page inside chat screen page and add in route arguments imagelink and name documents of userProfile collection from firebase to show it in appbar in chatscrreen enter image description here

I have this model for a map of maps in Firebase.

I’m watching a StreamProvider and one of the fields of the returned result is a LinkedMap<String,dynamic>

I’m encountering a problem in my Flutter (Dart) code for a chat group I’m building. The issue arises in the chat screen where, upon testing, all messages appear on the right side, even when sent by different users.
How can I ensure proper alignment of messages in my Flutter chat app, where messages sent by different users appear on the correct side of the screen, and include relevant user information such as sender name and timestamp?
I’ve included the relevant code snippets below. Any assistance would be greatly appreciated. Thank you!
