Hey FlutterFlow community! :waving_hand:
If you’re planning to build a live chat feature (like WhatsApp or Messenger) in FlutterFlow, here’s a simple guide on how to do it efficiently and in real-time! :rocket:

:wrench: Recommended Setup:

Use Firebase Firestore (because of its real-time syncing) + FlutterFlow’s built-in chat features or custom widgets.

:brick: Steps to Build Live Chat:

:one: Create Firestore Collections

  • Chats → Stores each chat session
  • Messages → Stores messages for each chat (linked to chat_id)

:two: Design Your Pages

  • Chat List Page: Shows all ongoing chats
  • Chat Page: Displays messages & input field

:three: Add Realtime Firestore Query
Use a Firestore Query widget with orderBy Timestamp ASC to auto-update messages as they come in.

:four: Add Message Input
Use a TextField + Send Button → onPress action: Create Document in “Messages”

:light_bulb: Best Practices:

:white_check_mark: Use currentUserReference to track sender
:white_check_mark: Store messages with sender, text, timestamp, chat_id
:white_check_mark: Use streamed data to keep chats live
:white_check_mark: Optional: add push notifications with Firebase for new messages

:test_tube: Example: Firestore Message Document

CopyEdit

{
  "chat_id": "abc123",
  "sender": "user_ref",
  "text": "Hello!",
  "timestamp": "serverTimestamp"
}

:high_voltage: Performance Tips:

  • Limit query to last 50–100 messages for faster loading
  • Use ListView with reverse scrolling
  • Add auto-scroll on new message
